The President. Dr. Isaac Hays, in the Chair.
Twenty-two members present.

Dr. Leidy called the attention of the members to the greater part of a human
skull, and a shell medallion, presented this evening by Col. A. W. Putnam, of
Nashville, Tenn. The specimens were obtained frcm one of the so-called pigmy
graves of an ancient aboriginal cemetery near the mouth of Stone River,
Davidson Co., Tenn.

The part of the skull consists of nearly the entire cranial portion, and does
Dot differ in general form, proportions and size, from that of the usual North
American Indian skulls. The occipital region is high, somewhat compressed,
and laterally deformed. The medallion is a circular piece of shell, about two
inches in diameter, and is much eroded. It appears to have been covered with
some pigment. One side is plain ; the other is marked with cross bars con-
tained within a linear circle. The upper edge is perforated with two holes.

Dr. L. read an extract fiom an article by Col. Putnam, in relation to the
specimens and the so-called pigmy race of Tennessee, published in the Nash-
ville Dispatch, Dec. 12, 1865. The substance of the extract is as follows :

The ancient cemeteries in middle Tennessee are peculiar from the construc-
tion and small size of the graves, which have given rise to the idea that they
belonged to a people of small stature. The graves are near the surface, and
so far as examined by Col. Putnam, or observed by the owners of lands on
which they are situated, and where the plow has uncovered them, are of quite
uniform structure. A few flat stones at the bottom, generally a single one at
the bead and foot, and a variable number at the sides. The grave thus pre-
pared, after receiving the human remains, was filled wi'h earth to the depth of
one or two feet, and was then covered with one or more flat stones, though
not in all instances. Col. Putnam supposes that recent dead bodies were not
deposited in their graves, but were exposed, according to the custom of some
of the later Indian tribes, on high scaffolds, or suspended to trees, in the open
air, until the soft parts had decayed, after which the bones were collected and
deposited in the stone graves. This would explain the reason of the small
size of the latter in comparison with the length of the entire skeletons con-
tained therein, and appears to receive confirmation from the fact that these
graves, notwiihstanding their very superficial position, never appear to have
been disturbed by wild animals, which they likely would have been had the
bodies been buried in the fresh condition.

fragilis and Harlani, taken from that bed by Prof. C.r seemed conclusive on
this point. The species is an Aturia, and the first found in the cretaceous for-
mation of New Jersey, though W. M. Gabb had discovered one perhaps the
same in the cretaceous of California. It, has some resemblance to the zic-zac,
but presents fewer and more diftant septa, longer chambers, and the parietal
processes of the septa more divaricate and less dorsally situate. It differs
from the A. Alabamensis (Morton) by the same features, and in the smaller
siphuncle and much less parallel septa. The following are its characters :

Uncovered chambers nine ; septary process elongate, acuminate, shallow,
diverging outward from a spiral line joining their bases ; well separated from
the succeeding septa; dorsal portions of the septa short, very excentric as
regards each other; ventral portions opposite them, forming nearly a right
angle with the ventral outline. Siphuncle smnll, more dorsal than the end of
the dorsal fourth of the diameter. Ventral face broad rounded; septal
processes scarcely visible on the ventral view. Diameter of the l*st chamber
o in. 111.; of first visible (at siphuncle) 22 1. Median diameter (from penul-
timate chamber) 8 inches.

This species most resembles Nautilus Parkinsoni, which cannot be far re-
moved from Aturia. In it the septary process approaches closely the succeed-
ing septum ; while in the A. pancifex they fall far short of the latter, and are
more divaricate; the siphuncle is less dorsally situate, measuring one-fourth
the diameter in the former. In A. Agustata, Conrad, from the Eocene of
Oregon, there is much resemblance, but that animal is much more like the zic-
zac ; its septary processes are not divaricate and but little separated; the
dorsal portion of the septary wall instead of being opposite its ventral portions
is opposite that of the septum next anterior. The nearest ally i3 the A.
Mathewsonii Gabb. It appears to differ in the small siphuncle, and obliquely
truncate and divaricate septary processes, and the relatively much shorter
median or central portion of the septary margins. My friend T. A. Conrad's
opinion as to the peculiarities of this species is confirmatory of my own.

Dr. Leidy read several extracts from a letter of Dr. Gideon Lin-
cecura, addressed to Mr. Durand, dated Long Point, Texas, Dec. 24,
1865. One of the extracts related an interesting account of an ant
battle, witnessed by Dr. Lincecum, as follows :

"The large, black tree ants have exceedingly destructive wars sometimes with
their own species. Like the honey bee, they maintain separate and distinct
governments, or hives, and between these, as far as my observation goes, there
is no commerce or intercourse of any description. But they have territorial
claims and quarrels ; and these quarrels are occasionally decided on the battle
field. As they are equal in physical strength and the science of war, the
amount of life that is destroyed in one of their national conflicts is sometimes
very great. I have seen left on one of their battle fields at least a gallon of
the slain. Th*-y were not dead, but they were in a far more lamentable con-
dition. Their legs having been all trimmed off; they lay on the ground amongst
the scattered fragments of their dissevered limbs, wallowing and writhing their
legless bodies, in an agony of sullen, mad, hopeless despair.

This disastrous engagement took place in the little front yard of my office, on
the eveuing of the 10th of July, 1855. There were considerable numbers en-
gaged in battle when I first observed them. They were madly fighting in a
hand to hand conflict, and reinforcements were momentarily arriving to both
armies. The battle had now become general, and was raging over an area of
15 to 20 feet in diameter. It was 4 P. St., and placing a chair in a convenient
situation for observation, I seated myself, for the purpose, if possible, of ascer-
taining the cause of the difficulty, and to note their mode of warfare. I was
not present at the commencing of the battle, and now, while it was wildly
raging, could not find out the cause of it. It was not long, however, until I

[Jan.

NATURAL SCIENCES OF PHILADELPHIA. 5

discovered that the belligerent parties were the subjects of two neighboring-
kingdoms, or hives, each of which, as I could distinguish, by the arrival of
their reinforcements, were coming from two different post-oak trees, which
were standing about fifty yards apart, and the office-yard being very nearly the
half-way ground, afforded me good opportunity to determine that the contend-
ing parlies belonged to distinct communities, and not to the same hive.

The battle continued unabated, until the darkness of the night prevented
further observation. I left them to their fate, with my feelings so highly excited
that I did not rest well that night. Before sunrise the next morning I visited
the battle field, and found it thickly strewed with the legless, hapless warriors, as
described above. There could not have been less than 40,000 left on the ground
who were utterly incapacitated to help themselves. A few of them had a single
leg left. "With this they made shift to pull themselves incessantly around in a
very limited circle. The larger proportion of them lay prost'ate, writhing and
doubling, and vainly straining their agonized, limbless bodies in a stateof mental
■abandonmentand furious desperation. Few were dead. All the dead ona8 that I
saw, did not exceed perhaps a hundred ; and these were found universally in
pairs, mutually grappling each other by the throat. With a few of these pa'rs of
unyielding warriors, life was not entirely extinct. My sympathies being painfnlly
excited, 1 made an effort, where there were signs of vitality, to separate them.
In this ! did not succeed. On closer scrutiny, I found that they had fixed their
caliper-like mandibles in each others throat, and were gripped together with
such inveterate malignity, that they could not be separated without tearing off
their heads.

I had swept them up in a heap, and as the most humane method of curtailing
the wretched condition of the poor, ruined victims of the bloody strife I couid
think of, was making a bole in the ground, with the intention of entombing
the whole of them, Whig and Tory together, and by filling the grave with water,
drown them. But before I had completed ray arrangements, there came a heavy
shower of rain, which soon overwhelmed them with mud and water, thereby
relieving me from the painful task.

It is perhaps nothing amiss to state here, that among the slain — the van-
quished— I saw no type of the species, except the neutrals, or working type.
As on the ensanguined fields of the arrogant genus homo, the conjuring priests
and better bloods of the self-created nobility, after raising the/«*s, had found
it convenient to have business in some safer quarter.

This ant dwells in live trees, in large swarms, or more properly communities,
and feeds principally on insects. On this account he is useful. It is a fortu-
nate thing for any family to have a large tree netr their dwelling that contains
a community of this civil but warlike species of ant.

Near the western corner of my dwel.itig, for eight years, stood a post oik
tree — Quercus obtusiloba — which contained a quite populous community of the
black tree ant in question. During the eight years that the tree survived, it
was the custom of these ants to visit every portion of the house, every night in
warm weather; search out all hidden cracks and crevices, in walls, bedsteads,
and furniture, in fact, travel over every thing about the house, except the
clothing; upon any woven texture they do not travel. In all that eight years,
we had no fleas, bed bugs, or any other insect annoyances. But when the tree
died, \r which they had their home, they went away, and we have missed them
much, as, since their departure, we have been forced to scald and wash out the
house often, to clear it of annoying insects. We should be happy in the ac-
knowledgment of our dependence on the services of another such community.

This species of ant is the largest that is found in Texas. He is quite black,
and disdaining the grovelling habits of the burrowing tribes of the genus, he
constructs his habitation in the live trees. As far as my observation goes,
however, he dwells only in the cedars and post oaks. Very seldom found
in a tree that has been long dead. In the construction of the habitation for the

1866.]

accommodation of the community, be displays a degree of forethonght, skill
and ingenuity, which is arrogantly claimed to belong only to the genus homo.
In the first place, a single female winged ant selects a live tree, in a locality
favorably situated for the peculiar habits of the species, and the growth of the
insects upon which it feeds mainly. She now seeks out some small crevice,
dead limb, or wind crack in the tree, and cutting off her wing3, which are no-
longer useful, but in the way, she commences the work of boriog and chisel-
ing out suitable apartments for the coming community. This she accomplishes-
by cutting away the firm, sound wood of the growing tree, until she has com-
pleted a sufficient number of apartments, or cells, in which to deposit her eggsr
and this ends her labors. Very soon — 12 days — she has produced a swarm of
neutrals, who go to work collecting food and extending the cells to suit the
growing population, until, as I have often witnessed, the inner portion of the
tree will be cut into singularly constructed cells to the extent of 6 or 7 feet,,
without greatly diminishing its strength."

Other extracts from the letter, in relation to certain speeies cf grapes
of Texas, are as follows :

" I am familiar with Buckley's V. monticola, and am pleased that it has
at last been named, and placed in scientific classi6cation. I am not right sure-
that all the Texas grapes have yet been noted. I think it quite probable that
future industry and close scientific scrutiny will deveb pe other species and;
varieties, particularly when the investigator penetrates the valleys and gulches
of our exceeding rough mountain ranges."

" la reference to the Post oak grapes, there are two species here that are-
known among the people as the ' Post oak grape.'1 They are found in the Post
oak lands. The one I sent you flourishes best in the very sandy elevations,
with the bitter- fruited Post oak. This species does not rise exceeding four
or five feet ; it is more of a bush than a vine. The berry is large and sour, but
its odor is very fine. The other species is sometimes found in the same soil,
alongside of the first, but more frequently in better soil, always, however,,
in Post oak lands, which as a general thing, are more or less sandy. This
species is a climbing vine, running over the tops of the trees, bearing heavy
crops of large grapes. These are also too sour for a table grape ; they pro-
duce a very palatable wine, which, very probably, might be greatly improved
by cultivation."

"Mr. G. J. Durham, (my son in-law,) examined your description of the
Vitis monticola to-day. He says Buckley is right about it being the best
American grape, but has never seen such large clusters as you describe ; has
eat of the fruit, which he describes as maturing in September ; that the berry
when ripe, is of a medium siae, bright green, sprinkled with black dots, very
sweet, and that the vine sometimes attains to the height of ten or eleven feet.
It is almost universally found among, and clambering on the rocks, on dry
limestone elevations. That it is not very abundant, &c, all of which I know
to be correct. The other small mountain black grape is more abundant, and is
also quite sweet. It occupies lower grounds than the V. montic(.lar being found
mostly in the heads of the ravines, runniugon the dogwood trees in such quan-
tit es, that he, Durham, has seen them, towards the latter part of September,
when the leaves had all shed off, and in many places where the vines had mat-
ted the tops of the dogwoods, impart a blue caste to the whole scenery, even
at a mile's distance. Companies of soldiers have been known to subsist upon
them alone, two or three days at a time, and no ill results arose from it. This
last grape is called by the people of that country, ' sugar grape,' and is highly
esteemed by all who have a knowledge of it. They will travel a great way at
1he proper season to procure them. The soldiers who are stationed in or near
the mountains will go 30 or 40 miles after them. And yet, I have never heard
of an attempt to domesticate either of the mountain species.

[Jan.

It is at least 150 miles from my place to where they are found in any degree
plenty. The excursions I have made in that direction have always been during
the summer months, consequently I have only seen them in about a half-grown
state. All the mature fruit I have seen were brought by travellers from that
country."

with an example of the same genus from Cape Cod, revealed differences which
must probably be regarded as distinctive of two species. The latter is

prepared and set up. It is a short- finned Megaptera, probably of the species
M. o s p h y i a. Prof. T. has kindly furnished me with the following details as
tj its structure, carefully drawn up by himself.

Length from end of muzzle over convexity of back, forty-three feet nine
inches ; girth about nineteen feet ; length from end of muzzle to axilla (ex-
ternal measurement) fifteen feet; breadth of head across inferior margin of
jaws, eight feet. Length of the pectoral extremity four feet; greatest breadtb
fifteen inches ; they were situated close behind the angle ot the mouth. There
were three hundred and sixty lamiuie of baleen, extending on either side of
the mouth about six feet along the jaw, the longest about eighteen to twenty
inches. The bead was acute. The folds of the throat many and capacious.
The dorsal fin was represented by a conical mass covered by horny integu-
ment, without any membranous appendage, situated well posteriorly. The
body near the tail very slender. Tbe flukes suddenly expand to a breadth of
ten foet. The cervical vertebrae were all distinct. Color: jet black above,,
white on the belly; sides beautifully marbled by the combination of the two
colors.

The most striking feature in this specimen is tbe shortness of the pectoral
limbs, being relatively nearly half less than in the specimen of the o s p h y i a
at Niagara, one- half the length of the cranium, and only one-tenth the total.
This is very different from any of the hitherto known species, and without
doubt distinct.

Dr. Leidy directed the attention of the members to the specimen of a large
phalanx of an extinct reptile, presented this evening by Dr. W. Spillman, of
Columbus, Mississippi. It was derived from the cretaceous formation in the
vicinity of the latter place, and is remarkably well preserved. It is a first
phalanx, and in general form resembles the corresponding phalanges of the
Alligator, but is proportionately more robust. The proximal articular surface
is moderately concave, somewhat uneven ; and in outline is transverse oval
with the lower side flat. The distal extremity is provided with a trochlear
articular surface, and deep pits laterally for ligamentous attachment. The
animalto which the bone belonged is unknown ; it may be conjectured to
have appertained to the fore foot of Hadosaurus. The measurements are as
follows: Length in the axis 5 inches 8 lines ; length laterally ft inches ; trans-
verse diameter of proximal end 2 inches 11 lines ; vertical diameter of do. 2
inches 5 lines; transverse diameter of distal end inferiorly 2 inches 5J lines;
vertical diameter at middle of trochlea 1 inch 6 lines.

Dr. Leidy next directed the attention of the members to a specimen of the
liver of a turkey suspended in alcohol, containing half a dozen cream-colored
tumors, from the size of a pea to that of a nutmeg. The tumors examined
microscopically appear to have the structure of soft cancer, as usually described,
being composed of large nucleated cells in great variety of form. Dr. L.
stated that, after having dined on part of the turkey, on making inquiry for
the missing liver, the cook had given information, that in consequence of the
" white lumps in it, it had not been cooked." On procuring it from the slops,
it was found to be in the condition described. Dr. L. took the opportunity of
expressing the opinion that an unnecessary degree of alarm had been created
in the community in relation to what were considered to be diseased meats,
especially such as are infested with parasites. While he most decidedly re-
commended the avoidance of the flesh of diseased or unwholesome animals,
he thought that all parasites would be destroyed by thorough cooking.

In answer to a question from one of the members, whether he had noticed
Trichina in pork, Dr. L. observed that he had been the first to discover this
parasite in the hog ; the discovery having been made twenty years ago, as may
be seen by referring to the Proceedings of this Academy for October, 1846,
page 107 — 8. This notice had attracted the attention of the German helmin-
thologists, as proved by reference to Diesing's Systema Helminthum, vol. ii.
page 114, and Leuckart, Untersucbungen ii. Trichina spiralis, pages 6, 18.

The circumstances under which the Trichina had been first detected in pork,
was on an occasion when Dr. L. had dined on part of the infested meat. While
eating a slice of pork, he noticed some minute specks, which recalled to mind
the Trichina spots seen in the muscles of a human subject only a few days
previously. Preserving the remainder of the slice, on examination of it mi-
croscopically, he found it full of Trichina spiralis, but the parasites were all
dead from the heat of cooking. In conclusion, Dr. L. observed that all meats
were liable to be infested with parasites, but that there was no danger from
infection if the meats were thoroughly cooked, for he had satisfied himself by
experiment that entozoa are destroyed when submitted to the temperature of
boiling water.

An abundant and well known species, diffused throughout the whole of
temperate North America. It is nearly related to the two species immediately
succeeding, from whicb it is, however, generally not difficult to distinguish,
though all of them much resemble each other whea in young plumage.
Numerous specimens are in the Acad. Museum, and in the Museum Smithsonian
Institution, Washington. Specimens from Yucatan, in the Smithsonian Museum,
have the bill more slender and present some other slight differences, and may
be distinct or referable to A. assimilis, Gundlach.

Numerous specimens in the Academy Museum, and in that of the Smithsonian
Institution. Resembles the preceding but is quite distinct specifically, and can
be distinguished readily by the different red of the shoulders, less rounded tail
and more slender bill, in the present bird. Abundant in the western countries
of North America.

Restricted apparently to the Island of Cuba, but in the adult male much re-
sembling specimens from Yucatan. In this species the female is totally black
in which respect it differs from the two preceding species, though the adult
male is very similar to that of A. phceniceus. The young male resembles the
female, bnt is usually recognizable by the presence of more or less of the scarlet
of the shoulders.

5. Agelaius humeralis, (Vigors.)

Leistes humeralis, Vig. Zool. Jour. iii. p. 442, (1827.)
La Sagra Cuba, Ois. pi. 5.

Now well known as a bird of the Island of Cuba. This species is smaller
than either of the preceding, and not quite strictly of the same subgroup,
having the tail proportionally rather longer and general form apparently more
slender. Common in Cuba. Numerous specimens in the Academy Museum,
and Museum Smithsonian Institution, and in Mr. Lawrence's collection.

In this species the females and young males are stated to be black, (as in A.
assimilis, alsj of Cuba.) A specimen in Mr. Lawrence's collection, which I regard
as a young male of this species, is clear uniform black, the rufous of the shoulder
beginning to appear.

In my judgment this species is properly to be arranged as an Agelaius It
is an abundant bird of the central and western countries of North America,
and specimens are in all collections in this country, though formerly scarce and
highly valued. Straggling specimens, generally of young birds, have occasionally
been obtained in the States on the Atlantic, several having occurred, within
my knowledge, in the vicinity of Philadelphia.

This species does not resemble any other sufficiently intimately to render
close comparison necessary, and can usually be recognized quite readily. It
is handsomely figured by Audubon, and by Bonaparte as above.

mandible. My impression at present is, that this bird is properly to be
arranged here as a subgenus of Agelaius.

Numerous specimens in the Academy Museum. In general appearance and
in the pointed feathers of the head this bird resembles Leistes curaeus (=Curneus
a(errimus) with which it has been sometimes confounded, though much smaller
and not, in my opinion, belonging to the same genus.

Gilliss, U. S. Astr. Exp. Chili, Birds, pi. 16.

Numerous specimens from Chili in the Academy and Smithsonian Institution .
So far as I can see, this bird is an Agelaius, presenting only somewhat greater
attenuation of form than in the more typical species, and in my judgment it is
the type of a subgeneric group quite identical with Neopsar, Sclater. This
species intimately resembles the next succeeding but is larger.

Agelaius xanthocarpus, Bonap. Consp. Av. i. p. 430, (1850.)
"Icterus chilensis, Kittlitz." Bonap. Compt. Rend. 1853, p. 834.

This is a black species with yellow shoulders, much resembling the preceding
(.4. thilius) and apparently to be distinguished mainly by its smaller size. It
is scarcely to be recognized from the Prince Bonaparte's description in Consp.
Av., as cited above, but is clearly indicated by the same distinguished Natural-
ist in Comp. Rend. 1853, p. 833. This bird seems to be constantly smaller
than the preceding, with the bill disproportionately more slender, the wing
shorter and the proportionate lengths of the quills different.

Specimens of this species in the Mus. Smiths. Inst., from Capt. Page's
La Plata Expedition, were obtained at Buenos Ayres and Santa Fe, Argentine
Republic.

An entirely black species, apparently of frequent occurrence in the Island of
Jamaica, from whence numerous specimens have been received at the Smith-
sonian Institution. Specimens in the Academy Museum, also from Jamaica.
Structurally I cannot see that this bird is anything else than an Agelaius, and
of the same subgroup as the preceding. It is more nearly related to the species
immediately succeeding, which is also entirely black, from which, however, it
can readily be distinguished on examination, by its being rather smaller, the
bill more slender and the tarsi shorter, but the most reliable character is the
different color of the plumage at the ba'se of the feathers. In the present bird
the feathers are dark ashy or nearly black at their base, and in the next (.4.
cyanopus,) they are light ashy, abruptly tipped with black. The female in this
bird is stated to be black, in which respect it seems to differ from the suc-
ceeding.

11. Agelaius cyanopus, Vieillot.

Agelaius cyanopus, Vieill. Nouv. Diet, xxxiv. p. 552, (1819.)
This apparently little kaown species is in structura exceedingly like the
species immediately preceding (A. nigerrimus=yeopsar nigerrimus) and the adult
males, at least, of both being glossy black, the general resemblance also is very
strong. In fact, I had always supposed the two to be identical until I had un-
dertaken the present more extended examination, an impression which, though

[March,

NATURAL SCIENCES OP PHILADELPHIA. 13

I have never printed, I may have expressed verbally and epistolatorially, and
beg now to correct, both for myself and others contingently interested.

The males only of the two species are alike in color, the female of the present
species being strictly as described by M. D'Orbigny in Guerin's Magazine,
Zool. 1838, p. 5, and previously by Azara and Vieillot; reddish chestnut,
with longitudinal central stripes of black on the back and dullish yellow on
the under parts of the body. In the Jamaica species {A. nigerrimus) both sexes
are st.ted to be black. The present bird is slightly the larger, with the bill
rather the thicker and the tarsus longer, but the most decisive and reliable
character is that in this species the entire plumage of the body above and
below is light ashy at the bases of the feathers, easily seen in raising them, es-
pecially on the rump and lower part of the back. On those parts, in fact, the
feathers are, almo t throughout their length, light ashy, being only rather
narrowly and abruptly tipped with deep black. In A. nigerrimus this is not
the case, the feathers being, throughout, much darker and in fact nearly black,
widely tipped with deep black. Both birds are strictly of the subgroup
Neopsar.

This bird is accurately described by Azara, Apuntamientos, i. p. 313,
(Walckenaer's French edition, iii. p. 190) whose description is copied by Vieillot,
Nouv. Diet, xxxiv. p. 552. It is also sufficiently described by D'Orbigny,
Guerin's Magazine, Zool. 18C8, Syn. Av. p. 5. The sexes, as given somewhat
provisionally by these authors, are so labelled in the fine collection made by
Mr. Christopher J. Wood, while attached to Capt. Page's Expedition, which
surveyed the Rio La Plata and Rio Parana, which collection is now in the
Museum of the Smithsonian Institution. The female, and probably the young
male, are entirely different from the male in colors, in which respect this species
apparently differs in a singular manner from its near relative, Agelaius or
Neopsar nigerrimus, numerous specimens of which, labelled as both males and
females, are in the collection of the Smithsonian Institution, and are entirely
black. One of M. D'Orbigr.y's specimens in the Academy Museum is probably
that of a young male, but differing only from the female in having the black
stripes of the under parts more numerous and the throat less conspicuously
mottled with black.

This species seems to be of rather wide diffusion, though apparently but in-
differently known to naturalists. Specimens in Academy Museum, labelled
" Bolivia," from M. D'Orbigny's collection, and others received from Mr. John
G. Bell of New York, in " Bogota" collections. Specimens in Capt. Page's
La Plata collection are labelled, undoubtedly correctly, by Mr. Wood, " Para-
guay."

The points of distinction between the two closely allied species here men-
tioned, and especially the infallible character, as I regard it, to be found in
the difference of the colors at the bases of the feathers, I am happy to ac-
knowledge were first pointed out to me by Miss Grace Anna Lewis, most favora-
bly known, and deservedly so, as a lecturer and teacher of Ornithology and
General Natural History. Miss Lewis is one of several accomplished ladies who
have most diligently studied in the Library and Museum of this Academy during
the present winter, and not only successfully, but have contributed also in
the highest degree to the general agreeableness of the similar pursuits of
their fellow students of the stronger sex.

5. Macroagelaius.

2. Agklaius subalaris, (Boissoneau.)

Quiscalus subalaris, Boiss. Rev. Zool. 1840, p. 70.
Specimens in the Academy Museum labelled " Bogota." Though usually
rated as a Quiscalus, this bird, in my opinion, is more properly to be regarded
as an Agelaius, though differing from the typical subgroups in having a longer
and more Quiscalus-like tail. It is not an uncommon bird in collections from
the northern countries of South America.

reliable characters for distinction. Precisely similar specimens from the Rio

tiaries and greater coverts of the wing brownish black, widely tipped and
edged with ferrugineous red. Bill black, feet brown. Sexes very similar,
though the female is less tinged with gray on the head and back.

Total length about 8 inches, wing 3f, tail 3^ inches. Female smaller.

Ilab. — Brazil, Paraguay, Buenos Ayres, Southern Brazil, exclusively?

Having before me two species which to some extent resemble each other, and
both of which 1 suspect are known by the names cited above, I have given this
short description of the bird, which is apparently that described by both
Vieillot and Spix, and figured, rather unsuccessfully, by the latter. The present
species seems to inhabit Southern and South-eastern Brazil, and adjacent
countries, but the only authentic specimens to which I have access are in Capt.
Page's collection, in Smithsonian Museum, and labelled " Buenos Ayres,"'
which locality agrees sufficiently with those authors who have described this
bird.

In this species the tail is black, usually with a tinge of brown, and much
darker than the back, while in the species next described it is much
lighter and exactly of the color sometimes called " hair brown," but little
darker than the upper parts of the body. The quills are red on both webs for
about two- thirds to three-fourths of their length, with the terminal one-third
or one-fourth brownish black. The entire plumage is darker than in the
species immediately succeeding. The description and figures of Spix, cited
above, seem to be clearly from birds of this species, though perhaps not fully
adult. Vieillot describes this species also. I do not regard it as possible that
either this bird or the next succeeding is the young or female of any black
species, as sometimes suspected by authors.

3. Dolichonyx fuscipennis, nobis.

Tail light brown, quills light brown, primaries narrowly edged on their outer
webs, secondaries and tertiaries widely edged on their outer webs, with bright
ferrugineous red. Lores black, which color extends behind the eye, and be-
comes paler. Entire plumage of the head and body light reddish cinereous,
with a tinge of grayish olivaceous on the upper parts, much lighter on the
under parts, and strongly tinged with dull pale ochre yellowish. Greater
coverts of the wings ferrugineous red, with paler edges, which is the color of
the external edges of the wings, (but not of the quills, as in the preceding
species.) Bill and feet brownish black.

Total length about 7 inches, wing 3J, tail 3 inches. Female rather smaller.

Hub. — Cearu, N. E. Brazil. Specimens in Museum Smithsonian Institution,
Washington.

The bird now described is clearly distinct from that immediately preceding,
and is easily distinguished by its lighter and different colors generally, and
especially by its light brown tail, and by its quills being light biown also,
edged only with red. In the preceding the tail is black or brownish black,
and the quills are red on both webs for more than two-thirds of their length,
and brownish black at their ends or terminal one-fourth to one-third.

The only specimens that I have seen of this species are in the collection of
the Smithsonian Institution, and are labelled as male and female, and are
undoubtedly from Cearii, Northern Brazil. This bird and the immediately pre-
ceding D. badius, present some structural characters, which entitle them to be
arranged with nearly equal propriety in either Agelaius or in Dolichonyx, but I
think not in Molothrus*

Oriolus melancholicus, Linn. Syst. Nat. i. p. 180, (1758.)

Edwards' Birds, pi. 85.

Judging from the figure and description of Edwards, I suspect that this is a third species of the
same subgroup of Dolichonyx as D. badius and D. fuscipennis, (above described,) and at present
unknown to naturalists. It is peculiar in having not only the sides of the head, but the throat
dear black, which is not the case in either of the others just mentioned, but otherwise it resem-
bles them. It is stated by Kdwaids to be from the " Spanish West Indies," which now properly
means those islands that were Spanish in 1743.

Gray, Gen. Birds, i. pi. 86.

This is a well known and apparently abundant species of the northern coun-
tries of South America, briefly and by no means sufficiently described by Vie-
illot as above, but very accurately and handsomely figured by G. R. Gray in
his great woik, " The Genera of Birds." The locality given by Vieillot is Cay-
enne, and on that account, in a greater degree than on any peculiar applica-
bility of his description, I am induced to conclude that this is the species en-
titled to the name as above given. The description is short, but, in my opin-
ion, can safely be assumed as intended for this bird.

Head above to near the occiput, and neck before, reddish chestnut or bay
color, which extends and widens on the breast. All other parts of the plu-
mage glossy black. Lores and sides of the head black, which color is restricted
to a very narrow line over the eye. Bill and feet black. Total length about 7
inches.

Hab. — Cayenne; Ceara, Northern Brazil.

Numerous specimens of this species are in the Acad. Mus. and in Mus. Smiths.
Inst. It differs from that immediately succeeding (D. ruficapillus,) in having
the red or bay colors on the head, neck and breast in front much more ex-
tended and ot a different color, reddish chestnut in the present bird, dark chest-
nut in the next succeeding species. The two species are very nearly of the
same size. Both are, in my opinion, most properly to be arranged as a sub-

Agelaius ruficapillus, Vieill., Nouv. Diet., xxxiv. p. 536, (1819.)
Del Corona de canella, Azara, Apuntamientos, i. p. 315, (1802.)

This species is described as from Paraguay, by Azara, whose description is
copied by Vieillot as above, and is, in my opinion, distinct from that immedi-
ately preceding (D. frontalis,) though usually regarded as the same. The only
specimens that I have seen are in Capt. Page's La Plata collection now in the
Mus. Smiths., and are from Paraguay.

In this species the head above and neck before are dark chestnut, and on
both parts that color is more restricted than in the preceding, but especially on
the neck in the present bird, in which it is narrower and does not extend to
the breast. All other parts glossy black, on the sides of the head the black
space is wider over the eye than in the preceding. In a young bird, also in
Page's collection and from the same locality, Paraguay, the chestnut color of
the neck in front is only beginning to appear, but is the same dark chestnut as
in the adult, and quite different in shade from that of the preceding bird.

Although I regard the present and immediately preceding species as differ-
ent, yet if they were the same, the name here given would be entitled to adop-
tion, being the first given by Vieillot, though usually cited erroneously by
authors. In nearly all late works, when the two names A. frontalis and A. ru-
ficapillus are given, the pages cited in Nouv. Diet, are transposed.

Numerous specimens in the Smithsonian Museum, to which I ascribe this

the preceding, but much resembles it in colors and form also, having the same
long wings and proportionate lengths of quills, the first quill being usually
longest. It is smaller and has the bill much more slender ; the wing is shorter
and all other measurements less than those of the preceding well known spe-
cies, except the tail, which is comparatively longer. In colors it is very nearly
the same, but in form it is more slender and smaller, with the tail rather longer.
One specimen from Lower California has the first quill shorter than the second,
but otherwise is quite the same as those from Manzanillo.

.Specimens in the Smithsonian Museum from Yucatan, Costa Rica, and vari-
ous parts of Mexico, and it is evidently an abundant species. Those from Ma-
zatlan and Manzanillo seem to have the bill larger than others, and in some
specimens this is so much the case as to suggest a doubt of specific identity.

This bird presents such very considerable changes in the shades and lustres
of its plumage, that it might readily be mistaken for several species. The adult
has the entire plumage of the head and body of the rich silky metallic yellow-
ish-green, which characterizes the species, the upper and under tail coverts,
wings and tail being lustrous green and blue. Singularly enough, in younger
specimens the back and a large space on the abdomen are fine deep lustrous
blue and violet, having so much the appearance of adult plumage, that series
of specimens are necessary to determine their really intermediate character.
Nearly all specimens brought in collections are of this intermediate description,
and in a younger plumage there is a trace of blue, violet and purple lustre on
nearly the entire plumage. The youngest in the large collection now under
examination are dull brown, with a Taint trace of greenish lustre on the wings
and tail only, and of blue on the back. Forty-two specimens are now before
me, twenty-four of which are from the Smithsonian collections, others are from
the fine collection of my friend Mr. Lawrence, of New York, and in the Acad-
emy Museum. The Academy specimens are from Panama, (Mr. J. G. Bell's.)
Nicaragua, Xalapa, Mazatlan, (Dr. Gambel's,) and various specimens received
from Europe, labelled "Mexico."

NATURAL SCIENCES OP PHILADELPHIA. 19

One specimen in adult plumage kindly lent to me for examination with other
interesting birds of this group, by my friend Mr. Lawrence, of New York.
Another specimen, which I suppose to be this species, is in quite young plumage,
and was received at the Academy in a collection from Demarara. The latter
appears to be younger than those described by Dr. Cabanis in Mus. Hein, as
above.

This species can only be identified from Dr. Cabanis' note in Jour. Orn., 1861,
p. 82, the previous descriptions by him being only applicable to young plu-
mages. It resembles and is allied to the preceding, but is smaller, and the
lustre of the head and body is quite different, being silky yellowish broivn, not
green as in M. seneus. This brown lustre is darker than in the head of M.peco-
ris, but if restricted to the head might readily suggest a comparison with that
species, as is done by Dr. Cabanis in Mus. Hein,, as above. It is a beautiful
species.

Adult. Smaller than M. seneus, bill more slender, wing with the third quill
slightly longest, first shorter, tail rather short. Entire plumage black, the head
and body with a rich silky yellowish- brown lustre 5 upper and under tail coverts,
wings and tail with rich purplish blue and green lustre, the blue prevailing on
the tail coverts and shorter quills. Bill black, feet brownish black.

Total length about 7£ inches, wing 4, tail 2f inches.

Ilab. — Savanilla, New Grenada. Collection of Mr. George N. Lawrence, New
York.

Young? Entire plumage dull brown, lighter on the under parts, and with a
faint trace of green on the wings and tail, and blue on the back. First quill
shorter than the third, and about equal to the fourth. Total length about 6
inches.

Hah. — Demarara. Mus. Acad., Philada.

Mr. Lawrence's specimen is the only adult of this species that I have seen,
and, so far as I know, the only adult specimen known in any collection. It is
a species with very fine rich lustre and perhaps the most handsome bird of this
group.

Specimens, undoubtedly of the bird figured and named as above, are in the
Smithsonian Museum, from the same locality as that given by Buffon, (Buenos
Ayres,) and are peculiarly valuable in the recognition of this species. They
were obtained by the expedition under Capt. T. J. Page, U. S. Navy, which
surveyed the Rivers La Plata and Parana, and are quite reliable in point of local-
ity.

This bird is rather the smallest of four species nearly allied and resembling
each other, which I am about to enumerate. My opinion is that there are at
least this number of species of these nearly related birds, and I suspect that
there are more of which I have only seen immature specimens.

Bill in adult, moderate or rather slender, with the upper mandible narrower
than the under viewed laterally, and slightly curved ; wing long, second quill
longest ; tail moderate or rather short, composed of wide feathers, slightly
rounded at the end.

Plumage black, the entire upper and under parts of head and body having a
uniform purple violet lustre, differing in shade in different specimens, but always
uniform above and below. Shoulders also with purple lustre. Wings and
tail with green lustre, not very brilliant, but easily distinguished ; under tail
coverts also with green lustre. In fine adult specimens there is a tinge of pur-
ple lustre on the wing coverts and on the shortest quills. Bill and feet black.

Total length about 8 inches, wing 4£ to 4J, tail 3\ inches.

About the size of, but scarcely recognizable from Buffon's figure. The spe-
cies is, however, entirely respectable, and entitled, by all the laws of ornitho-
logical genealogy, to bear the name here given. A female or young male
from Buenos Ayres, in Capt. Page's La Plata collection, is nearly uniform dark
grayish fuscous, darker and nearly black on the back, and lighter on the under
parts of the body. Quills and wing coverts edged very distinctly with pale
gray, nearly white on the edges of the quills. Bill and feet black.

Specimens from the Island of Trinidad, and one from Cuba, in the Academy
Museum, seem to be the bird described by both the authors cited above. These
specimens are undoubtedly authentic, the former having been collected under
the direction of Mr. J. G. Bell, of New York, in Trinidad, and most kindly fur-
nished by him for examination, and the specimen from Cuba, collected by the
late Mr. R. C. Taylor of this Academy, in the northern part of that Island,
(Port Gibara, province of Holguin.)

This bird is exceedingly like the preceding, though it is rather larger and
has especially large legs and feet. The color and lustres are nearly the same,
though the present bird seems always to have a large space on the lower abdo-
men, green, uniform with the under tail coverts. My opinion is that it is a
distinct species, though requiring further investigation. I have never seen an
authentic female specimen.

Resembling 31. bonariensis, but larger. Bill rather long, upper mandible
slightly curved, wing long, second quill longest, tail moderate, rounded, feet
strong. Entire plumage black, the head and body above and below with an
uniform purple violet lustre, except on the lower abdomen or ventral region
and the under tail coverts, which have green lustre. Shoulders with purple
lustre. Wings and tail with green lustre not very strong, but very similar to
that of same parts in 31. bonariensis.

Total length 8£ to 9 inches, wing 4j to 4J, tail 3i inches.

Hub. — Trinidad, Cuba, Northern South America? Spec, in Mus. Acad.,

Scarcely to be distinguished from 31. bonariensis, but is larger in all its
measurements, and especially in total length and in the bill and feet. Possibly to
be regarded as a variety of the same species. This bird has not previously
been noticed under any name, to my knowledge, from the island of Cuba.

Specimens from Callao, Peru, collected by the late Dr. Gambel, others
labelled as from Callao and Lima, and others labelled " Mexico " in Acad.
Museum. This is a species about the size of the two preceding, but readily
distinguished from them by its large strong bill, and the golden yellowish-
purple lustre of the under parts of the body. It is a clearly distinct species,
and appears to be the bird figured by Habn, as above cited, whose figure is
rather too short, but in form generally, and especially the thick strong
bill, and the color of the upper parts, is a fair representation. The immature
plumage is entirely different from that of either of the preceding.

Rather larger than 31. bonariensis, and about the size of 31. discolor, and
easily distinguished by its stronger bill and the golden purple lustre of the
plumage of the under parts of tbe body. Bill rather long, strong upper man-
dible slightly curved, wing long, with the third quill longest, tail moderate,
not so much rounded as in the preceding species.

Entire plumage black, head above and upper parts of body with a violet

purple lustre, under parts with a rich golden purple lustre, most conspicuous
on the breast and neck in front ; under tail coverts with green lustre. Shoulders
purple, wings and tail with green lustre.

Total length about 8 to 8} inches, wing 4\ to 4|, tail 3\ to 3£ inches.

Young. General colors "light yellowish and dull brown, much like young
Plocei or Xanlhorni. Upper parts dull light brown, plumage edged with dull
yellow, under parts pale dull yellow, with longitudinal stripes of pale brown.
Bill very strong.

Specimens from Bahia, from which locality this bird is commonly brought,
and is apparently the common species of Eastern South America. Rather
larger than, but difficult to distinguish from, the species immediately preced-
ing, (M. purpurascens,) and has the same golden purple lustre on the plumage
of the under parts of the body. The bill is straighter, and not so strong, and
the second and third quills nearly equal.

Though commonly brought from Bahia in collections, I have not a sufficient
aumber of specimens in adult plumage for a satisfactory examination of th'S
bird, though I am inclined to the opinion that it is not quite identical with
either of the preceding. Specimens that I regard as M. brevirostris appear to
me to be the same as others also from Bahia, which I regard as M. sericeus,
probably differing only in age. This seems to be rather the largest species of
this group, though, perhaps, little larger than M. seneus or M. purpurascens, and,
though my opinion is favorable, I am under the necessity of regarding it as a
species of but imperfect respectability. It is certainly, I think, the bird
described by Swainson, as above, and probably also by Lichtenstein under the
same name.

D'Orb. Voy. Am. Mer. Ois., pi. 52, fig. 3.

Two specimens from M. D'Orbigny's collection are in the Academy Museum.
This curious bird, in color and general characters, intimately resembles the
last four species above given, but also much resembles the birds of the group
Lampropsar. Of the species here given as Molothri, it approaches most
closely M. bonariensis and M. discolor, and has the lustres of the plumage very
similar, but is larger than either, and, in fact, is rather larger and with longer
wings than either of the preceding species in this memoir. It is, in my judg-
ment, entirely a peculiar bird, and described, entirely judiciously, by the dis-
tinguished authors above cited as a distinct species.

The peculiar character of this bird is the singular lobe on the cutting edge
of the upper mandible, as stated by M. D'Orbigny, near the point, and which,
if met with in a single specimen, might readily be suspected of being a
deformity, as intimated by the greatest of European Ornithologists now living:
" rostro deformi?" This suspicion and general view of the case is, however, to
me rendered less cogent by the fact that I have before me two of M. D'Orbigny's
specimens, and they are like each other with much exactness ! In both the
adult specimens, this curious lobe is more strongly developed than as repre-
sented in M. D'Orbigny's figure above cited.

This bird is accurately described by M. D'Orbigny, as above cited, and also

in Voy. Am. Mer. Ois., p. 36?. It is with doubt that I arrange this bird as
representing a subgroup, and am not without a suspicion that it is more
properly to be placed in the group Lampropsar. The only specimens that I
have seen are those of M. D'Orbigny, above alluded to, and this species seems
to be little known to naturalists.

The smallest of several species of this genus, and brought abundantly io
collections from Brazil. In the various specimens now before me, this bird
presents a uniform purplish blue lustre, by which it can be easily distinguished
from either of the two species immediately succeeding. It has not quite the
fine purple and violet lustre of either of them. Numerous speeimens in the
Academy Museum.

11. Molothktjs gcianenbis, (Cabanis).

Lampropsar guianensis, Cab. Schombg. Guiana, iii. p. 682, (1848).

than the preceding, with the wing rather shorter, comparatively, and third
quill slightly longest. In the specimens before me, this species is easily dis-
tinguished from the preceding by the violet purple lustre of the head and of the
upper and under parts of the body. Wings and tail with greenish lustre,
darker than in the preceding. In colors, this species resembles the nest suc-
ceeding, though scarcely more than half the size. It appears to be from
Northern South America.

Specimens of this species are in the Academy Museum, and in the collection
of that distinguished and excellent Ornithologist, Mr. George N. Lawrence, of
New York.

12. Molothrus Cabanisii, nobis.

Lampropsar dives, Cab. Mus. Hein., p. 194? (nee Bonap.)

though of the same general form as in both the preceding. Entire plumage
black, head and body, above and below, with a fine violet purple lustre, and
having a golden tinge on the under parts. Wings and tail with a dark green
lustre, bill and feet black, claws ratber long and slender, but very sharp.

Easily distinguished from the two preceding species by its much larger size,
and, in the specimens now at my disposal, the plumage is the most lustrous,
the golden violet purple in the present bird being especially a distinguishable
feature. I am not confident that this is the bird alluded to by Dr. Cabanis as
Lampropsar dives, as above cited, but regard it as probable. It is smaller than,
and generically distinct from the bird which seems to be L. dives, Bonap.

To this handsome species I have taken the liberty of applying the name of my
excellent friend and correspondent, Dr. Cabanis, of Berlin, not so much

Uue specimen only of this curious bird is in the Museum of the Smithsonian

such highly lustrous plumage as either of the preceding. It is apparently
quite adult, and easily recognized by the reddish che3tnut-colored axillary
feathers, to be seen at once by raising the wing at the shoulder.

Though having all the characters of an adult bird, the plumage in this
specimen has but slight lustre, inclining to bluish purple on the head and
body, and greenish on the wings and tail. The only specimen that 1 have

An abundant bird of Eastern North America, carefully described by the
authors cited above, and by Prof. Baird in Birds of N. A. p. 535, and accu-
rately figured as above given. The specific name " magna," has undoubted
priority for this species, and I only object to it and do not use it at present on
account of its singular inappropriateness to this bird as a species of the genu9
Sturnella or Little Stare. Sturnella magna, or Great Little Stare, strikes me as
approaching absurdity, if that is possible, or any fault in ornithological nomen-
clature ! I will in no wise molest scientific persons whose tastes may be differ-
ent in this matter, however, and so promise.

This bird is nearly related to all of the next four species of this genus,
equally in structure and in colors, and it would be difficult to describe by
positive characters either spf-cies of this group, so as to insure recognition
absolutely, or without comparative characters being given. All the species
can be identified from the excellent descriptions in Ibis, 1861, p. 179, by Dr.
Sclater of London, and the best descriptions of the two species of the United
States are by Prof. Baird in Birds of N. A. p. 535. No other genus or sub-
genus of this family presents so many spec:es of such uniformity of structure
and similarity of colors, and there are, assuredly, few such in the entire king-

colored than the preceding, and with the transverse markings of the upper
parts narrower, and, as pointed out by Prof. Baird, (B. of N. A. p. 538), the
yellow of the throat seems generally to extend around under the eye and at
the base of the under mandible in this bird more than in S. ludovieiana. The
two species are about the same size.

Numerous specimens in the Academy Museum and in the Museum Smithso-
nian Institution. In the central regions of North America it is possible that a
hybrid race between the two species may be produced, to be referred with
about equal propriety to either. Usually, and having some degree of experi-
ence with these two species, it is not difficult to distinguish them at sight,
though such consummation to be surely brought about, would require elabo-
rate descriptions in words.

:!. Stursella hippocrepis, Wagler.

Sturnella hippocrepis, Wagl. Isis, 1832, p. '281.

Smaller than either of the preceding, and having the pectoral black collar
much more narrow. This species is very nearly related to the next succeed-
ing (S. mexicana,) and can scarcely be distinguished from it by any characters
which seem to be reliable. It is, howerer, in my opinion, clearly distinct from
S. ludovieiana and S. neglec/a, and all the characters are present in the speci-
mens before me, which are stated with his usual great clearness and accuracy
by Mr. Lawrence, in an interesting memoir on the birds of Cuba, in Annate
N. Y. Lyceum, vii. p. 266. In the present species the tertiaries are nearly or
quite equal in length to the primaries, while in S. ludovieianus they are much
shorter, which character is especially stated by Mr. Lawrence and seems to be
quite correct.

Numerous specimen? from Cuba are in the Museum Smithsonian Institution,
and this bird seems to be peculiar to that island. The peculiarities pointed
out by Mr. Lawrence stand good in all specimens of this bird now under
examination.

4. Sturnella mexicana Sclater.

Sturnella mexicana, Sclat. Ibis, 1861, p. 79.
Very nearly related to the preceding, (S. hippocrepis,} if distinct, and I give
it, at present, as a species provisionally only. Smaller than 5. ludovieiana and

5. neglccta, but perhaps rather more closely resembling the latter in colors.
Pectoral black collar narrow. The colors of the upper parts seem to be less
clearly defined, and of a slightly different style and pattern from the preceding,
and it may bear about the same relation to that species (S. hippocrepis} that
5. neglecta does to &. ludovieiana. Such relation I hold to be rather probable
from the specimens now at hand.

Specimens from Mexico in Academy Museum, and in Museum Smithsonian
Institution from Mexico and Guatemala.

5. Sturnella meridionals, Sclater.

Sturnella meridionalis, Sclat. Ibis, 1861, p. 79.

claws, bill longer and more pointed. Black pectoral collar narrow as in

5. hippocrepis and S. mexicana, but with tertiaries short as in S. ludovieiana.
One specimen from Brazil, in Museum Smithsonian, and others of doubtful

locality, but South American, in Museum Academy. This species seems to be

and breast, not extending on the abdomen as in the preceding. One fine ap-
parently adult specimen now before me has the tibise clear white on their inner
surfaces, mottled with black on their outer, in which plumage it seems to be
Leistes albipes, Philip, et Landb., as above cited. The under wing coverts are
white, as in the preceding.

The synonymy of this species I find to be difficult, but it is not improbable
that it was first described by Dr. Cabanis as above cited, authors to the con-
trary notwithstanding. Specimens in Mus. Acad.

Numerous specimens of this apparently common species are in the Academy
Museum from Brazil. Easily recognized when adult, by its brilliant scarlet
head, and tibiae and black body. The young is nearly uniform dull black, the
scarlet generally first appearing on the throat and forehead.

This species ends the subfamily Agelaiinae, but I am not quite confident
that the genera or subgenera Creadion, Vieillot, and Amblycercus, Cabanis, do
not belong here. Such may be the case also with Hypopyrrhus, Bonaparte.
At present, however, my impression is, that all of these have greater affinities
in other groups of the family Icteridce.

tiona, though presenting considerable diversity in coloration. The genus
Adamas'or which has been placed among the Fulmars by Bonaparte, seems,
as I have attempted to show in a previous paper,* to fall mo -t naturally among
the Puffin fee ; being not widely separable from Majaqueus, which Bonaparte hini-
se'f (C«ms;). Av. ii. p. 200) places among the Shearwaters. The position of the
somewhat anomalous genus Daption is a little uncertain ; possessing, as it
does, some of the characteristics of the present group. I am of opinion, however,
that it is most naturally to be included with the sEstrelatece, uuder which
section I shall hereafter consider it.

The section Fulmar e<e then, as thus constituted, is composed of large or
moderate sized species, having a form very stout, compact, and robust, and
being nearly always very light colored. It is apparently the section of Petrels
most closely allied to the Laride, and forming the connecting link between
the two families. Particularly in the genus Tkalassoica U the Laridine
aspect very marked.

The bill is always large and robust. The unguis of the upper mandible
is strong, very convex in profile, and much hooked at the extremity. That of the
lower mandible is never much attenuated nor decurved, with the outline of
the gonys decidedly concave ; hut is short, stout, obtuse, with a straight as-
cending gonys. The nasal tubes are prominent, wide, long, vertically truu-
cated, usually emarginated at their end ; the nasal septum very thin and deli-
cate. The wings are of mo lerate length, reaching when folded about to the end
of the tail ; the primaries are very broad. The tail is short ; more or less
rounded ; of 14 to 16 feathers, all of which are broad and subtruncated at their
extremities. The feet are comparatively small and weak. The tarsus is
slender, compressed, reticulated, shorter than the middle toe. The outer toe
is as long or longer than the middle one. The tip of the inner claw about
reaches to the base of the middle.

Of the three genera which I regard as the components of this section, Ossi-
fraga has 16 rectrices, while Fulmarus and Tkalassoica have but 14. Of Ful-
marus we at present know three species ; of Tkalassoica, two ; while Ossifraga
has but a single representative. The section is cosmopolitan.

Large in size, and very robust in form. Colors white and light pearl blue,
with darker primaries.

As above defined, the genus Fulmarus is restricted to its type glacialis,
and tlie two other closely allied species pacificus and Itodgersii.

As is the case with all the genera of the family, the name Procellaria has
been applied to the present genus. As I have already indicated,* I consider P.
pelagica and its congeners as typical of the genus Procellaria. Fulmarus appears
to be the first distinctive appellation of the present group ; having priority
over Rhantistes of Kaup.

The type of this genus is subject to variations in size, etc., remarkable even
in this variable family. In consequence, several races or varieties have been
described aud named ; which I think are properly to be included under glaci-
alis. 1 recognize as valid the three following species.

This species has served as the basis of so many nominal species, caused by
its great variations, that, although no description of it is needed, it may bo
well to notice the differences to be found whenever large series are compared.

Examination of numerous specimens convinces me that the differences in
color are those of age and season chiefly if not wholly ; since the species passes
very gradually from the uniform dull greyish brown of youth to the pure white
and pearly blue of the adult condition. There do not seem to be any very
well defined stages during this transition. Birds of the year, before the autum-
nal moult, are entirely fuliginous gray, lighter beneath, with darker margins to
the feathers of the back and wing coverts. The tail is about concolor with
the rest of the plumage. There is an angular anteocular black spot. The bill
and feet are of a dull yellowish or ashy brown. After the moult, the pearly
blue of the back extends upon the nape and head ; (just as it does in Rissa
tridactyla ;) and the upper tail coverts, and the rectrices are of the same color.
The primaries are colored the same as in the mature bird. Spring and summer
adults have the pearl blue restricted to the back and wing coverts ; other parts
of the body being pure white. The distribution of colors is then just as in
Larus canus, argentatus, etc. The dark anteocular spot however seems perma-
nent. The bill is wholly yellow ; the feet yellow with a bluish tint.

The variations in size are carefully to be noted ; since, taken in connection
with a varying length and robustness of bill, they have given rise to nominal
species. The average length appears to be about 16'5 inches; there is how-
ever a margin of one or even two inches both above and below this standard
to be allowed. The wing measures from the carpal joint to the tip of the
longest primary, from rather less than 11 to 12-5 inches. The average length
of the bill (chord of the culnien) is 1*5 ; but it may be l-33 or 1-66, with a
corresponding difference in robustness. Young birds are always weak-billed.
The tail ranges from about 4 to about 5 inches. The average of the tarsus is
about 2 inches : of the middle toe without its claw, 2*25 ; both varying to
the extent of a fourth of an inch or rather more. The feet however as a general
rule differ less in dimensions than other parts.

The synonomy of this species is very brief and uninvolved ; the points re-

quiring considerations being hardly more than those relating to the varieties
or supposed species which have been separated from it.

I have before me a rather small and weak-billed specimenfrom Greenland,
which appears to be an example of what was called P. minor by Kjserb, or P.
glacialis var. viinor by Bonaparte. It has no claim that I can discover to be
considered as even a variety ; as the difference in size from the ordinary
standard is by no means uusual. In the var. Audubonii of Bonaparte — based
upon the bird used for the figures in Audubon's works — there is exhibited a by
no means unusual variation in size, or in strength of bill.

While I would thus consider the Atlantic Fulmars as representing but a
single species, nothing that I have found in an extensive series tends to invali-
date the claims of F. pacijicus to specific distinction.

? Procellaria glacialis (juniores), Kuhl, Beit. Zool., 1823, p. 141.

This species, though very closely allied to glacialis, and requiring a rather
careful comparison to distinguish it, yet appears to differ by constant char-
acters. It is nearly or quite as large as that species ; but the feet are, per-
haps, a little shorter and weaker. There seems to be a constant difference in
the shape of the bill ; which, though not much shorter, is considerably
weaker, more compressed, and more attenuated and decurved at the tip. The
inferior mandibular rami divaricate at a more acute angle. But I have not
been able, in examining quite a large series, among which is one of Audu-
bon's types, to find any distinctive characters in the nasal tubes ; the dorsal
outline of which does not appear to be straighter than that of the Atlantic
bird. In fact, one example of pacificus has a more concave tube than one of
glacialis, now before me ; nor can I discover that the carination of the tubes
is more marked in one species than in the other. One example of pacificus
shows no trace of any carination.

Some features of coloration are, perhaps, most distinctive of this species.
The upper parts are much darker in pacificus than in glacialis ; inclining to a
bluish cinereous rather than a pearly blue. The rump and upper tail
coverts, in lieu of being nearly pure white, are concolor with the middle of
the back, or even darker than it. The bend of the wing, and the secondaries
and tertials are somewhat deeper-colored than those of glacialis. The bill is
bright yellow, lightest on the unguis ; the root of which latter is bluish
horn-colored. The feet are bright yellow, only slightly obscured on the
outer aspect of the tarsus, and on the outer toe. The anteocular spot is
smaller and more indistinctly marked than in glacialis.

Young birds have the yellow of the bill obscured by brownish or greenish,
the unguis especially being quite dark, as are also the feet and toes. The
entire plumage is fuliginous grayish brown ; deepest on the side of the head ;
lighter on the under parts of the body, where there is considerable of a smoky
cinereous tint. Most of the feathers of the upper parts have cinereous or
pearly tips. Some of the tertials are more or less distinctly tipped with
grayish white. The remiges and rectrices are brownish black ; the former
lightest, inclining towards their tips to grayish. The primary shafts are
light brown, deepening in color at their apices. The under surfaces of the
primaries are cinereous gray.

I thus detail the differences I have been able to find between the two sup-
posed species, considering them as sufficient to establish a species ; though

[March,

with equal reason they might be held as indicative of the extreme of varia-
tion of a single changeable type, and thus forming only a local race or geo-
graphical variety.

The Procellaria glacialis of Pallas in all probabilty refers to this species
rather than to the'true glacialis of Linnaeus. I also think that the "Procel-
laria glacialis, juniores ex America Septentrionali allatre, colore cineraseenti-
fuliginoso tincta) " of Kuhl's "Beitrage," p. 141, belongs here rather than to
the Thalassoica glacialoides to which Dr. Schlegel has referred it.

I have before me Mr. Cassin's original and type specimen. With exactly
the size and very nearly the form of F. glacialis, it differs from the latter
very decidedly in color, as will be seen by the following comparative de-
scription :

The bill is bright yellow, except the base of the unguis of the upper man-
dible, which is bluish black. The middle of the back, the scapular feathers
and some of the lesser wing coverts are a rather dark grayish ash, approach-
ing the hue that is most distinctive of pacijicus. The rump and upper tail
coverts are pure white. The rectrices are fuliginous grayish ash ; their inner
webs and their extreme apices whitish, their shafts wholly yellowish. The
whole of the tertials and the greater wing coverts are pure white ; the lesser
wing coverts and edge of the wing of the same color, but marbled with the
ashy hue of the back. The secondaries are white with yellow shafts; the
terminal half of their outer webs grayish brown. The primaries are dull
brownish black, their entire shafts yellow, their inner webs to within an
inch of their tips white. These markings of the primaries are much like
those of Thalassoica glacialoides. All the rest of the body is white. The
legs and feet are bright yellow ; the outer aspect of the tarsus, aud the outer
toe somewhat obscured by dusky. The nails are ochraceous brown.

Bill along chord of culmen 1*50 inches and hundredths ; from feathers on side
of lower mandible to its apex 140; nasal tubes *60 ; height of bill at base *80 ;
width about the same ; wing from the carpus 1225 ; tail 5*50 ; exterior
rectrices -75 shorter; tarsus 2-00 ; middle toe and claw 2-60 ; inner do. 220.
Some differences in the shape of the bill of this species are readily recog-
nizable. It is even stouter than that of glacialis, being at the base fully aa
wide as high ; and the lateral lamina? of the upper mandible is bulging and
convex rather than straight. The nasal tubes are larger, broader, more
depressed, with no traces of median longitudinal carination. Independently
of these discrepancies, it is to be distinguished from glacialis by the restric-
tion in extent and deep hue of the color of the back ; by the white tertials
and coverts, dark rectrices, yellow primary shafts, amount of white on inner
webs of primaries, etc.

long as the inner toe without the claw ; about three-fifths the middle toe.
Wings and tail as in Fulmariis.

This genus differs from Fulmarus in little except the bill ; in which, how-
ever, the distinction is well marked. The bill has, notwithstanding the
presence of the nasal tube?, an aspect which is Laridine to a degree not
found in any other genus of the family ; and the pattern of coloration in the
type of the genus is almost precisely that of a Larus.

Two species are known to compose the genus. Intimately allied in form,
thair colors are more widely diverse than is usually found to be the case in
congeners of this family.

The sulci on the 6ides of the bill, uniting the lateral laminae with the un-
guis, are remarkably narrow, shallow, and indistinct ; and the bill in other
respects calls forcibly to mind that of a small Larus argentatus. The colors of
the back, and of the primaries even to the white spaces on their inner webs,
and the size and shape of the feet and tail are rather those of a Laridine than
& Procellaridine bird.

Nasal tubes a third the length of the culmen, basally broad and depressed :
terminally narrower and elevated ; their dorsal outline concave, subcarinated,
their tip deeply emarginated ; nasal septum very thin, and so short as not to
reach the end of the nasal tube. Culmen flattened from tube to unguis ; latter
much elevated and very convex. Shape of lower mandible that of Larus.
Tarsus much compressed, shorter than middle toe without its claw ; hardly
exceeding the inner toe alone. Outer toe without its claw longer than the
middle. Folded wings reach to end of tail. Primaries broad, tapering rather
suddenly to their rounded apices. Tail contained 1\ times in the wing from
the carpal joint.

Bill yellow ; nasal tube, unguis and sometimes basal portion of superior
lateral mandibular laminae, bluish horn. Feet yellow. Upper parts uniform
clear pearl blue ; exactly the shade that obtains in some species of Larus.
This color begins as a faint wash or shading on the nape, deepening as it pro-
ceeds backwards until on the interscapular region it has gained its full inten-
sity ; which continues undiminished over the whole back, rump, wing coverts,
tertials and tail coverts, to the tips of the rectrices themselves. The feathers
just along the edge of the wing, however, are grayish slate. Primaries black,

[March,

their shafts yellowish white at the base, changing to black towards their apices ;
their inner webs pearly white near their tips. This white on the first primary
extends to within two inches of the tip ; on the rest successively extends nearer
the tip of each, till on the innermost it occupies the whole web. Secondaries
slaty black on their outer, white on their inner webs. Elsewhere the bird is
pure white ; except a small anteocular dusky spot ; and a faint shade of pearl
gray on the sides of the breast and body, and on the flanks.

Dimensions. Length 18 to 19 inches, extent of wings about 36. Bill along
culuien 2, from feathers on side of lower mandible l-75 ; its height or width
at base '70; nasal tubes *66. Wing from the carpus 13. Tail 5-25. Tarsus 2 ;
middle toe and claw 2*60 ; outer 2-70 ; inner 2*25.

There is no other species towards which the present bears an intimate re-
semblance. Th. antarctica is exceedingly dissimilar in color, though so nearly
the same in form. The generic peculiarities — especiallyof the bill — of Fuhna-
rus glacialis er pacificus at once distinguish the latter.

Synonymy. The Proc. glacialis of Forster's Descriptiones Animalium is un-
doubtedly this species. The expressions regarding the nasal tube — " coerules-
cens in rostro incarnato,*— apice uigro"; and regarding the primaries — " fusco-
nigrae, margine interiore albido, " are quite inconsistent with the true glacialis.
This is the only instance I have met with of the application of the name " gla-
cialis " to this species.

The Procellaria tenuirostris Audubon is most certainly this species. I have
compared Audubon's type specimen with specimens of undoubted ghcialoides
from various localities. Mr. Cassin has shown (U. S. Expl. Exp. 1858, Birds,
p. 409) that possibly Audubon's designation lias priority over that of timith.

I do not suppose that the var. polaris of Bonaparte's Couspectus is in any
way diverse fr- m the true glacialoides.

I hardly know upon what grounds Dr. Schlegel has laid aside the prior names
of this species to give it the appellation " JSmithi."

In this species there is the same general character of the nasal tube as in
T. glacialoides ; though it is comparatively a little broader and shorter, and
somewhat less carinated on the median dorsal line. The sulci uniting the
different laminae of the bill are ratber deeper and more distinct, taking away
something of the Laridine aspect, so marked in the other species. The lateral
rostral lamina is wider at its base, and tapers more rapidly to the acute apex
by which it is united to the unguis. The tip of the lower mandible is more
decurved, and the gonys is a little concave.

The coloration of this species is so peculiar, and so widely dissimilar from
any other Procellaridian, that it is needless to give any description here. The
species has I believe no important synonyms.

The species is found in quiie diverse states of plumage. The upper parts are
of a varying shade of brown, and more or less mottled with dull white, the
edges and tips of many of the feathers being thus colored. Often however there
are no traces of this white mottling, and the dorsal plumage is of a uniform
sombre fuliginous. The wings and tail seem to be nearly always plain dark
brown. In adult birds the under parts, and a portion of the neck in front are
white. The amount of this white varies with age ; and young or immature
birds have the whole under parts similarly colored with the rest of the body ;
though tiie hue is usually rather lighter and duller. The gradations in color
between old and young are very gradual ; scarcely any two specimens, not
perfectly mature, being found exactly alike. The feet of some specimens are
yellowish, more or less obscured by dusky ; of others are uniform fuliginous
brownish black. The bill is yellow in all the specimens I have seen. As a re-
markable state of plumage which I do not recollect to have seen given, I may in-
stance a specimen in the Philadelphia Academy, which is pure white, all over,

• But its length seems liable to Home c msiier.ible variation. I believe it always extends nearly
or quite to the root of the ungu.s.

even to the wings and tail ; the continuity of the white only interrupted by a
few isolated brown feathers sparsely scattered at irregular intervals over the
body. Other specimens in the Academy Museum are in very nearly the
plumage described by Gmelin and Latham as P. Brasiliana ; so that there can
be little doubt of the propriety of referring the latter to tbis species.*

The species and genera treated of in this paper are so few and so well known
that an analytical synopsis does not seem to be required.

Description of twelve new species of TJNIONIDJi: from South America.

BY ISAAC LEA.

The species described and figured in this paper were procured in South
America by Don Patricio M. Paz, of Madrid, and very obligingly submitted to
me. Some of them fortunately were in alcohol, thus preserving the soft pans,
which are of great interest. These have been carefully examined and described,
and it will be observed that the South American characteristics of the outer
hard parts, as well as the included soft parts, which seem to pertain to the
Uniones of that continent, are here exhibited. I allude more particularly to the
round palpi, or mouth lips, and the divergent folds of the tips of the beaks, neither
of which have I observed in our North American species. Very little atten-
tion, heretofore, has been given to the soft parts of the Unionidce of South
America, and none to the embryonic shell, except by myself. M. d'Orbigny, in his
Voyage dans V Amerique 3Ieridional, has imperfectly described and figured the
soft parts of some of the genera. Spix, in his Testacea Fluviatilia Braziliensia,.
takes no notice of the soft parts of the species, which he describes and figures
with much accuracy.

Unio pecdliaris. — Testa laevi, quadrata, compressiuscula, ina?quilaterali,
postice obtuse angulata, antice rotunda : valvulis crassiusculis, antice aliquantc
crassioribus ; natibus subprominentibus, ad apices divaricati uudulatis ; epi-
detmide virido-fusca, eradiata; demibuscardinalibus parviusculis, compressis,
obliquis, in utroque valvulo duplicibus ; lateralibus longis, lamellatis curvis-
que ; margarita crerul -o-alba et iridescente.

Embryonic Shell subtriangular, light brown ; dorsal line rather long and
straight ; side margins irregular and unequal — one being a segment of a
circle, the other an irregular curve line — forming an obtuse angle at the base ::
basal margin obtusely angular and furnished with hooks ; granulate over the
whole surface.

This very peculiar and unique form is now for the first time observed. Its-
unequal lateral margins give it an abnormal and lapsided appearance, totally
differing in this from any other species known to me.

Bes Naturforschee.

A Journal for Natural History^ edited by J. C. D, Schreber and J. E. J. Walck,

" Der Naturforscher " was published at Halle from the year 1774 to 1804,
that is to say, during a period of thirty years, one part or volume every year,
though it is usually bound in fifteen volumes, octavo. Each of the thirty parts
is, however, separately paged and has a title page and date of its own, and must
be considered and treated as a volume for all practical purposes. The first thir-
teen volumes are edited by Walch, the last seventeen by Schreber, both of whom
■are contributors of a large number of papers in various departments of the Zoo-
logical and Botanical Sciences. In Zoology the papers of both are mainly on
groups of the Invertebrata, but the latter occasionally has a valuable article on
other subjects and higher orders of animals, and is the eminent and successful
author of sta«dard and elaborate work3 on Mammalogy.

The illustrations in this Journal are generally very superior, many of the
colored plates, of Insects and Shells especially, being much above the average
of those of a similar description to be found in books of the last century, and
all of them seem to be quite sufficient for the easy recognition of species.
There are about one hundred and fifty plates in the series, nearly all of which
are carefully colored, those of Insects being the most numerous, but of Shells,
also, there are a very considerable number. Special allusion will be made to
the plates of Birds towards the end of this paper. Of the contents of the en-
tire work as published, Indices and " Registers" are given at the end of every
tenth volume, apparently very copious and accurate, and from which it appears
that no less than sis hundred and four memoirs in all departments of Natural
History are contained in these thirty volumes. In Ornithology the contribu-
tions are not numerous, and contain but few descriptions of species, but of those
few descriptions, nearly all the names proposed would stand good were it not
for the recently exhumed names of Prof. P. L. S. Miiller. The authors of these
contributions are, for the greater part, quite unknowa in modern times as or-
nithological writers.

" Der Naturforscher " seems to have been a very considerable journal in its
day, and names amongst its contributors many naturalists of standard and de-
servedly 'nigh reputation. The memoirs on Conchological and Entomological
subjects are apparently the most valuable, and are certainly the most numerous
and most carefully illustrated. For better or worse it happens that compara-
tively few of its many papers are devoted to Ornithology, and a large majority

of those are of a general or local character, relating mainly to European birds,
though several of them are highly interesting. In the entire series of .thirty
volumes, there are on'y seven descriptions of species presumed to have been
previously unknown, and which we give in a succeeding page of this article ;
and, also, we propose to give an inventory or general reckoning of the entire
ornithological contents of this periodical, not premising in the least that it is
either an extended or difficult enterprise. But as we have frequently seen this
Journal cited by the older authors, and even occasionally in books of recent
formation, (mostly conglomerate,) we have looked up these ornithological ar-
• tides to the end that hereafter they shall be seen truly, not only by ourselves,
but also by such others who, like us, may have found out that there i3 a differ-
ence between hearing and believing, and even between looking and seeing1.
Any one can look, but comparatively few, see, and, at least, light shall no longer
be wanting on " Der Naturforscher."

The words of our choice text for this interesting occasion, beloved brethren,
we shall not dwell upon nor enlarge upon, even not so much as might conduce
to solid profit in a moral sense; both somewhat of time and inclination being
wanting, and an homily, fortunately perhaps, not necessary. Who has suffered,
beloved, not for his fault, but thine ? And in the vast affluence of the field of
study and solid acquirement spread before thee, not only in the libraries and
museums established by the governments of all civilized nations, but in our
own times, in the countries of our native language and by our own contempo-
raries, such high souled and ever memorable men as Thomas B. Wilson and
Henry Bryant, John Henry Gurney and Osbert Salvin, art thou indeed but a
siarvling? We wait not for answer, but proceed about our business with some
soberness of thought, (and with recommendatory suggestion.)

Here follows a list of all the memoirs relating to Ornithology in this Journal,
and, at the end of that, a list of the species of Birds therein described, as cer-
tainly intended and supposed by the authors (but generally erroneously,) for
the first time.

List of the BIRDS of Fort Whipple, Arizona : with which are incorporated

all other species ascertained to inhahit the Territory ; with brief

critical and field Notes, descriptions of new species, etc.

BY ELLIOTT COUES, A. M., M. D.
(Assistant Surgeon U. S. Army.)

The Territory of Arizona comprises that portion of what was formerly the
vast Territory of New Mexico lying west of the 109th meridian; together with
an extensive tract obtained from Mexico, known as the " Gadsden purchase."
As at present bounded, Utah and Nevada form its northern limit, while its
southern border is contiguous in its whole extent to the Mexican State of
Sonora. The Colorado River separates the greater portion of its western
border from California ; the extreme southwestern corner of the Territory
being at the junction of the Gila with the Colorado River.

The extensive area thus bounded, constitutes, in connection with New Mex-
ico, what is known, in relation to its Faunal characteristics, as the " South-
ern Middle Province" of the United States.* It possesses marked features
whereby it is distinguished from the western littoral Province, or Pacific
region proper, as well as from the Eastern Province. Most of the character-
istics of the Arizonian Avifauna are shared to a considerable degree by that
of New Mexico; the main points of discrepancy being those few wherein the
valley of the upper Rio Grande differs from that of the Colorado. It does
not appear that the difference between the two slopes of the main chain of
the Rocky Mountains is in this region very strongly marked. In general
terms it may be affirmed that the Ornis inclines in character decidedly to-
wards that of the Pacific region proper, as might be expected from the posi-
tion of Arizona relative to the main chain of the mountains just named. But
still notable differences from the truly littoral Fauna are apparent ; and there
can be little doubt that the presence of so extensive a desert just west of the
Colorado exerts much influence in producing this result. At certain points
however in this desert, some species, respectively typical each of its own
habitat, are known to meet.f The features, dependent upon latitude, which
separate Arizona from adjacent regions, to the north or south, are by no
means so marked as those which distinguish it from the countries lying east
and west, and mainly consist in the introduction into the lower warmer parts
of the Territory, from Sonora, of several Mexican and subtropical species. A
"wedge," so to speak, of these types is pushed a little northward of Mexico,
and they are readily recognizable as a somewhat prominent element among
the birds of Southern Arizona, and of the Colorado valley for a considerable
distance. Perhaps this is more deciedly the case here than at other points
on our southern border. A considerable number of species properly belong-
ing to the United States Fauna, and generally distributed throughout Ari-
zona, retire in winter beyond the Sonoran border ; while at the same time it is
interesting to note that some speciesj breed quite high up in Arizona, or even
further north, which are at the same time summer residents of the table lands
of Mexico. To the northward, neither the climate nor physical geography of

Arizona are sufficiently diverse from those of adjacent Territories to produce
any special differences in their Avifaunae; unless indeed the apparent absence
of one family* can be substantiated as a marked peculiarity.

Some facts of physical geography have a marked influence upon the birds.
From the dearth of water throughout almost every portion of the Territory
tbere results, as a natural consequence, a great paucity of Grallatorial and
Natatorial forms ; so much so, that with a few prominent exceptions, a list of
the Water Birds of the Territory is little more than an enumeration of those
of the Colorado and Gila Rivers. There is also to be noted, as an interesting
fact, the effect of the hot, arid, desert wastes of the region of the Gila, and
Southern Arizona generally, upon the colors of the species found there. A
light, dull, apparently faded condition of plumage, in which some shade of
gray is a predominant tint, and all lines and streaks are more or less obsolete
in character, is met with in numerous instances, forming true local races or
varieties. In other casesj- the specific characters which distinguish birds of
this middle southern province from other closely allied species, partake in a
measure of this peculiarity.

Our knowledge of the Ornis of Arizona has been hitherto chiefly obtained
from the collections made by the naturalists attached to several of the United
states Government Surveys of various regions of the West. The expeditions
along the 35th and the 32d parallel passed through different portions of the
Territory; the Mexican Boundary Survey along its southern border; that of
the Colorado passed up the river to the head of navigation. The first men-
tioned of these, under Capt. A. W. Whipple, with Dr. C. B R. Kennedy and Mr.
H. B. Mollhausen as naturalists, passed very near the present site of Fort
Whipple; and its collections agree most closely with my own. Collections
of some private individuals have added materially to the results of these Ex-
plorations ; especially those of Dr. J. G. Cooper, who spent several months at
Fort Mojave, on the Colorado River, in latitude 35° N. To the observations and
collections of this gentleman I shall have frequent occasion to allude ; and I
am indebted to him for free access to his MSS. notes, which are of special in-
terest and value, not only as adding some species to my list, but as affording
an opportunity of comparing the birds of Fort Whipple with those of a point
in the Colorado valley, at nearly the same latitude ; whereby the effect of the
differences in physical geography is finely elucidated. My own observations,
made during the sixteen months I resided in Arizona, extend over the Ter-
ritory from east to west, chiefly near the line of the 35th parallel; and along
the valley of the Colorado from Fort Mojave to Fort Yuma. It was chiefly
at Fort Whipple, and the mountainous region of that vicinity, that my collec-
tions were made. This particular locality possesses a rich and varied Avi-
fauna; numerous features of which are quite peculiar, as might be expected
from the following facts regarding its situation and relations.

Fort Whipple is very nearly in latitude 34° 30/ N.. longitude 112° W. (from
Greenwich.) It is difficult to give an estimate of the altitude of the vicinity
with anything more than approximate accuracy, in consequence of the broken
and varied nature of the surface. It may be stated, in round numbers, as be-
tween 4000 and 5000 feet ; but in several directions, and more particularly
to the southward, there are confused masses of short mountain ranges or ab-
rupt isolated peaks, which rise far above the level indicated by the preceding
figures. The altitude of the San Francisco mountains, about sixty miles a
little east of north of Whipple, has been fixed at about 12,000 feet. The main
point of interest which attaches to this particular locality — Fort Whipple —

* The Telraoiiidie. I have never seen nor heard of a finale species of grouse in Arizona. But
the northern portions of the Territory are so imperfectly explored that it is not safe to assert their
entire absence. Dr. J. G. Cooper has seen the Centrocercus urophasianus ou the Mojave Kiver;
the southernmost point, 1 believe, from which it has thus far been recorded.

t Of which Ilarparhynchus Ltcontzior criisaiis, as distinguished from H. redivivus of the Pacific
coast, is a go.id example.

is that it is nearly upon the dividing line between two tracts of country quite
diverse from each other in those points which chiefly affect the distribution
and migration of species. A single day's journey to the southward gives us
changes in the birds, so great, that I do not hesitate in comparing the differ-
ence to that which exists between the Middle Atlantic and the Gulf States, in
the eastern Province. Very numerous species,* not detected at any season at
Fort Whipple, are yet found abundantly within fifty miles to the south and
southwest. At the same time the locality is a true component of the eleva-
ted and cold regions to the northward, and assimilates in this respect to Utah
and Nevada. Intermediate in situation between the two great valleys of
southwestern United States — those of the Rio Grande and Colorado Rivers, — it
draws tribute in a measure upon each of them, though, as might be supposed,
vastly more from the latter than the former. In this connection I may advert
to an interesting point, which I consider as quite probable, though contrary
to the usual laws of migration ; viz., that many of the birds of the Colorado
vallej, which are there winter residents, instead of migrating far to the north
in spring, by turning simply to the eastward, find in the region of which
Fort Whipple is the southern limit the conditions necessary for breeding
grounds. That such is a fact would seem to be indicated by comparing the
forms common to both Mojave and Whipple; the summer residents or spring
migrants of the latter place being usually winter residen's at the former
locality ; but can only be incontrovertible* proven by showing that some
species wintering at Mojave are not found directly north of that point in
summer ; and that they do breed in the Whipple mountains.

The seasons are well pronounced at Fort Whipple, and do not differ nota-
bly from those of the Middle Atlantic States. This enables us trenchantly to
divide those of its birds which are not permanent residents, into summer and
winter residents, and migratory species passing through in the spring and
autumn. And I have noticed in many instances that the times of arrival and
departure of non-residents are strikingly similar to those of the migratory
species passing through Washington, D. C. Quite the reverse is the case in
southern Arizona ; where the protracted heat and drought of a long summer,
which encroaches on intermediate seasons, disturbs the regularity of migra-
tion ; or even entirely takes away from some species the migratory impulse.

The immediate vicinity of Fort Whipple is admirably adapted to ornitho-
logical pursuits in the very varied character of surface presented within the
compass of a day's walk. Pines constitute the main feature of the Sylva,
covering all the mountains down to what may be considered as the average
altitude of the locality. .An extensive undulating plain stretches to the north-
ward, partially grassy, partially covered with the characteristic shrubs of
the country. Ranges of broken low hills, sparsely covered chiefly with sev-
eral species of dwarf oak, or so nearly naked as to be little more than huge
masses of metamorphic rocks, attract their share of species. The head of
one of the forks of the San Francisco River flows past; at times a considera-
ble stream, but usually dry. The vegetation along this, as well as all other
water courses of the Territory, has as its most prominent element the ever
present Populus moniliferus ; together with species of Salix, Primus, Castanea,
etc., the bases of which trees are as usual tightly sewn together by a tangled
matted network of rank undergrowth ; the whole forming a tract peculiarly
yielding, as every ornithologist knows, of variety and value in specimens. A
small rather open swamp near by affords several species, which, but for its
presence, would not form a part of the birds of the locality.

By adding to the species observed at Fort Whipple, and characteristic of
that locality, such others as have been ascertained to inhabit any portion of
the Territory, the subjoined list becomes an exposition of the present state of

our knowledge of tbe Arizonian Ornis. I have included no species in the
list which has not actually been detected in the Territory, or which must
necessarily be found there, from the known range of its habitat ; but frequent
reference is made to species, not yet recognized as components of the Arizo-
nian Avifauna, which in all probability are hereafter to be detected. In view
of the favorable circumstances attending the preparation of the list, I do not
think that very many species remain to be added to it. Still, as my opera-
tions were conducted at the most imminent personal hazard from the con-
tinued presence of hostile Indians, — the wily and vindictive Apaches — which
always cramped, and at times necessitated entire cessation of investigations,
it maybe perhaps that some species have been overlooked ; and I have only
the same excuse to offer, for some other shortcomings, of which no one can
be more fully aware than myself. I have taken care to eliminate the Whip-
ple birds, as contradistinguished from all others of the Territory, in order
that attention may be drawn to their peculiarities ; considering the Fauna of
any natural geographical region as more interesting and instructive than that
comprised within arbitrary political boundaries, since the latter almost al-
ways include fragments of two or more diverse Faunas ; of which fact the
very region now under discussion affords an example. The Whipple species
are preceded by an uninclosed number ; all others have their number in pa-
renthesis. It has been my aim merely to add to the remarks elucidative of
the distribution of the species, such purely technical observations, compari-
sons of closely allied forms, descriptions of immature or little known states
of plumage, as seemed quite pertinent to the subject. In a few cases syno-
nymy is introduced for reasons which will be obvious. Except in a few in-
stances of special interest I have nottouched upon the natural history proper of
the species, reserving for future elaboration the mass of ornithobiographical
notes which I have taken care to accumulate. All remarks are to be under-
stood as referring to the species as observed at Fort Whipple, and by myself,
except when the contrary is explicitly stated.

VULTURID.E.

1. Cathartes aura (L.) Illig. ^

Summer resident ; abundant. Arrives last week in March ; remains until
latter part of October. Resident in the southern portions of the Territory.

(2.) Cathartes Californianus (Shaw,) Cuv.

Resident in Southern Arizona. Individuals observed at Fort Yuma, in
September, 1865.

FALCONWsE.

3. Falco (Tinnunculus) sparverics L.

Resident ; very abundant. In highly-plumaged spring birds, the cere, the
feet and the edges of the eyelids are bright vermilion, not yellow: the claws
and bill bluish black.

4. Falco (Hypotriorchis) columbarius L.

Common ; resident. " A specimen taken by me at Fort Mojave is remark-
able for its light colors " (Cooper). A light, dull, faded condition of plumage
has been already adverted to as characterizing, in many instances, birds from
the Gila and Colorado Valleys.

In the immense series of " Pigeon "-Hawks which I have examined from
all parts of the West, I find a few specimens which constantly differ, to a
marked degree, from any and all of the exceedingly diverse plumages under
which the typical F. columbarius presents itself. These specimens are inva-
riably much larger than any others in the series ; are much lighter colored,
(yet not dull or faded,) and differ constantly in the increased number of
light and dark bars on the tail. Compared with a European specimen of

[March,

NATURAL SCIENCES OF PHILADELPHIA. 43

Falco xialon, they agree in every particular. I think it most probable that
future careful research will demonstrate satisfactorily the existence of a
species hitherto usually confounded with some of the protean plumages of
F. columbarius; but quite distinct from the latter, and doubtless referrible to
the European type above mentioned. In fact, a Falco sesalon has been quoted
by Townsend and Nuttall as from the northwestern portions of the United
States ; though not usually recognized by later ornithologists.

(5.) Falco (Hypotriorchis) femoralis Temm.

South Arizona, near the Sonoran border. Specimens were obtained by
Lieut. J. G. Parke's Expedition along the 32d parallel ; and by the Mexican
Boundary Survey.

It is quite possible that the F. aurantius Gm. extends northward through
Sonora into the southern portion of Arizona.

(7.)Accipiter Cooperi Bon.

This generally distributed species is found throughout the Territory.

8. Accipiter Mexicands Swains.

Common, resident. Iris, cere, legs, and feet light yellow. Bill bluish
black. Claws black.

I have seen young birds of this species, reared by hand from the nest, so
thoroughly domesticated as to come to their master on being whistled for,
and perch upon his shoulder, or follow him when shooting small birds for
their food. They were allowed entire liberty. Their ordinary note was a
shrill and harsh scream ; a low, plaintive, lisping whistle was indicative of
hunger. •

The shape of the tail of this speeies is decidedly less rounded than that
of Cooperi, and is a feature of considerable value in distinguishing the
female Mexicanus from the male Cooperi.

Resident. Abundant throughout the Territory.

Variations of Plumage of Buteo borealis, etc., in Pr. Bost. Soc. Nat.

Hist, for 1861 : considers montanus Nutt., calurus Cass., and probably

also Cooperi Cass., as referrible to borealis.

*I think it very likely that polyagrus is not the first distinctive name this Hawk has received.
The description of Falco mexicanus by Schlegel, as above cited, is substantially as follows: —
•'Wing 11.50 to 13; tail 6.50 to 7 50; legs finely scaled, feet yellow; above brown, paler on the
tail; head and nape edged with rusty brown; quills with rust-colored spots; stripe through the
eye, spot on nape, and middle of auriculars whitish; beneath white, each feather with a Darrow
blackish drop-shaped spot; large lateral feathers covering flanks brown, with some rust-colored
transverse spots. The young bird has the edges of the feathers above light, the spots below
larger, and the feet greenish yellow." A fuller description is in the first number of Dr. Schlegel's
Catalogue of the Pays-Bas Museum, above cited. These descriptions are pertinent to F. polyagrus
in most respects; but, in view of some discrepancies, {color of the legs, which, in polyagrus, are
light dull blue, etc.,) I do not wish, at present, at least, to make the change of names, though
such a procedure may hereafter he considered necessary. Mr. Cassin himself refers (B. N. A.,
1868, p. 12,) to this name of Dr. Schlegel's, as very probably the first designation of the species.

Falco buleo, Audubon, Orn. Biog. ; Sw. & Rich. F. B. A., according to
Cassin.

The most abundant and characteristic species of the larger Hawks; resi-
dent, but particularly abundant during the winter months. It may be
readily recognized at any distance, when flying, by the very dark-colored
area presented by the lesser under wing coverts, sharply contrasted against
the very light colors of the rest of the under surface of the wings. The iris
is clear light brown ; the bill bluish black ; the cere, legs and feet light
yellow.

In the Proceedings of the Boston Society of Natural History for 1861,
appeared a paper by Dr. Henry Bryant, on the variations of the plumage of
Western North American Buleones ; in which facts are elicited tending to
demonstrate that nearly all the species enumerated as valid by Mr. Cassin, in
1858, may be reduced to two. One of these, of which borealis Gm may be
taken as the type or parent stock, and for which the name must stand, is
large and muscular, with a strong bill, long stout tarsi, and a rounded
wing. Here Dr. Bryant would range montanus Nutt., calurus Cass., and pro-
bably also Cooperi Cass. ; together with a specimen in the Philadelphia
Museum, which has been labelled and usually called Ifarlani. The other
species is distinguished by its smaller size, more slender form, longer and
weaker tarsi, and more pointed wing. Harlani* Aud. is considered as the
first name of this species ; and to it are referred Swainsonii,f Bairdii of Hoy %
and of Cassin; insignatm,?^ Cassin, and oxypterus || Cassin. Dr. Bryant gives
careful measurements of these supposed species, having access to the types
of many of them, and fiuds that, if we are to take size and proportions
alone as indicative of specific validity, we can admit but the two species he
characterizes ; while, if we are to be guided by color, we cannot avoid still
further increasing the number of species to be recognized to such an extent,
that (together with the other undoubted species, such as linea/as, pennsyl-
vanicus, etc.,) we should have a total of twenty- three inhabiting North
America.

It cannot be denied that our constantly increasing knowledge of the dis-
tribution of North American Buteones, and of the "theory of variation"
which is applicable to them, decidedly tends towards a confirmation of Dr.
Bryant's views. Nevertheless, I am by no means prepared to accept with-
out reservation the extreme conclusions arrived at. I prefer, at present, to
enumerate the species — or varieties, if they are only such — as determined by
Mr. Cassin ; considering the names given as at least indicative of strongly
marked, and apparently geographical, though perhaps not permanent,
varieties.

My specimens have a large pectoral area dark chestnut brown, not very
different in color from the superior aspect of the tail. I have seen other
specimens from Fort Tejon, Cala., in which the breast is still brighter
chestnut, in marked contrast to the fuliginous brownish black of the rest of
the plumage. Utah, New Mexico, Arizona and California seem to constitute
the special range of this species or variety.

B. " Cooperi" has only been taken from Southern California, (Santa Clara
County, Cooper,) and, as but a single specimen is known, it is impossible to
decide with certainty upon its relations to borealis.

(12.) Buteo "Harlani Audubon."

Individuals identified with this supposed species of Audubon by Mr. Cassin
and Mr. Lawrence are from New Mexico and California ; so that the bird
necessarily ranges over the intermediate ground of Arizona.

Dr. Bryant considers that the specimens thus identified present nothing
incompatible with their being regarded as a variety of borealis. And it is
quite probable that the specimen upon which Audubon himself based the
name " Harlani1' is really referrible to a state of plumage of borealis. This
must be finally determined by examination of the type in the British Museum.
But the name " Harlani Aud." is employed by Dr. Bryant in his paper to
designate a species radically distinct from borealis in all its variety, and is
the one to which the three following names are by him referred.

a variety of borealis.)
A species or variety of extensive distribution throughout the West.
Colorado Chiquito River, Ariz., Dr. G. B. R. Kennerly. I never met with it at
Fort Whipple, though, beyond a doubt, it is to be found there.

Some of the states of plumage of this bird are so exceedingly similar to
those of B. vulgaris of Europe, that it has been thus malidentified by certain
American writers. See Cassin, B. N. A., pp. 19, 20, 21, for elucidation of
changes of plumage, geographical distribution, and synonymy.

after detected. (Fort Fillmore, N. M., Dr. T. C. Henry.)

knowledge, been taken as far south as Arizona, though detected at various
other points in the West.

taken on the Colorado Chiquito by Dr. Kennerly. I am informed by Dr.
Cooper that it is an abundant bird in Southern California. It will doubtless
be hereafter found at Whipple.

This fine species is radically different from any of the foregoing Buteones,
belonging to a group subgenerically distinct, partially characterized by a
different amount of feathering of the tarsi. Among North American species
it is only intimately related to lineatus, from which species the study of its
neossology readily enables us to distinguish it.

B. zonocercus, Sclater, Trans. Zool. Soc. Lond. 1858, p. 263.

A single specimen, procured on the Gila River, Sept. 24, 1864. The species
is doubtless restricted in its northern range to the warm valleys of the Gila
and Lower Colorado.

This interesting Mexican species was first found within the limits of the
United States by the indefatigable Cooper, who procured a specimen in Santa
Clara County, California. Without being aware of this at the time, I redis-
covered it myself in Arizona ; an additional example of what has occurred in
several instances in our operations in the West, during the greater part of
which each was ignorant of the other's exact whereabouts and labors. I
must yield to my friend the priority of discovery, although I have the pleas-
ure of first presenting the species in an American publication as an addition
to the United States Fauna.

This large, noble, and by far the handsomest of our Falconines, hitherto
only known from California, is found quite abundantly about Fort Whipple,
especially in winter. It is probably a permanent resident there. It chiefly fre-
quented meadows, plains and more open woods. 1 observed it to be quite numer-
ous on the dry, level, grassy plains of Southern California. I usually found the
stomach filled with Geomys, Arvicola, or Hesperomys. In life it may always be
readily recognized by its conspicuously white under parts, contrasted with its
dark chestnut tibiae and reddish back.

No. 1114, taken Dec. 2, 1864. Male. Length 22-50; extent 54-50; wing
16-25; tail 9-50 ; tibia 4-80; tarsus 3-25; middle toe 125; its claw -75; outer
toe -85; its claw -55 ; hallux 1-00; its claw 1-00; bill along culmen 1-50;
along gape 2-00; its depth at base -90. No. 1115, taken Dec. 6, 1864. Fe-
male. Length 23-25 ; extent 56-50 ; wing from carpus 46-75 ; tail 10-00 ;
tarsus 3-40 ; the other measurements not differing notably from those of the
male above given.

When perfectly adult, the whole under parts, from chin to under tail cov-
erts, inclusive, are pure white. In the majority of specimens, however, there
will be found a few slender, sharp, shaft lines of black on the chin; which,
as they pass down the breast, become broader, and tinged with chestnut.
Usually, also, the feathers of the flanks have small, isolated, interrupted and
incomplete bars of chestnutand black. Less mature specimens exhibit a con-
tinuation of these bars quite across the lower part of the abdomen, and they
are so broadened as to form somewhat hastate spots. Some of the feathers
of the flanks are tipped with chestnut. The chief other variations in adult
birds seem to be a greater or less intensity of the deep color of the tibiae, a
lighter or darker shade of ferrugineous on the back, and a fainter or more de-
cided wash of pearl grey on the superior surface of the tail.

The bill is dark leaden bluish black. The mouth is light purplish flesh
color, becoming livid bluish on the corneous portions. The cere, edges of
the commissure, tarsi and toes are bright chrome yellow. The claws are
black. The naked skin just over the eye is greenish, tinged with crimson
posteriorly. The iris of adult birds is fine light yellow ; of young ones
brown, more or less ochraceous with increasing age.

The following brief anatomical notes maybe of interest, as the species has
not hitherto been dissected. They relate chiefly to the alimentary canal :

Anatomical Notes. On the roof of the mouth a narrow but prominent me-
dian ridge runs from the very apex of the upper mandible to the fissure of
the posterior nares, widening, becoming less sharply defined, and more ob-
tusely papillated towards its posterior extremity. At a point about a third of
its length from its termination it is crossed at right angles by a very short,
transverse ridge, which connects it on either side with a lateral ridge. These
lateral ridges run parallel with each other as far back as the Eustachian ori-
fice, and are papillated for their whole length, which papilla? are anteriorly
sparsely distributed, short, stout and obtuse ; posteriorly gradually becoming
thick-set, long, soft and acute. The ridges themselves terminate abruptly in
the smooth, soft, mucous membrane of the posterior portions of the palate,
measuring 1-60 inches in length. That portion of the palate between these
ridges and the nasal fissure is roughened by numerous short, blunt tubercles.
From the extremity of that portion of the nasal fissure which has soft, ele-
vated, approximate ridges, there runs outwards on either side a fringe of
delicate papilla;. Rather more than the posterior third of the nasal fissure
stands broadly open, and has hard, immobile, bony edges, over which the
mucous membrane is tightly and smoothly stretched. The nasal aperture
measures in total length 1-25. Just posterior to it, on the median line of the
palate, is the opening of the Eustachian tube, situated in the centre of a smooth,
somewhat vaulted space. In shape it is oval, and its edges, though somewhat
mobile, are not completely approximable. From its posterior extremity, on
either side, a fringe of soft papilla? curves obliquely outwards and forwards.
The rest of the palate is not noticeable. Posteriorly it is very soft, and nu-
merous vessels may be seen ramifying beneath its mucous membrane. An-
teriorly it becomes harder and more fibrous, and finally, towards the tip of
the bill, quite corneous.

The tongue is large and fleshy, its tip obtusely rounded, its lateral outline
convex, its dorsum with a median furrow, its under surface with a corres-
ponding ridge, its posterior extremity deeply bifid, the edges of the fork
corneous, and armed with stiff, hard, papillae. The outermost of these pa-
pillae is greatly developed, forming a large, strong, acutely pointed spine.
The tongue is -75 long ; its laryngeal fissure '50. The elevated space
just posterior to the rima glottidis is pure white, and thickly beset with
stiff, acute papillae, some of which have black tips.

On the floor of the mouth, on either side of the frenum linguae, at the apex
of the angle formed by the divergence of the inferior maxillary rami, lies a
thin, flattened, broadly oval gland, a third of an inch long, of a deep pur-
plish red color. Its surface is studded with numerous depressed puucta,',the
orifices of the emunctory ducts.

The trachea is 5-50 inches long, and -45 wide at its superior extremity ;
rings about 90 in number. It is broad and much flattened superiorly, but
towards the lower larynx becomes more cylindrical. The lateral muscles are
well developed. The lower larynx, as usual in this order, is quite simple.
The bronchial half-rings are 15 in number, all small, soft and weak.

The oesophagus is extremely capacious and dilatable. The distended crop
is irregularly ovoid in shape ; 3-50 long by about 2-25 wide.

The proventricular glands form a complete zone, with a uniform width of
1-25. The proventricular parietes is about one-twelfth of an inch in
thickness. The individual glands are large enough to be readily discernible
to the naked eye ; closely aggregated in the parenchyma of the parietes. Their
orifices are plainly visible, thickly studding the whole internal surface of the
organ ; and during active digestion the mucous membrane is covered with
their thick, glairy, viscid secretion.

The fully distended gigerium occupies about three-fourths of the abdominal
cavity. It reaches within an inch of the rectum, inclining towards the left

side of the abdomen, with the internal parietes of which it is in close ap-
proximation. The intestines all seem crowded backwards, downwards and to
the right. There is no apparent constriction between the proventriculus and
gigeriuin ; but from the termination of the oesophagus proper the calibre of
the canal regularly increases, so that the two stomachs together form a pyri-
form mass, its large end directed backward. The walls of the gigerium are
thin ; the mucous membrane quite smooth. The pylorus is nearly circular in
shape ; i's aperture quite open and direct. It is guarded by elevated folds
of mucous membrane, forming partial valves. The opening is situated about
the middle of the right side of the gizzard.

The duodenal fold is between three and four inches in length. It curves
around the right side and fundus of the gizzard, separating the latter from
the rectum, and thence returns upon itself to its point of departure.

The intestine then curves around the dorsal aspect of the gizzard until near
the median line of the body, whence it descends nearly in a straight line, in
the right iliac fossa, almost as far as the rectum. After numerous short con-
volutions in this region, it again ascends, on the right of the spine, till it re-
gains the dorsal aspect of the gizzard near the origin of the duodenal fold.
It then traverses the gizzard from right to left, and descends in the left iliac
fossa, half way to the rectum, when abruptly returning on itself along the
left side of the spine, it forms a loop about an inch long. Here, after again
abruptly reversing its direction so as to point directly backwards, it termi-
nates, at the coeca, in the colon.

There are two cceca, each about one-eighth of an inch long, very small,
perfectly straight, obtusely rounded at their extremities, and closely adherent
by cellular tissue to the walls of the colon.

The colon is very short, being less than two inches in length. It is a per-
fectly straight tube, running directly backwards along the median line of the
sacrum. Its diameter does not exceed the average of the "small" intestines,
and is less, in fact, than that of the duodenum. Between the ischia it ex-
pands into a large, nearly globular, though somewat pyriform rectum, about
an inch in length. A spincter partially guards the recto-colal passage.

The pancreas in the specimens examined was not, as usual, slender and
elongated, and received in the fold of the duodenum ; but was short, thick
and obtuse, and closely applied to the right side of the gizzard.

The spleen measures a third of an inch in length, and is of a flattened,
ovoid shape, and dull reddish purple color. It rests on the dorsum of the
gizzard, a little to the right, and high up near the proventriculus.

The liver is large, and its two lobes are of about equal size. They lie one
on each side of the abdomen, their commissure being directly on the median
line of the body. Their superior concave surfaces combined are in apposi-
tion with the gizzard and intestines ; their convex inferior surfaces are accu-
rately moulded to the thoracic parietes. Anteriorly they diverge to receive
the apex of the heart between them ; posteriorly they are in close mutual
apposition.

The total length of the alimentary canal from pylorus to anus is about 40
inches.

the continent. I have met with it as high up as Fort Leavenworth, on the
Missouri River.

[Note. — The following extract from my Journal may be of interest : " Camp
on San Francisco River, near mountains of same name, July 13, 1865. A
pair of exceedingly large rapacious birds sailed over camp this evening. Their
Slight was easy, graceful, firm, and sustained for a long time with no visible
motion of the wings, which latter were exceedingly long, pointed and acutely
angulated at the carpal joint. In size they about equalled Bald Eagles ; but
the shape of the wings and mode of flight were very different and intimately
resembled those of the Turkey Vultures. The entire under parts of these
birds were pure white; their upper parts were not visible." I could not pro-
cure a specimen, nor can I now refer the birds to any species known to me,
unless, possibly, they were the Sarcorarnphus papa ; a species which may be
included hereafter in our Fauna, though its presence within our limits has not
yet been positively substantiated.]

In addition to the preceding Strigides a species of Athene occurs in Arizona :
but whether h ypogea or cnnicularia I cannot now determine positively. The
Syrnium occidentale Xantus, (Pr. A. N. S., Ph. 1S59, type from Fort Te.jon)

Nyctale albifrons on the Sierra Nevada of California, which causes Arizona to

My numerous specimens present no material discrepancies from Wagler's
original description in the Isis. I think it far best, with our present informa-
tion on the subject, to refer the Oregonian, Californian and Arizonian bird to
this species of Wagler, as Mr. Cassin has done. Should the Mexican bird
ever be found to differ from the North American, the latter is to be called G.
californicum after Sclater, as above quoted.

My citations of Audubon's and Cassin's works, (ut supra) all refer to the
North American bird, though these authors erred in applying to it either of
the names infuscatum or passerinoides, both of which refer to South American
species, in all probability identical with each other, and quite distinct from
our bird. Mr. Cassin himself corrects his error in the " Birds of North
America; " and with this gentleman's later views of the synonymy I entirely
agree.

The sexes of this little Owl differ much in size. A male before me measures
only 5 "50 X 14*50, but the tail feathers are quite imperfect ; had they grown
out fully the bird's lens;th would have been about 7.00. The female is larger,
measuring 7*50 X 15-25. The male is rather darker colored than the female :
t lie spots above more numerous and smaller; the imperfect nuchal collar of
black and white much better defined than in the other sex, where it is almost
obsolete. In both sexes ihe iris is bright yellow ; the mouth light purplish
flesh ; the bill, cere and feet light greenish yellow ; the soles chrome yellow ;
the claws black.

A diurnal and crepuscular rather than a nocturnal species. The stomachs
of those individuals examined, contained the remains of orthopterous and

abundant.

MICRATHENE Coues, nov. gen.

Generic Characters. — Bill small and weak, compressed at the base, where it
is densely covered with recurved feathers terminating in stiff bristles ; out-
line of culmen and gonys moderately convex ; lower mandible obsoletely
notched. Facial disk not conspicuously defined, imperfect behind the eye.
Wings exceedingly long ; measuring from the carpal joint rather more than
two-thirds the total length of the body ; much rounded, the exposed portion
of the first primary only two-thirds that of the longest one ; third and fourth
longest, fifth but little shorter, second about equal to the sixth. Tail of mod-
erate length, not graduated : rectrices broad to their very tips. Tarsi of mod-
erate length, feathered only for a short distance below the tibio-tarsal joint ;
the rest of their extent, and the superior surface of the toes, clothed with
bristly hairs. Claws unusually small and weak, moderately curved ; the
outer one reaching a little beyond the base of the middle one ; the inner in-
termediate between outer and middle ones. Middle toe and claw about as
long as the tarsus. Hallux elongated. Of small size, being among the most
diminutive of known Owls.

Type. A'hene Whitneyi, Cooper. *

With the size and general aspect of Glaucidinm, this genus differs greatly
from it as follows: The bill is smaller, weaker, less strongly hooked and den-
tulated. The wings are much longer, and the tail much shorter. The tarsus
is unfeathered except for a short space superiorly. The claws are so small,
and weak as to be hardly more than insessorial rather than raptorial in char-
acter. The proportions of the tarsus and toes differ decidedly. Nor has it
much in common with Athene, except the partially denuded tarsi ; the rela-
tive prop irtions of the tarsus and toes to each other being quite different in,
the two genera ; Athene having the middle toe and claw about two-thirds the-
tarsus, instead of fully as long. The claws of Athene are very long, acute andi
little curved. While both genera are very long winged, there is a decided
difference in the shape of the wing; that of Athene being much the most
pointed, in consequence of the greater elongation of the first and second pri-
maries. I think it more than probable that Micrathene is a truly arboreal,
genus, like GUiacidtKin, thus differing radically in its habits from the species -
of Athene.

In conversation with me Dr. Cooper intimated his belief that the bird was.
not a true Athene ; and my critical examination of his type, made at his own.
request, amply confirms the accuracy of his opinion.

PICID^E.

38. Picus Harrisii Audubon.

One of tlie most common and characteristic birds in the vicinity of Fort
Whipple.

The iris is brown at all ages ; but varies from a clear light reddish brown to
a dark blackish brown. The bill and feet are horn-bluish black. The speci-
mens from the same locality hardly vary notably in size, though the male is
usually larger than the female. None of my specimens approach in size the
immense race found in Arctic America.

No specimens out of a very large series, exhibit the slightest tendency
towards the smoky brown tinge, or discoloration of the under parts, seen
almost constantly in birds from California and Oregon and Washington Ter-
ritories ; but have the under parts pure white, and usually, too, with no in-
dications of the obsolete lateral and crissal black streaks seen in the race from
the Pacific coast. Specimens not in high plumage frequently have the pri-
maries and rectrices gray instead of black ; and this gray is sometimes so
faded towards the apices of the feathers, as to be almost white.

It is a little singular that in a locality where P. Harrisii is resident, and so
very common, P. Gairdneri should be either not found at all, or so very
rare that I <li I not identify it with certainty during my whole stay ; though I
am under the impression that I once saw a single specimen.

Fort Whipple appears to be about tb.3 northern limit of this species. It is
not very common there, being only a summer visitant, breeding sparingly ;
further south, through the Territory and in the Colorado Valley, it is abund-
ant. It does not appear to cross the Colorado Desert into California, (whure
the P. Nuttalli replaces it,) but extends far southward into Central America.
A male shot June 5th has the feathers worn off the belly, as if incubating.
Young birds just fledged were taken July 10th. The nest was in the top of a
live-oak tree. The heads of the young at this season have rather more red
on them than those of the adults.

Iris deep reddish brown ; bill dark slaty black ; legs and feet horn bluish.
The average length is 6*50 inches ; some specimens measure nearly 7 inches.
P. Nuttalli seems to be exclusively a toast species, not crossing to the Colo-
rado Valley-

SPHYRAPICUS Baird, 1858.

The genus Splii/rapicus instituted by Prof. Baird, in 1S58, to replace the
preoccupied and therefore untenable Pilumnus of Bonaparte, (type P. t/n/roi-
deus Cass.) is a most natural one, widely separated from other genera by sin-
gular anatomical peculiarities as well as striking external features. Its North
American components are all very closely allied, notwithstanding that Prof.
Baird intimates his doubts as to the propriety of referring P. Williamsani
here, and Prof. Reichenbach has been inclined to consider P. thyroideus as a
Cnlajit s. I am familiar with the habits and anatomical peculiarities of all
our North American Sphyrapiei except 5. ruber, and my study has revealed
points so essentially at variance with other Picida-, that I am inclined to in-
stitute for the reception of the genus a subfamily ■Spliyrapicince.

[March,

NATURAL SCIENCES OF PHILADELPHIA. 53

The genus in question is a xylophagous rather than an insectivorous one.
I do not mean that the Sphyrapici never eat insects, for coleoptera and their
larvae may often be found in their stomachs. But their main sustenauce is the
cambrium, or soft, inner, live bark of trees, the succulent juices of which
they appropriate to their ceconomy, rejecting the ligneous, uunutrious fibres
in the ordinary method. They are, in fact, true "Sap-suckers," and it is
their devastations upon fruit and ornamental trees which have brought the
family of woodpeckers into such disrepute among agriculturalists ; a class
not ordinarily observant enough to discriminate between these birds and the
harmless or rather beneficial species of Picus Melanerpes, Centurus, etc In-
stead of simply "tapping" trees, — generally their decayed or dead portions
too, — to extract the injurious beetles and their larvae lurking within, the Sphy-
rapicines denude live branches of their bark, often for an area of several
square inches at a time. I have before me specimens of wood thus a tacked,
from which the bark has been removed from large irregularly shaped spaces ;
and the result, as might be expected, is exceedingly different from that pro-
duced from the simple drilling of little holes by the insectivorous genera. Be-
sides the cambrium, all the species, particularly in the fall, feed extensively
upon ripe fruits and berries of all sorts.

The anatomical peculiarities which produce this remarkable difference in
habits are very striking, and involve to a greater or less extent the whole lin-
gual, salivary and gastric apparatus. In the tongue itself, however, and its
bones, the most remarkable differences are to be seen. The tongue cannot be
protruded, as a dart, far beyond the tip of the bill ; the amount of extension
it is capable of not exceeding a fourth or a third of an inch. This is caused
by the great abbreviation of the apo-hyal and cerato-hyal elements of the hyoid
bone, which do not reach backwards much beyond the tympano-maxillary
articulation, instead, as in Picus, Colaptes, etc, of being produced so far as to
extend over the occiput to the top of the cranium, or even to curve around the
orbit of the eye in an osseous groove formed for their reception. The basi-
hyals which support the tongue are also shorter and somewhat differently
shaped. The tongue itself is short and flattened, with a superior longitudi-
nal median groove, and a corresponding inferior ridge. Its tip is broad and
flattened, and obtusely rounded, and provided with numerous long and soft
bristly hairs. All these features are quite diverse from the long, protruda-
ble, subulate, acutely pointed tongue of Picus, etc., armed near its tip with a
few strong, sharp, short, recurved barbs.

The muscular apparatus for the movements of the tongue differs, of course,
in a degree corresponding to these modifications of the hyoid bone. I am in-
clined to believe, though I have not prosecuted my dissections far enough to
speak positively, that there exist differences in the salivary glands, and,
perhaps, in the gastric mucous membrane, rendered necessary by the radical
diversity of the ingesta.

My attention was first called to these interesting points by a communication
from Dr. P. R. Hoy, of Wisconsin, in one of the newspaper periodicals of
that State ; which I believe was the first published notice of these facts, and
that gentleman's observations I have amply confirmed by my own scalpel and
field studies.

It is unnecessary to detail the external characters of this genus, as they
have already been given in ample detail by Prof. Baird.

red, and invading to a considerable distance the pectoral spot of pure, deep,
glossy, greenish black. In the adult female the chin is white, bordered pos-
teriorly by a somewhat semilunar patch of red, not so intense in tint as that
of the male, nor so broad. The pectoral black spot, though rather smaller,
is equally pure in color. Both sexes invariably have the red crescentic nuchal
collar, separated from the red pileum by a distinct line of black. Autumnal
birds have the white portions of the upper parts and the belly more or less
strongly tinged with lemon yellow, especially noticeable on the abdomen.
Birds of the year hardly differ from the adults, except that the pectoral spot
is only indicated by a few isolated black feathers scattered through a dull grey
area. Tlie nuchal collar is always observable, though its continuity may not
he perfect. Independently of age, sex or season, there are great variations in
the. size and shape of the bill to be observed in large series from different lo-
calities.

This is to be considered as a thoroughly established species. In an im-
mense series of skins of both species before me from all parts of North
America, there is not one which cannot unhesitatingly be referred to one or
the other species.

41. Sphyrapicus Williamsoni (Newb.) Baird.

Picus Williamsoni, Newberry, 1857, (Oregon.) Melanerpes rubrigularis,
Sclater, 1858, (California.) Sphyrapicus Williamsoni, Baird, 1858.

Resident. Not uncommon. Exclusively pinicoline in the regions where I
have observed it. Ranges from both slopes of the Rocky Mountains to the
Pacific, fiom as far north at least as Oregon. Fort Whipple is probably near
its southern limit.

(No. 844, Oct. 13, 18b'4. rj\) Length 9-5; extent 16-75. Iris dark brown.
Mouth pinkish flesh color. Bill bluish black. Feet dull greenish black.
Claws black.

This species exhibits the anatomical peculiarities noticed under head of the
genus Sphyrapicus, and its habits aie entirely correspondent.

42. Spbyrapjcts thyroideus (Cass.) Baird.
Resident. Very rate. Cliierly pinicoline.

The range of this species is now known to include both slopes of the Rocky
Mountains, from Oregon to the Rio Grande, and probably it extends through
Arizona to the Sonoian border.

Some male specin ens have the grey chin more or less suffused with reddish,
forming a mental spot something like that of Williamsoni. Neither sex ap-
pears to have any red about the crown or nape, a very unusual fact if such
he invariably the case.

This species is strictly congeneric with Sphyrapicus varivs in anatomical pe-
culiarities and in habits, and has nothing in common with Colaptes beyond
some similarity in the pattern of coloration.

Sphyrapicus ruber, as a bird of the whole Pacific Slope of the Rocky Moun-
tains, will most probahly be hereafter detected. It seems chiefly, however, a
coast species. The Uylatomus pileatus is undoubtedly an inhabitant of Ari-
zona.

43. Centueus uropygialis Baird.

1 Rare, and perhaps accidental in the immediate vicinity of Fort Whipple.
A common bird of the Gila and Lower Colorado River valleys. " Abundant
at Fort Mojave," (Cou]>er.) A species remarkable for inhabiting the Giant
Cactuses, (Lepidocerws (jiganteus and/.. Thurberi, of Englemann,) whence
is derived its provincial name of " Suwarrow '' or "Saguaro." Its plumage
is often found stain' d with the juices of these plants. It feeds upon their
fruit, but catches insects as well The female is similar to the male, except
that she wants the quadrate patch of red on the crown. The absence of the

yellow nuchal crescent, and of the yellow at the base of the bill are some of
the features that distinguish hoth sexes from the C. Jiaviventris.

44. Melanekpes fokmicivorus (Sw.) Bp.

Exceedingly abundant, being the commonest Woodpecker, not even except-
ing P. Harrisii. Resident. Found in all situations.

The tongue of this Woodpecker is rather brushed at the tip, like that of a
Sphyrapicus, than barbed, as in Picas, etc. Si ill it is exceedingly protruda-
ble, the hyoid bone being well developed.

This species presents variations in the color of the iris rarely equalled. In
a great many individuals the iris is pure white, and so it is usually described.
But this is not the color in even a majority of instances, for this white is
tinged with various colors, — red, blue, yellow or brown. A greater or less
admixture of red gives every shade from a clear rose pink to the most deli-
cate creamy white, and these tints are usual in adult spring birds of both
sexes. Varying degrees of yellowish or ochraceous are by no means rare.
Young birds are rarely found with pure white irides, for the color is usually
obscnred by a greater or less amount of blue or grey, producing a bluish grey
or a " milk white " tint. Rarely an individual is found with dark brown
irides. The latter seems to be purely accidental ; the admixture of blue to
denote immaturity, and the reddish tinge to indicate high spring maturity, in
each case quite independently of sex.

The moult, which commences in July, continues for an unusually long pe-
riod,— until November, — at least in some instances.

Adult birds are very constant both in size and plumage, but, at the same
time there is an immense variation in the length and stoutness of the bill in
different individuals. The black of the breast, and the lemon yellow on the
jugulum have often a few isolated red feathers among them. Some few spe-
cimens have white tips and inner borders of the secondaries, but this is un-
usual. The pileum of young birds has often a bronzy tint, not seen iu the
adult.

ASYNDESMUS Coues, nov. gen.

Generic Characters. — Bill as long as the head, rather longer than the tarsus,
as high as broad at the base, terminally compressed, somewhat decurved ;
almost colaptine in general aspect. Culmen much curved, tips of bill acute,
gonys straight, lateral outline of bill decidedly concave, lateral bevelling
scarcely appreciable, lateral ridge distinct, superior and inferior ridges but
slightly developed. Wings very long, when folded reaching to near the end
of the long tail ; fourth quill longest, third and fifth about equal to each other
and shorter than the second. Inner anterior claw reaching but little beyond
the base of the outer claw. Feathers of the under parts and of a nuchal col-
lar with the fibres on their terminal portion disconnected, loosened, enlarged
in calibre, stiffened, almost bristle-like, with a peculiar glistening silicious
hardness, destitute of fibrilhe whereby to interlock. Dorsal plumage imbri-
cated, with an intense metallic lustre.

Type. Picas torquatus Wilson.

The bill of this genus is quite peculiar, approaching that of Colaptes in its
length, convexity of culmen, acute tip, and slightly bevelled sides ; and re-
sembling that of Melanerpes in its sharply defined lateral ridge. The nasal*
plumuli are long and bristly but not dense. The length of the wing is ex-
cessive, and the proportions of the primaries peculiar. The most essential
feature is found in the unusual texture of the feathers of the under parts
and nuchal collar, which has thus been described : " The fibres of the feath-
ers are longer than usual and remarkably stiff. Those on the terminal third
of each feather are of the usual character at the base, or provided with fibril-
lar, those of opposite sides interlocking as in feathers generally. The termi-
nal portion, however, of the stem of the fibre is much enlarged and expanded

laterally to twice or more the diameter at the root, and converted into quite a
stiff bristle, nearly smooth or with slight indications in place of fibrillse. It is-
this portion of the feather that is colored," [Baird.] The feathers of the
nuchal collar also posses these peculiarities. The dorsal plumage is intensely
lustrous. The red about the face has a peculiar velvety aspect.

I do not find any name already proposed for this genus, which seems emi-
nently worthy of separation from Melanerpes. I had long been of this opinion
from examination of skins alone ; and since studying the bird in the field,
have become quite convinced. My name has reference to the disconnection
of the fibres of the feather.

In young birds there is hardly a trace of a nuchal collar, and the upper
parts, especially about the head, have very little lustre. The crimson fore-
head and lores are very illy defined ; nor are they trenchantly divided from
the hoary of the breast by a black area. The blood-red of the under parts
only shows in isolated patches, except perhaps on the abdomen, where it is-
more or less continuous ; the color being of various shades of gray on the
breast and sides. The feathers hardly acquire their peculiar character until
old enough to have their proper color.

Resident ; abundant: found in all situations, and in habits is quite a coun-
terpart of the eastern species it represents in Western North America.

This species has been shot at Fort Mojave by Dr. J. G. Cooper, in Feb. 1861,
when it was feeding on the larvae of insects among the Pbpulus moniliferus.
He found it very shy and wary as all the Colaptes seem to be. It doubtless
winters in the Colorado valley, though I do not think it leaves the valley to
the north and east, as I have never found it among the Whipple mountains.

" Geopicus ehrysoides Malh." was given by Prof. Baird in 1858 as a syno-
inyin, with a query, of his C hyridus. At that time there was not sufficient
material available to decide the point ; but the impropriety of the reference
has since become evident.* The bird is now well known as a common species-
of Lower and Southern California, and of the Colorado valley, and has been
brought from the Sonora line. Very numerous examples are in the Smith-
sonian from Cape St. Lucas.

" Colaptes Ayresii Aud." of Dr. Heermann's Report, as above cited, is un-
doubtedly the present species. But the true Ayresii of Audubon is a mixture
of auratus and mexicanus, more recently characterized by Prof. Baird as C.
hybridus.

TROCHILIDJE.

(48.) TrochiI/US alexandri Bo ure. and Muls.

This species has been taken in the Colorado Desert so near the western
boundary of the Territory as to render it exceedingly probable it is a bird
of the Colorado River valley, as well as of the coast of Southern and Lower
California. But I am not aware that it has actually been taken in Arizona.

Dr. Cooper tells me that the nests which he found on the Mojave River were
composed entirely of the soft white downy cotton of Platanus and Salix.

(49.) Atthis cost m (Bourc.) Reich.

A species generally distributed throughout the Territory, particularly in its
southern and southwestern portions. Not taken at Fort Whipple, though
observed some fifty miles south. From Bill William's River, Dr Kennerly, in
February ; from Fort Mojave, Dr. Cooper. Doubtless winters withiu the lim-
its of the Territory.

(50.) Selasphorcs platycercus (Sw.) Gould.

Numerous specimens seen on the sumuiit of Whipple's Pass of the Rocky
Mountains in July, feeding among clumps of wild roses. Not observed at
Fort Whipple ; but the range northward of this species, as now known, in-
cludes the whole of New Mexico and Arizona ; and further north, at least,
as far as Fort Bridger, Utah.

51. Selasphorus rpfus Swains.

Very abundant at Fort Whipple, as it is elsewhere along the whole Pacific
slope of the Rocky Mountains, and across their southern extensions into the
Rio Grande valley. Summer resident, breeding abundantly ; arrives April
10 ; remains until middle of September. Found in all situations, particularly
meadows, open copses, ravines, etc., where flowers are most abundant.

Rather sparingly distributed throughout the Territory ; chiefly in the
neighborhood of cliffs and precipices, which, I believe, it almost exclusively
inhabits.

I think there can he no doubt that the bird described by Prof. Baird, as
above, is the same as that briefly and somewhat incorrectly indicated by Dr.
Woodhouse. While encamped at Inscription Rock, July 3, 1864, I saw great
numbers of tbese Swifts ; but, as unfortunate as Dr. W., I was unable to pro-
cure a single specimen, though many passed so near me that I could posi-
tively identify them. The cbief point of discrepancy is the white rump
mentioned by Dr. Woodhouse, which does not exist in Prof. Baird's speci-
mens. But I am perfectly satisfied, in my own mind, that Dr. Woodhouse,
from the imperfect observations he was only enabled to make, mistook the
white patches on each side of the rump, which in life often reach nearly or
quite across the uropygium till they coalesce on the median line. There is a
corroboration of this view afforded by the Tachycincta thalassina. Observa-
tions of the latter in life gives the impression of a white rump ; whereas this
species has that part concolor with the back ; but the large white cottony
patches on the flanks are long and loose enough to meet each other on the
rump. Moreover the localities whence the two supposed species come are so
near as to render it unlikely there should exist two such closely allied
Swifts.
From Inscription Rock* to the San Francisco Mountains, I continually met

* Inscription Rock is a huge mass of sandstone protruding from the side of a hill, with a front of
great height perpendicular to the plain below; situate a days march west of Whipple's Pass of
the Rocky Mountains, and rather more than that distance east of the Pueblo of ZuEi. The San
Francisco Mountains are a well known locality.

with great numbers of these birds ; except along the valley of the Colorado
Chiquito River, where there were no suitable places for their habitation. It
is preeminently a saxicoliue species, and always found congregated in con-
siderable, sometimes in immense numbers, in the vicin ty of huge cliffs and
piles of rocks ; usually associating intimately and peacefully with several spe-
cies of Hirundmidce, especially Hirundo lunifrons. Its flight is very rapid and
vigorous ; similar in character to that of the common Chmtura. Its note is an
often and quickly repeated twitter, loud and shrill, quite different intone from
that of Chce.lv.ra pelasgia. It builds upon the vertical faces of precipitous
rocks.

Notwithstanding the identity of Baird's with Woodhouse's species, I do not
think that the former's name, accompanied by a definite description, should
give way to the brief and incorrect indication of Acanthylis saxutilis.

CAPRIMULGIDJE.

53. Antrostomus Nuttalli (Aud.) Cassin.

This widely distributed species, which extends from Missouri and Kansas to
the Pacific and south into Mexico, is particularly abundant throughout Ari-
zona. At Fort Whipple it is a summer resident, arriving late in April and
remaining until October. So numerous is it in some localities that around
the camp-fires of the traveller a perfect chorus of their plaintive two-s.\llabled
notes is continued all through the night, and some of the performers are usually
so near that the sharp click of their mandibles which follows each cry is distinct-
ly audible. But from the difficulty of observing them, little of their personal
habits, beyond their cries, are known to us. I never saw a single bird in Ari-
zona, though I have listened to perhaps many hundred. Their dissyllabic note
is a peculiarity which well distinguishes them from A. vociftrus.

I have been informed that the trissyllabic notes of A. vociferus have been
heard in Arizona; but I consider the statement as very improbable.

(54.) Chordeiles Henryi Cass.

Abundant throughout the Territory. At Fort Whipple a summer resident,
arriving in April and remaining until October. It is particularly numerous in
August and September.

This species, if it be really one, is not larger than C. popetue, and it otherwise
is so closely allied to the latter, as to render the separation of some specimens
a matter based upon locality rather than upon differences to be found on com-
parison of skins. The western bird presents variations quite parallel with
those of popetue ; but nevertheless the average is much lighter colored and
with more rufous about it, than usually exhibited by eastern specimens.
These remarks are founded upon examination of very extensive series of both
birds which have been at my disposal.

(55.) Chordeiles Texensis Lawr.

Common in the Colorado valley to even further north than the latitude of
Fort Whipple ; but not observed elsewhere further north than some fifty
miles south of the last mentioned locality ; and then only in summer. Ex-
tends from the Rio Grande valley to the Pacific. Numerous specimens are
in the Smithsonian from Cape St. Lucas.

A female procured at Date Creek, June 5, 1865, differs from C. Henryi as
follows : The wing from the carpus measures 7 inches instead of about 8 ;
the tail 4^ instead of 5. The throat, though the specimen is a female, is pure
white ; but there are no white bands on the tail, the lateral rectrices having
very irregular, interrupted bands of rufous, except the middle pair, which are
barred with black and mottled gray, the latter much the widest. The pri-
maries are all basally spotted thickly on both inner and outer webs with bright
rufous, which spots show a tendency to form incomplete bars. On the three
first primaries is a large spot of very light rufous, placed within 2% inches of

[March,

NATURAL SCIENCES OF PHILADELPHIA. 59

the point of the wing. The fork of the tail is less than a third of an inch. In
neither sex of C. Henryi is there any rufous mottling on the primaries ; and
thus one conpsicuous alar spot is white in hoth sexes ; and is moreover much
nearer the bases of the primaries, being 3^ inches from the point of the wing :
so that when the wing is folded the spot is anterior to the ends of the secon-
daries. The reverse is the case in C. Texensis ; and these points will always
separate the two species, even when small female C. Henryi is compared
with large male texensis. I do not know if the female texensis always has a
white throat.

I am unable to discuss the relationship of the C. branliensi* 6m., and in
adopting the name texensis I am following Mr. Lawrence's authority altogether.

HALCYONlDsE.

56. Ceryle alcyon (L. ) Boie.

Common summer resident. Arrives April 10th ; remains until November.
Generally distributed over the various streams of the Territory.

(57.) Ceryle Americana (Gm.) Boie.

Observed at several points on the Colorado River between Forts Mojave and
Yuma, which I believe is the first recorded instance of its occurrence in the
Uuited States elsewhere than in the valley of the Rio Grande.

COLOPTERID.E.
58. Tyrannus vociferans Swains.

Abundant summer resident. Arrives third week in April ; remains until
latter part of Sept. Found in every sort of locality.

Adult individuals of the same sex hardly vary appreciably in size ; and the
colors are exceedingly constant. Males average from 9* X 16-5 to 9"25 X
16-75 ; females measure about 8-75 X 16. Iris brown. Bill and feet black.
Mouth livid flesh color.

The young of the year in July and August differ materially from the adults.
The mouth and some part of the lower mandible are bright yellow. The feet
are light colored instead of black. The primaries are not attenuated near
their tips. There is no trace of the red in the crown. Tue outer web of
the exterior tail feather is barely appreciably lighter than the rest. The wing
coverts are strongly margined and tipped with pale rufous ; the quill feathers
less conspicuously edged with yellowish white. The back is nearly pure dull
brown, concolor with the head instead of being olive gray in contrast with the
plumbeous head. Below the two ages are nearly alike ; but the yellow is
sometimes so pale as to be dull sulphury white ; while the breast is rather
brown than plumbeous. The chin is always conspicuously pure white.

(59.) Tyrannus verticalis Say.

A bird which in its extensive wanderings includes Arizona, though that
country cannot be considered as properly a part of its habitat. Dr. Cooper
has taken it at Fort Mojave, and throughout Southern California. I have
never met with it at Fort Whipple, where vociferans is so very abundant.

60. Myiarchus MExicANCS (Kaup.) Baird.

Common summer resident. Arrives third week in April; remains until
middle of September. Seldom found in the pines, preferring ravines, hill-
sides, creek bottoms, etc. Some winter as high in the Colorado Valley as
Fort Mojave. (January; Cooper.) Iris brown. Mouth livid flesh color. Bill
and feet black. Moult through July and August.

At Fort Whipple .young birds were first observed early in July. Though
not mistakable for any other species, they differ notably from the adults. The
head is clear brown, in tolerably strong contrast to the color of the back, which
latter is lighter and duller than that of the adult. All the wing coverts are
so widely edged and tipped with light rufous as to give the prevailiug color

1866.]

60 PROCEEDINGS OF THE ACADEMY OF

to these parts. The reddish edging of the primaries is very broad, and takes
in more of the primaries, but is duller than in the adult. The tail differs
most ; instead of being dimidiated with clear brown and deep pure chestnut,
(the outer webs and tips being of the former color,) the whole tail is light dull
chestnut, more or less obscured by dusky towards the bases of the feathers ;
the central pair having a narrow median shaft line of this color. The under
parts are quite similar to those of the adults ; the yellow being fully as in-
tense. The bill and feet are black, as in the adult ; the mouth, however, is
bright yellow.

The males average 8*50 X 13-25. The females are generaly fully 50 X 1*50
shorter in these dimensions ; a somewhat unusual amount of difference in this
family.

61. Sayornis sayds (Bp. ) Baird.

Common throughout the Territory ; a summer resident at Fort Whipple. Is
the first of the migratory birds in spring, arriving in March ; and it also re-
mains very late, until the middle of October. Winters in the whole Colorado
Valley, and southern portions of the Territory generally. Almost exclusively
frequents open plains in stunted chaparral, sage brush, etc. ; and in some
other points of habit differs remarkably from our other Fly-catchers.

The iris is dark brown ; the bill and feet blaik, the mouth chiefly flesh col-
ored. The moult is not finished until late in September.

There is an interesting parallelism in the migrations of the smaller Fly-
catchers of the eastern and western coasts. Thus the present species arrives
at Fort Whipple among the very first of the spring migrants, just as S.fuscus
does in the middle districts of the Eastern States. Both likewise depart very
late, some remaining through October. Next in order come various species of
Empidonax : — in the East, E. acadicus, traillii, jiaviventris and minimus; in
the West, E. pusillus, difficilis, hammondii and obscurus ; which correspond
very nearly in their times of arrival and departure. Latest of all the Contopi
make their appearance : — C. virens in the East ; C. Richardsonii in the West.

This species does not habitually frequent canons, rocky gorges, secluded
banks of streams, etc., like its congener, S.fuscus; nor yet does it inhabit
forests with the Contopi and Empidonaces.

(62.) Sayornis nigricans Bonap.

A very abundant and permanent resident in the valleys of the Gila and
Colorado, and more southern portions of the Territory generally. " Winters
as high as Fort Mojave, " (Cooper.) Not found at Fort Whipple, though de-
tected a very few miles southward of that locality. On the Pacific coast it has
been found considerably north of the latitude of Whipple ; and will in all pro-
bability be found as at least a summer visitant to the latter place.

63. Contopus pertinax Cab.

Conlopus " borealis exMex." of many authors. Not Tyrannus boreal is
Sw. et Rich.

Contopus pertinax, Cab. Mus. Hein. ii. 1859, p- 72.
Very rare summer resident at Fort Whipple. A single specimen, taken
Aug. 20, in good plumage, though most other Fly catchers were in moult.
The bill above was black, the lower mandible and mouth rich orange yellow.
This young specimen differs from adult examples from Mexico in having more
brown rather than pure dark olive in the color of the upper parts, in having
the rump and upper tail coverts margined with dull ferrugineous ; all the
wing coverts and the secondaries broadly edged and tipped with the same,
palest on the secondaries ; and a wash of rufous on the under parts gen-
erally. The tail is less deeply forked.

This is a species to which are to be referred the various citations of " bore-
alts'" from Mexico; which latter species does not appear to include this
country in its range. The differences between the two are more palpable than

[March,

NATURAL SCIENCES OF PHILADELPHIA. 61

is generally the case in this group of birds. There is more of olive, and less
of pure dark brown in the upper parts. The under parts are of a nearly uni-
form soiled dull brownish olive, only a little lighter on the throat, and some-
what tinged with yellowish on the middle of the abdomen, very different from
the streaked brown breast and white throat and abdomen of horealis. The
bill is much longer though not wider than that of horealis ; bright yellow be-
low. The tuft of white crissal feathers is far less conspicuous. In pe.rtinax
the second, third and fourth quills are about equal to each other, and longest ;
the first half an inch shorter than the second ; intermediate in length between
the fifth and sixth. In horealis the second quill is much the longest, the first
and third about equal and -15 of an inch shorter than the second ; the fourth
•50, and the fifth -90 of an inch shorter than the longest. A very differently
shaped wing is thus produced. The tail of pertinax is nearly half an inch
longer than that of horealis.

The present species is one of several Mexican and Peninsular birds which
are found in upper Arizona; doubtless following the course of the Valley of
the great Colorado. It is now for the first time introduced into the Fauna of
the United States.

64. Contoi'DS Richakdsonii (Swains.) Baird.

Exceedingly abundant summer resident. Arrives in spring about May 1st,
the latest of the Fly-catchers, as does C. virens in the Ea?t. Departs third
week in September. Found in all situations, hut especially in open forests.
Iris brown. Bill and feet black; the under mandihle tomewhat lighter col-
ored. Mouth bright yellow.

The plumage of the upper parts of the young of the year is plain dull
brown, with no olive tint ; some of the feathers (chiefly those of the head
and rump) tipped with dull rufous ; which sometimes, especially on the
rump, gives the main color to the part. Below the olivaceous gray of the
adult is every where mixed with considerable dull ferrugineous ; only the
chin and middle of the belly being untinged with this color. All the wing
coverts and the inner primaries are strongly edged and tipped with ferrugine-
ous. The iris is brown ; the bill above and the feet black ; the lower mandi-
ble yellow except at tip ; the mouth orange yellow.

In examining the very lar._e series of skins I have collected on the Rio
Grande in New Mexico, and in Arizona, together with specimens from Colorado
Territory and other parts of the west, there has been made upon me an im-
pression that there are two species. By far the majority of specimens are of
the regulation Richardsonii type. A few others in the series and from very
various and diverse localities, differ in being all over of a more decided and
uniform grayish brown ; with less of olive above and with no trace below of
any sulphury olive on the abdomen ; tnis part with the throat being more
decidedly dull whit.sh than the rest of the series ; and the breast more purely
gray, in contrast to the lighter colored throat and abdomen. The bird may be
well described as a miniature of C. horealis. Prof. Baird has always, to me,
verbis et Uteris, indicated his decided conviction that there are two species in
the collection ; and we have been in the habit of designating these gray speci-
mens as Cvnio/ms Veliei, after Dr. Velie, who sent the first example from the
mountains of Colorado Territory. But the proportions of the birds appear the
same in every specimen ; and I have noticed, too, that all these gray ones are
late summer or early fall birds, and I must candidly confess my inability to
satisfactorily discern in the series a second species.

65. Empidonax pusillus (Swains.) Baird.

Moderately abundant summer resident. None of the several Empidonaces
found at Fort Whipple are very numerous ; and this is perhaps the most char-
acteristic species. Arrives- middle of April ; remains through September.
Several excellent and typteal examples of both old and young are in my col-
lection, which I have no difficulty in identifying by Prof. Baird's superb mo-
nograph.

Iris blackish brown. Legs and feet and upper mandible black ; lower man-
dible dusky flesh. No. 36945, measures 5-9 X 8-7 ; No. 36944, 6-1 X 9-2.

A young bird in my Fort Yuma collection, (Sept. 17, 1865, > differs greatly
from the adult in colors, though the proportions are accurately preserved. It
is everywhere very strongly suffused with olive, becoming olivaceous yellow
beneath, almost like flaviventris or difficilis. The middle of the abdomen, how-
ever, is rhore decidedly whitish, and the sides of the breast somewhat rufous.
The bands on the wings and the edges of the primaries are very strongly
tinged with ferrugineous, especially the former. The tail is margined with a
duller shade of the same color, as is also the under coverts of the wing near
its edge The upper mandible is black ; the lower with the whole mouth
bright yellow. The feet are brownish. But with this similarity of colors the
shape of the bill, and the proportions of some other parts will always readily
distinguish it from flaviventris or diffieilis.

The Platyrltynchus pusillus of Swainson (Syn. Mex. Birds in Phil. Mag.
May, 1827, 366,) is one of several Tyrannince which Dr. Sclater finds it difficult
to determine satisfactorily, (P. Z. S. , 1859, p. 44.) The species is, I thiuk,
most undoubtedly the same as that subsequently described and figured by
Swainson and Richardson, (F. B. A. ii. 1831, p. 144,) which Prof. Baird has
shown quite conclusively to be the species now under consideration. I have
elsewhere (vide infra) shown where I think belongs Tyrannula affinis of
Swainson's Mexican synopsis.

66. Empidonax difficilis Baird.

E. difficilis Baird. B. N. A., 1858, p. 198; name proposed in text of
flaviventris for western specimens.
Rather rare ; summer resident ; arrives middle of April ; remains until lat-
ter part of September.

Iris brown ; feet black ; upper mandible black, lower light yellow.
It is somewhat diffiunlt to distinguish this supposed species from the eastern
flaviventris.

67. Empidonax Hammondii (Xantus) Baird.

Rather rare summer resident. Arrives 1 >te in April ; remains until third
week in October.

A species readily discernible among the little North American Empidonaces
by its diminutive bill, the deep forking of the tail, and the proportions of the
primaries, independently of its peculiar shades of color. The grayish white
tips of the lesser and median wing coverts are very conspicuous. The white
margin of the inner primaries and secondaries are well defined ; but stop ab-
ruptly before reaching the greater coverts, so that a well marked area is thus
left entirely dark colored ; except on a single feather, (the innermost secon-
dary), which is margined for its whole length. Specimens hardly vary in
size ; not more than a fourth of an inch in length, and a little more in extent
The bill is almost wholly dark colored ; the under mandible being only slightly
lighter in color. The legs and feet are black. The mouth at all seasons is
bright yellow.

In the fall, as usual, the whole colors of young birds are tinged more or less
strongly with yellowish olive ; and sometimes on certain parts with pale fer-
rugineons. The back especially towards the rump is quite decidedly olivace-
ous brown ; the head not so purely biown as iu spring. The bands on the
wing, and the margins of the primaries are tinged with rufous olive. The under
parts, especially on the abdomen and flanks, are strongly olive yellow, giving
somewhat the aspect of flaviventris ; but the throat and breast remains much
as in spring.

NATURAL SCIENCES OF PHILADELPHIA; 63

Summer resident ; rare. Arrives early in April : remains until October.
Bill black above ; bright yellow below, except at its extreme tip. Mouth
yellow at all seasons. Iris brown. Subject to only very slight variations in
size.

One of the most strongly marked of our Empidonaces. Its essential char-
acters lie in the much elongated and very narrow bill ; the long tarsi ; the
tail not forked, but rather the reverse ; and the conspicuously contrasted
white outer web of the exterior rectrices. Its colors are almost precisely
those of Hammondii, but the proportions of the two birds are quite different.

There are several discrepancies between the present bird and the brief and
unsatisfactory description of Swainson above cited, as shown by Prof. Baird,
who proposes the name " Wrightii" in the event that the Mexican bird
proves distinct from that of the United States.

[Note. — Dr. J. Gr. Cooper furnishes me with the following: " Empidonax
Traillii. I have found this species west of the Mojave River and Cajou Pass,
and at Santa Barbara, in California. It was abundant at Fort Mojave : a shy
aud retiring species ; keeping in the willow and cotton wood copses of the
river bottom." Though disliking to suppose an error of identification in so
judicious a naturalist, I am of opinion that the note refers to pusillus, and not
to Traillii. Still Traillii is found in Mexico, and may very possibly ascend
the valley of the Colorado.]

MITREPHORUS Scl.

Mitrephorus, Sclater, P. Z. S., 1859, p. 44; type M. phwocercus Scl.

A genus founded by Dr. Sclater, as above, to receive certain small Tyran-
nuline forms, closely allied to Empidonax, but differing from that genus in
the elongation of the occipital feathers, and a general fulvous or buffy suffu-
sion which tinges all the colors of the species.

To the genus thus based upon M. plueocercus from Central Mexico, also
belongs the Musccapa fulvifrons of Giraud. A third species is one recently
described by Mr. Lawrence,* from Costa Rica, as M. aurantiiventris, differing
from phaiocercus in being rather smaller, the rusty fulvous of the under parts
much lighter, becoming bright orange yellow on the abdomen and sides, etc.

I have the pleasure of introducing this neotropical genus into the United
States Ornis, upon specimens taken at Fort Whipple, of a species I shall
describe as new ; but which is so closely allied to M. fulvifrons that the two
may hereafter prove to be identical.

maries, except just at their base, and the tips of greater and median coverts,

Habitat. — Fort Whipple, Arizona. A summer resident, arriving early in
May. Rare. Found in similar situations with Empidonaces.

I have before me but a single specimen of Mitrephorus fuh'ifrons, which,
judging from the rufous in the white of the wing margins, and general " feel"
of the feathers is probably an autumnal or immature bird. It was received
from Mexico through the Maison Verreaux, and labelled by those gentlemen.
From this specimen, my two examples, taken in May, at Fort Whipple, differ
conspicuously in color ; the upper parts being dull grayish brown, with hardly
a tinge of olivaceous, instead of decided fulvous brownish olive ; the lower
parts being pale fulvous, only well marked on the breast, other portions, par-
ticularly the abdomen, being nearly white ; whereas, in the specimen of fulvi-
frons, the whole under parts are very strongly fulvous, almost ferrugineous,
only a little lighter on the chin and on the abdomen, which latter is rusty
yellow instead of nearly white. The forehead and lores of my specimens
exhibit no trace of the color which has given the other species its distinctive
name.

I can, however, detect no differences whatever in size or form between the
two. I consider it as quite possible that the discrepancies above indicated
may prove to be only those of age or season. Still, a decided difference in
color does exist, sufficient to warrant me in describing the species as distinct,
for the present, at least. The range of habitat of the two is quite diverse.

No comparisons with M. phozocercus or aurantiiventris are needed.

Dr. Sclater, in instituting his species plueocercus, inclines to the opinion
that it may be the species indicated by Swainson as Tyrannula affinis. (See
citation and copy of Swainson's description, antea.) It is quite likely that
Swainson had in view some species of Mitrephorus ; but I think rather the
present species than plueocercus, as the expression "beneath pale fulvous"
hardly applies to the latter, in which the parts are very strongly colored
indeed. However, Swainson's description is so vague and meagre, that it is
hardly worth considering at all, in view of the impossibility of identifying it
positively with any species.

I use another name than that under which I first mentioned the species in
Newton's Ibis, as above ; since the species being not smaller than fulvifrons,
the name pygmceus would convey an erroneous impression regarding it.

Common summer resident. Arrives third week in April ; remains until
latter part of September. I fouud it more numerous on the Colorado Chi-
quito than among the Whipple .fountains. My specimens from the Rio
Grande are quite like those from Arizona, of the variety cauilatus Baird.

75. Oroscoptes montanus (Towns.) Baird.

It is a little singular that I never saw this species about Fort Whipple,
since it is so well known a bird of almost every portion of Arizona.

(76.) Harporhynchus Lecontei (Lawr.) Bp.

On the 30th of September, 186"), I had the pleasure of procuring the second
known specimen of this excessively rare and little known species. I found it
on a dry, barren plain, covered chiefly with mezquite and several genera of
Cactaceie, about fifteen miles from the Colorado River, just above Fort
Mojave. It was very shy and restless, fluttering hurriedly from one cactus
bush to another, till at last I shot it as it fancied itself hidden among the
thick fronds of a large Yucca. Its large strong feet admirably adapt it for
a partially terrestrial life, and it spends much of its time on th« ground,
where it runs rapidly and easily. Its flight is swift but desultory, accom-
panied by continual flirting of the tail. A few days afterward I saw several
more in the same place.

My specimen agrees exactly with Mr. Lawrence's type and description, and
presents all those differences from crissalis detailed by Prof. Baird in his Birds
of North America. Mr. Lawrence's type is from Fort Yuma. The species is
undoubtedly an inhabitant of the whole of the valleys of the Colorado and
Gila, probably not leaving these streams for mountainous regions.

(77.) Harporhynchus crissalis Henry.

Colorado and Gila valleys. Not observed at Whipple. " A few keep about
Fort Mojave." (Cooper.)

The second known specimen of H. crissalis is in the Smithsonian, from
Fort Yuma, the original locality of U. Lecontei. The range of both species is
doubtless quite identical ; and the fact that, though thus associating, they
still preserve intact their distinctive fea ures, is a strong argument in favor
of their separation. I have myself examined Dr. Henry's type specimen of
//. crissalis, and find it sufficiently distinct from Lecontei, whatever may be its-
relations to the coast species rcdivivus. •

The "? Harporhynchus curvirostris " mentioned by Dr. Heermann in his
Report, as having been seen near Tucson, Southern Arizona, was undoubt-
edly either this or the preceding species.

79. Sialia mexicana Swainson. •

Permanent resident. Exceedingly abundant. In its familiarity and other
habits exactly replaces S. sialis of the east.

Specimens vary in every conceivable degree between the dullest colored
young female and the high plumaged spring male. In immature plumage
some examples much resemble S. artica ; but there is always discernible a
dorsal patch somewhat differently colored from the rest of the upper parts.
The shade of blue differs in equally mature males, being sometimes of a pur-
plish tint, and rarely the blue so invades and interrupts the dorsal chestnut as
to render the boundaries of the latter quite undefinable.

80. Sialia arctica Swainson.

Rather uncommon. Noticed only late in the autumn and in the winter ;
not observed to breed at Fort Whipple, and I think it is there chiefly a winter
visitant. Has been taken as far South as Fort Yuma. Audubon s figure of
the female is quite incorrect. The species differs conspicuously from mexi-
cana in its habits.

88. Dendimeca Graci* Cones.

Dendroica Graciie, Coues MSS., in Baird's Rev. Amer. Birds, Apr.,
1865, p. 210.

Description. (Orig. No. 1293, rj\ Apr. 26, 1865, Fort Whipple.) Bill shorter
than head or tarsus, about equal to the middle toe without its claw ; the cul-
men convex, the gonys very slightly so, the commissure a little curved.
Wings of ordinary length for this genus ; second and third primaries about
equal and longest ; first and fourth about equal to each other, and but little
less than the second or third. Sometimes the first four hardly differ appreci-
ably in length. Fifth -20 of an inch shorter than fourth. Tail of ordinary
length ; a little rounded, the outer lateral rectrices being a tenth of an inch
less than the median pair. Tarsus a little longer than the middle toe and claw.
Lateral toes short, equalling each other in length : the tips of their claws fall-
ing short of the base of the middle claw. Hind claw much longer and mor«
curved than the others ; about as long as its digit.

Adult spring plumage. — Entire upper parts ashy gray, with a tinge of blui-h
slate; the interscapular feathers conspicuously, and the upper tail coverts oh-
soletely streaked with black. A broad stripe of bright yellow passes from the
nostril over the eye, changing abruptly into pure white as it passes over the
posterior eanthus. Edges of upper and lower eyelids yellow ; that of
the latter more or less confluent with a small 'semilunar patch of yel-
low just below the eye. Chin, throat and upper part of the breast broadly
and uninterruptedly bright yellow, bordered on each side by streaks of black,
which separate it from the slaty gray of the sides of the neck ; more anteriorly
a black line cutting off the infra-ocular yellow crescent from the yellow of the
throat. Lores between eye and bill black, and the feathers of the crown
centrally black, most so on the forehead, less so on the occiput, producing an
appearence much like that of Afyiodioctes canadensis. Lesser and median
wing coverts colored like the back, greater coverts like the primaries ; both
median and greater conspicuously tipped with white, the former much the
most broadly. Primaries dusky ; the first three or four with an exceedingly
narrow margin of white ; the rest and the secondaries with somewhat pale
edges. Tail like the wings ; the outermost lateral rectrices white, except
their shafts, and a very small area at the base of the inner web, and the outer
web for half its length from the base ; next feather similar, but the dusky
area twice as large ; the third has only a small, somewhat triangular spot of
white near the end of the inner web. The under parts, from the termination
of the trenchantly defined yellow of the breast, are white ; immaculate on the
centre of the abdomen ; thickly streaked along the sides with large, partially

blended, black lines. The iris, bill and feet are black ; the soles of the latter
dirty yellow.

Young of the year. The slate gray of the upper parts is strongly tinged with
olivaceous, least marked on the rump. The black streaks of the crown and
interscapular region are so obsolete as to be scarcely discernible. The yellow
of the head and throat has about the same extent as in the adult, but the
tint is much paler, and it is not edged along the sides of the breast and neck
by black streaks. The black lores are poorly defined. The white tips of the
greater and median wing coverts are grayish rather than pure white.
The strongly defined, black, lateral streaks of the adult are replaced by more
or less obsolete and semiconfluent, brownish black ones, and the abdomen,
crissum and circumanal region are rather ochraceous than pure white. The
bill and feet are lighter colored. The white on the tail feathers does not dif-
fer materially from that of the adults. Between the extremes of color, as
thus characterized, are to be found every gradation in amount of slatiness and
olivaceous, of distinctness of the black lateral streaks, and intensity of
yellow.

Variations. In a series of over twenty specimens of all ages and seasons, I
find examples varying from 4'9 to 5-20 in length, and to a corresponding de-
giee in extent of wings. The average dimension is 5*00 X 8-00 X 2*60. In-
dividuals of the same age and season hardly vary appreciably in color ; some-
times the black streaks of the crown show a tendency to become segregated on
each side as a margin to the superciliary streak, leaving the centre of the
crown immaculate, or the black may occupy the whole crown almost to the
exclusion of the greyish slate. The yellow and white are alwnys trenchantly
separated on the breast, and a black border always divides the yellow chin
from the yellow on the side of the head. The interscapular region may vary
in its amount of streaking. The greater coverts are sometimes edged, as well
as tipped with dull white.

Remarks. D. Gracice is exceedingly unlike any other North American
warbler. Its upper parts bear a striking resemblance to those of Myiodioctes
canadensis. It agrees with dominica (= superciliosa) in the yellow throat,
but is otherwise quite different from that species. It is closely allied to Baird's
new Porto Rican species, D. Adf-lu'da-, but this latter has the yellow extended
over the whole under parts, and otherwise differs materially in some points of
form as well as color.

Habitat. First met with July 2, 1864, in the pine woods covering the sum-
mit of Whipple's Pass of the Rocky Mountains. I saw no more on my journey
into Central Arizona, till again among pines at Fori Whipple, where it is a
very common bird, being in fact as abundant as virens or striata in our eastern
forests. It will doubtless be found in the forests of the San Francisco Mount-
ains. Its range seems to include all the pine tracts of New Mexico and Arizo-
na, from near the Valley of the Rio Grande to that of the Great Colorado. It
breeds about Whipple ; how far south it may go in winter into Mexico I am
unable to say.

Arrives at Fort Whipple Apr. 20, and remains until third week in September.
Almost exclusive'y pinicoline. An active, industrious, noisy species, posses-
sing marked muscicapine habits, Hying out from its perch to capture passing
insects. Like many other diminutive birds, it ambitiously prefers to inhabit
the tallest trees. It has several notes, one of which is the ordinary "tsip,"
emitted at all times by both old and young of most small insectivorous birds.
Its song proper, only heard in spring, consists of two or three loud, sweet
whistles, somewhat slurred, followed by several continuous notes resembling
" chir-r-r " in a wiry but clear tone. T^liis note is of much power for the size
of the bird. Another song, uttered when pairing, is much like that of Seto-
l>ha(ja ruticilla. The birds mate as early as May 1st, and doubtless raise two
broods, as I have found newly Hedged young as late as the middle of August.

89. Dendrosca nigrescens (Towns.1) Baird.

Common ; chiefly spring and autumn migrant ; but a few breed. Arrives
about Apr. 20, remains until late in September. Chiefiv pinicoline, and in
-other habits as well as in voice is exceedingly similar to D. GrdcicB.

This species is by no means so peculiarly a Pacific one as has generally
been supposed.

DO. Dexdrceca occidentalis (Towns. ) Baird.

Very rare. Summer resident. A single specimen of this little known
species, taken early in September in thick scrub oak bushes. It measured
4-9 X 7*7. In this immature state the dusky olivaceous extends over the
whole upper parts, deeply tinging the pure ash of the rump of the adults with
a somewhat lighter" shade of the olivaceous of the back, and extending for-
ward on the crown nearly to the front, where it gradually lightens by becom-
ing more and more mixed with yellow. The sides of the head are clear yellow,
only slightly soiled by olivaceous, and the chin and throat are the same, fad-
ing insensibly on the breast into the dull greyish white of the under parts
generally. The sides show indications of streaks, very obsolete, however, and
have a slight wash of grayish olivaceous. There is no black whatever about
the head or throat, and the back is only very obsoletely streaked with that
color. The greater and median coverts are conspicuously tipped with white.

A suite of specimens illustrating all the changes of plumage of this species,
so closely allied to virens, chrysopareia, etc., is still a great desideratum.

91. Dendececa Auddbonii (Towns.) Baird.

Exceedingly abundant ; spring and autumn migrant. A few possibly breed.
Some remain all winter. "Numerous at Fort Mojave in winter," (C>oper.)
Very numerous from Apr. 20th to May 10th, and during the month of Octo-
ber, in which seasons the cotton-woods and willows of the creek bottoms are
filled with the birds, which are also found in every other situation more or
less abundantly.

Specimens in very high spring plumage have the black of the breast quite
pure, and unmixed with slate in any portion of its extent, contrasting sharply
with the whole width of the posterior edge of the yellow throat. The streaks
on the sides and flanks are very narrow and distinctly defined. The intersca-
pulare is very thickly streaked with black. The greater wing coverts are so
broadly edged with white as to leave only a small space on their inner webs
dusky. The yellow crown is intense in color, small and sharply defined, and
there is much black on the front and lores. For so small a bird, the species
varies much in size. Seasonal and sexual changes of plumage are quite ho-
mologous with those of D. coronata.

Specimens at all seasons and ages have the white eyelids distinguishing the
species from Philadelphia. Autumnal examples, though possessing the grayish
ash throat just as in spring individuals, have the nape and crown so much
washed with olivaceous as to be nearly concolor with the back. Iris brown-

1866. (Fort Whipple.)
This interesting little species, recently described, as above, does not seem
to be very rare in northern and western Arizona ; though so far as I am aware,
five specimens taken by Dr. Cooper, at Fort Mojave, and three by myself at
Fort Whipple, are the only ones known to exist in any collections. At Fort
Whipple it is a summer resident ; arriving the second or third week in April,
and remaining till latter part of September. It mates from the 20th to the
30th of April : the young appear early in May. In habits I think it inclines
toward the Geotklypi rather than to the species of the genus to which it belongs ;
showing a decided preference for thickets and copses rather than for high open
woods ; and also like the Geothlt/pi, it is an exceedingly shy and retiring spe-
cies. The difficulty of observing and procuring it thus caused is doubtless the
reason why it has remained so long undetected. It is in all its motions ex-
ceedingly active and restless ; as much so indeed as a Polioptila, to which its
co'ors bear such an intimate resemblance. The only note I have heard is a
quickly and often repeated " tsip, " as slender and wiry as that of a gnatcatcVer.
But Dr. Cooper tells me he has heard a rich and pleasing song, in the spring,
the little performer being mounted on the top of some mezquite or other bush.
I have never met with the nest ; but I think it will be found, not on the
ground, but in the crotch of a thick busb. Dr. Cooper thinks the bird does
not breed in the Colorado Valley ; but retires to mountainous regions, which
is most probable. I have found it breeding at Whipple. Specimens measure
from 430 to 4-60 in length, and from 7 to 7£ in extent. The iris is black : the
mouth flesh color, the legs and feet duty leaden blue. The young bird, just
fledged, wants the chestnut crown of the adult, and the throat and breast are
pure milk white, being without the faint ochraceous tinge that is just barely ap-
preciable in the adult ; the wing coverts are pale gray, and edged with ochra-
ceous or pale rufous. The chestnut rump is present.

Dr. Woodhouse's type of P. azarce, now in the Smithsonian, was from the

Summer resident ; rare. Arrives middle of April ; leaves late in Septem-
ber. Iris brown, mouth yellow, legs and feet light blue. This species has an
extensive breeding range, from at least as far north as Laramie Peak.

In high spring plumage, the head and throat become intense scarlet, deep-
est on the crown. The middle of the back is uninterruptedly pure black, and
the rump is bright chrome, rather than gamboge yellow. The median and
greater coverts, however, and the outer edges of some of the inner second-
aries seem always tipped with dull yellow. The extent of red on the breast
varies much. In the female, the head is merely a little more yellowish olive
than the color of the back ; the greater coverts and inner secondaries are
tipped with white instead of yellow.

Inhabits rather open country, in preference to densely wooded regions. It is

1866]

a shy, wild and restless bird. The fact that it has a superb song, powerful
and finely modulated, may give a hinr as to its proper place in the series. It
seems to me to have little affinity with the forms with which it is usually
grouped.

106. Myiade'stes Towjtsendii (And.) Cab.

Rare summer resident. This species has-, like the Phanopepla nit ens,
eminent vocal powers, producing a rich, sweet, finely-modulated song.

It is an interesting fact, taken in connection with its highly-developed lower
larynx, that the young Myiadestes is spotted all over exactly like a young
thrush. Numerous individuals which I studied several years ago differed from
the adult precisely as a youug Tardus migratorius does. Another marked
Turdine character is seen in the " booted '' tarsi — very different from the
scutellations which obtain in Phcenqpepla, with which Myiadestes is usually
in'imatfly associated in classifications. Whether Phcenopepla is to be grouped
with the Atnpelidee or not, I think there is little doubt that Myiadestes is
typical of an aberrant subfamily Myiadestince, of Turdidee.

Some young birds, taken early in September, differ from eastern examples
in having the wing half an inch shorter ; the tail a fourth of an inch less.
The bills of both are quite identical, while the feet are even larger and
stouter. The upper parts are of a brighter, clear brown, instead of grayish
brown. The wing and tail coverts, and the outer margins of the secondaries
and inner primaries, are edged and tipped with dull ferru.gineous. The whole

trace of the recurving and serration of the outer web of the first primary.

Ibis, April, 1865, p. 164.
V. gilvus, Cooper and Suckley, Nat. Hist, of Washington Territory, 1860,
p. 188.

Sp. Ch. — Size and general aspect of V. gilvus. Upper parts olive ash,
decidedly less olivaceous than in gilvus ; so that the back is nearly concolor
with the head. Below whitish scarcely appreciably washed with yellowish,
and only along the sides ; the median portions of the under parts pure white.
Other markings less distinctly defined than in gilvus. Wing more rounded :
fourth primary longest ; third and fifth equal to each other and nearly as
long; second much shorter than the sixth; hardly exceeding the seventh.
First (spurious) primary decidedly longer than in gilvus (-10 to -15 of an
inch.)

Habitat. — Rocky Mountains to the Pacific. Common summer resident at
Fort Whipple, arriving in April and remaining until October.

Comparisons. — All the very numerous specimens of Vireo " gilvus " from the
Pacific slope of the Rocky Mountains constantly differ from the eastern type
by the quite appreciable characters expressed in the preceding diagnosis.
These differences, though slight indeed, are quite tangible, and, in a group
so little liable to variation as the Vireones, are very probably indicative of
specific distinction.

The most notable distinction is found in the proportionate lengths of the
primaries. All eastern gilvus that I have seen have the third quill longest,
or the third, fourth and fifth about equal and longest, the second being equal
to or longer than the sixth. In the present bird the fourth quill is decidedly
longest; the third and fifth successively a little shorter, while the second is
about equal to or but little longer than the seventh, never equalling the sixth.
The spurious primary is from one to nearly two-tenths of an inch longer
than in gilvus. In addition there is a decidedly ashy rather than olivaceous
wash on the upper parts, rendering the crown and back nearly concolor; and
there is less sulphury yellow on the under parts.

Whether these differences be "specific" or not it is certainly well to define
them, and give to the species or race a name by which it may be recognized.
Prof. Baird first called attention to these discrepancies, suggesting the name
I have adopted in thus characterizing the new species.

In the discrepancies in the proportionate lengths of the quills of this
Species and V. gilvus, there is discernible a striking analogy with the dis-
tinctive characters of Carpodacus californicus as compared with C. purpureus.

PROCEEDINGS OF THE ACADEMY OP

In both C. californicus and V. gilvus the longest primary is advanced by one
over their eastern representatives, the third and fourth being respectively
longest, instead of the second and third; and in both, the first quill is abbre-
viated.

116. Virzo plombecs Coues, nov. sp.

Sp. Ch — First quill spurious ; second equal to or little longer than sixth ;
third longest: fourth and fifth successively but little shorter. Entire upper
parts, including crown, sides of neck and line from below under eyelid to
bill, uniform pure plumbeous or ashy gray, with no shade of olivaceous
whatever, except a faint wa?h of 1 his color on the extreme uropygium.
Superciliary streak passing from nostrils over and around eye, including
under eyelid; two conspicuous bands on wings; outer margins of all
secondaries and most primaries ; both margins of all rectrices except median
pair ; and entire under parts, pure white. Sides under the wings and inferior
wing coverts faintly washed with light sulphury olivaceous. Lores blackish
ash. Bill and feet bluish black; farmer very robust. Length 5-75 to 6-10
inches and hundredths : extent 9-75 to 10-25 ; wing from carpus 2-90 to 3-10 ;
tail 2-50 ; bill -45 ; tarsus -65 ; middle toe and claw -65 ; exposed portion of
spurious primary -75 ; a third the length of the second primary.

Habitat. — High central plains to the Pacific. Laramie Peak. Especially
abundant in Northern Arizona. By far the commonest Vireo at Fort Whip-
ple ; a summer resident ; arrives April 25 ; remains through September.

Description.— (Ho. 40,703, J\ May 17, 1865, Fort Whipple. Type). The
bill is large and very robust, being especially deep at the base, where it is
compressed and much higher than broad The ridge of the culmen is well
defined; its outline very convex, the tip of the bill being much decurved,
strongly hooked and notched. The commissure is a little curved ; the gonys
slightly convex and ascending. The tarsus is about as long as the middle
toe and claw. The tip of the outer claw a little surpasses the base of the
middle one; which point the tip of ihe inner claw falls a little short of.
The hallux is considerably longer than its claw ; and, with its claw, is about
as long as the middle toe without its claw. The wings are long, reaching,
when folded, a little beyond the middle of the tail. The third primary is
usually longest; but the fourth and fifth are so near it that often there is no
perceptible difference. The second is about as long as the sixth, or inter-
mediate between it and the fifth. The spurious primary is a third as long as
the second. The tail is moderately long ; the rectrices obliquely truncated
and a little pointed at their tips.

The bill is deep bluish black, the posterior half of of the lower mandible
often light bluish horn, in marked contrast ; the feet and claws are dusky
leaden blue. The mouth is livid bluish white; the eyes reddish brown.
The back is plainly plumbeous, like the head ; and only for a brief space on
the rump is there a faint tinge of olivaceous ; the upper tail coverts, again,
being like the back. A pure white streak begins at the nostril, and runs over
the eye as a superciliary line; not extending, however, beyond the eye, but
turning down around it at the posterior canthus, where it is continuous with
the very extensively white under eyel'd ; this white of the under eyelid being
separated at the anterior canthus from the superciliary streak by the blackish
ashy lores. The white lower eyelid is separated from the white of the chin
by an extension forward of the plumbeous of the side of the neck to the
base of the inferior maxilla, where it merges into the dark lores. The lesser
wing coverts are like the back. The median and greater are more like the
primaries in color ; very broadly tipped and more narrowly edged with
pure white. The inner primaries and all the secondaries are edged with
white, except towards the apices of the primaries, and towards their bases,
where the edging is rather olivaceous than pure white. The inferior aspect
of the folded wing shows a white central area, caused by the coalescence of

[March,

NATURAL SCIENCES OF PHILADELPHIA. <D

the, quite broad, dull white inner margins of the primaries. The rectrices
are very broadly edged on both their interior and exterior margins with pure
white; which decreases in width on successive feathers till reduced to a
minimum, or almost obsolete on the median pair. The bird is pure white
below, except a faint wash of very pale sulphury olivaceous on the sides and
flanks. The white of the breast is a little encroached on by an extension of
a light shade of the plumbeous of the sides of the neck.

Variations. — Specimens taken in July and August, in very worn and faded
plumage, have the upper parts dull grayish brown instead of clear plumbeous,
the olivaceous of the rump barely appreciable, and that of the sides very
faint. The white margins of the wings and tail are either entirely wanting
or reduced to a minimum. The markings of the sides of the head are more
indistinct. In this state of plumage, however, it. cannot be malidentified ;
for it is even more unlike any other North American Vireo than when in per-
fect condition. Specimens vary to a moderate degree in dimensions, but the
colors of equally mature specimens are remarkably constant.

Remarks — The relationships of this species are decidedly with V. solitarius ;
sharing with that species and flavifrons, etc., the compact stout form, robust
and short bill, etc. The coloration of the head is very similar to that of
solitarius, but the other differences are too great to render necessary any com-
parison between the two. Vireo plumbeus is the plainest-colored species
except V. vicinior, infra, as well as one of the largest and stoutest species of
the United States. The name is peculiarly expressive of its most striking
feature.

This is the species referred to by me in Newton's Ibis for April, 1865, page
164, as " Vireo, most like solitarius."

117. Vireo vicinior Coues, nov. sp.

Sp. Ch. — First primary spurious ; half as long as second ; second very
short, about equal to eighth or ninth ; fourth, fifth and sixth longest; third
but little shorter ; the wing thus being made short and much rounded. Tail
very long ; as long as the wings ; decidedly rounded ; rectrices with rounded,
not acute tips. Bill very short, but robust and deep at base. Tarsus much
longer than middle toe and claw ; toes all short ; the outer about equalling
the inner, much shorter than the middle toe without its claws. Entire upper
parts with sides of head and neck dull plumbeous, gradually gaining a tinge
of olivaceous towards rump. A narrow white ring around eye. No dis-
tinctly defined stripes on side of head, nor dark lores. Wing coverts, quills
and rectrices very slightly, if at all, bordered with white. Below entirely
pure white ; a hardly appreciable tinge of the slightest possible shade of
sulphury olivaceous on sides under wings. Bill and feet horn bluish black.
Length 5-70; extent 8-60; wing from carpus 2-50; tail the same : exposed
portion of first primary -75; of second 1-50; bill -36; tarsus -70; middle
toe and claw -52 ; inner do. -35 ; outer do. *42.

Habitat. Fort Whipple, Arizona. Type and only known specimen No.
1507 of my collections, (40,697 Smithsonian Register,) adult male, May 24th,
1865. Very rare ; probably a summer resident, wintering in the Gila and
Lower Colorado valleys, or in Sonora.

Description. — The bill is short, but quite stout, very deep at the base,
where it is compressed and higher than broad ; the culmen very regularly
convex in outline from the base to the moderately decurved, hooked, notched
tip. The wings are short and remarkably rounded, the spurious primary so
long as to be half the length of the second quill; which latter equals the
eighth ; there is but very little difference in length between the third, fourth,
fifth and sixth ; the first and last named, especially the former, being a little
less than the other two. The tail is very long, equalling the wing from the
carpus, and somewhat graduated ; the lateral rectrices being -20 of an inch
shorter than the median pair; and all are rounded at their extremities. The

76 PROCEEDINGS OF THE ACADEMY OP

tarsus is of moderate length ; decidedly surpassing the middle toe and claw.
The toes are all rather short. The tip of the outer claw just reaches the base
of the middle. The inner toe is remarkably abbreviated, the tip of its claw
falling much short of the base of the middle one.

Above, the bird is of a dull ashy or leaden gray, like plumbeus, but rather
duller ; which color on the back, and, to a less extent on the wing coverts,
acquires an appreciable tinge of olivaceous, most marked on the rump.
There is a narrow white ring entirely surrounding the eye, formed by the
edges of the eyelids alone. The lores are not dusky, but somewhat lighter
colored than the surrounding parts ; and the sides of the head have no
definite streaks of color. The gray of these parts fades so insensibly into
the white of the chin and throat that it is impossible to appreciate a divid-
ing line ; and the same is the case with the sides of the neck and breast.
Under the wings, the wash of olivaceous on the sides of the body is appre-
ciable, but it is very faint and pale. The greater coverts are narrowly tipped,
and the outer margins of some of the primaries slightly edged with whitish.
There is nothing of the definite white seen in plumbeus, though the whitish
area on the inner aspect of the wing is much the same. The outer edge of
the exterior tail feather is narrowly white, but the others are plain dusky.
The iris is brown; the mouth livid white; the fauces pinkish ; the feet and
bill dark bluish horn.

This is a most peculiar Vireo, totally diverse from all others of North
America. The shape of the wing, character of spurious primary, length of
tail and abbreviation of the inner lateral toe, give it an unusual shape. It will
be noticed that the colors of the species are almost exactly those of
plumbeus; but that in form the two birds are widely diverse. It is a smaller
species than plumbeus, but its greatly elongated tail make the total lengths
of the two nearly the same. The following antithetical diagnoses will
readily separate them : —

V. plumbeus. — Wing (average) 300; tail 2-50. Spurious primary -75; a
third the length of the second primary ; the latter intermediate between
fifth and sixth. Tail about even ; rectrices with obliquely truncated tips.
Tarsus as long as middle toe and claw ("65). Tip of inner claw almost
reaching to base of middle one. Wing coverts, quills and tail feathers
broadly edged with pure white. Sides of head parti-colored, with distinctly
defined stripes. Lores dusky, interrupting the broad white circumocular
ring at anterior canthus.

V. vicinior. — Wing 2-50 ; tail fully as long. Spurious primary -75 ; half
the length of the second ptimary, which latter is intermediate between eighth
and ninth. Tail decidedly graduated, the feathers with broadly rounded
apices. Tarsus longer than middle toe and claw, (as -70 to *52). Tip of
inner claw falling much short of base of middle one. Wing coverts, quills
and tail feathers very narrowly, if at all, edged with dull white. Sides of
head unicolor, unstreaked; the lores plain grayish white, not interrupting
the continuity of the very narrow circumocular ring.

It is unnecessary to compare vicinior with any other species, it is so very
dissimilar from them all. With but a single specimen, I cannot now give its
variations, though these are doubtless parallel with those of plumbeus. The
species must, I think, be exceedingly rare, or I should have met with others.

(118.) Vireo pusillus Coues, nov. sp.

Sp. Ch.— Amoug the smallest of the genus, in form and general aspect re-
sembling V. Belli. Above grayish ash, becoming more or less ashy olivace-
ous on tbe back ; not more so on the rump than elsewhere. Below pure
white, including under wing coverts; on the breast sometimes a faint suffusion
of the lightest possible shade of brownish gray; sides under the wings mod-
erately tinged with sulphur yellow. A narrow short superciliary streak ; edges
of eyelids, two bands on wings and narrow margins of outer border of wings

and tail, dull white ; on the latter tinged with olivaceous. Bill as in V.' Belli.
Exposed portion of spurious quill about half as long as second. Fourth pri-
mary longest ; third and fifth about equal to each other, and but little shorter
than fourth ; second about equal to eighth. Tail very long, equalling the
wing; rectrices quite narrow, with acuminate tips. Tarsus long, much ex-
ceeding the short toes ; outer claw surpassing, inner about equalling the mid-
dle toe without its claw. Length (approximately correct only) 5-00; extent
•7-25. Wing 2-15 ; tail about the same. Bill -34 ; tarsus -65 ; middle toe and
claw -50 ; outer do. -42 ; inner do. '39.

Habitat — Lower and Southern California, and probably Sonora, at least as
far north as near Fort Whipple. Cape St. Lucas, Xantus. Fort Mojave, Cooper.
Fifty miles south of Fort Whipple, Coues ; breeding abundantly in the last
mentioned locality. Never observed at Fort Whipple.

Description.— (No. 16,954, Smiths. Register, $, Cape St. Lucas.) The bill
is shaped exactly as in V. Belli, and is similarly colored; being light horn
blue, the lower mandible nearly white ; the former color fading into reddish
brown in drying. The iris is brown, the legs and feet dull leaden blue. The
color of the upper parts is a plain dull ashy gray on the head ; tinged with
grayish olivaceous on the rest of the upper parts ; but quite unlike the olive
green of Belli. Below the pure white of the under parts is slightly obscured
by a wash of barely definable grayish brown across the breast ; and a light
shade of sulphury olive tinges the sides under the wings. There is no ap-
proach to the bright sulphur yellow which so strongly tinges the whole under
parts of Belli, especially the flanks and circumanal region ; and invades the
under wing coverts, which in pusillus remain white. The markings on the
sides of the head are quite identical ; and the edging of the wings and tail is
similar in amount and in tint. The following are the differential points in
the diagnoses of the two species, comparison being made with Audubon's
type specimen.

V. Belli. Spurious primary two-fifths the second primary; third longest;
second a little longer than seventh. Wing much longer than tail. Color
above olive green, whole under parts except the throat strongly tinged with
sulphur yellow.

V. pusillus. Spurious primary half as long as the second ; fourth longest ;
second equal to eighth. Wings and tail equal in length. Color above grayish
olive. No sulphur yellow below except a slight wash along the sides under
the wings.

The numerous specimens collected are of the var. leucogaster, as defined by

I have never seen the Thryothorus Berlandieri from Arizona ; but think it
probably will be hereafter detected, particularly near the New Mexican boun-

species are described from New Leon, Mexico.

Troglodytes tedon, Idem, op et loc. cit.

Very abundant ; summer resident. Arrives April 20 ; remains until Oc-
tober.

Dr. Cooper informs me that so far as he knows this species never recurves
the tail over the back, a habit so characteristic of eedon. I have myself
noticed hundreds of individuals, and do not now recall an instance where
this peculiar attitude was assumed. Parkmanni has always seemed to me to
be a shyer, less familiar, more retiring and wood-loving species than its east-
ern representative; and though the measure of the song is the same, yet in
tone and volume I have often thought it sounded a little different from the
familiar trill of sedon. If some of these points of habit could be substantiated,
they would go far towards eking out the lather slim diagnosis upon which
the species now grounds its claim to recognition.

Dr. Heermann very wrongly says that " T. americanus Aud." is " abundant
in the wooded portions of the country. ,: We might suppose he had mistaken
Parkmanni for this species, did he not also give T. fedon&s being abundant
too.

Troglodytes (Anorthura) hyemalis Vieill., a bird of the eastern province, has

black; hard parts of mouth livid blue, soft parts flesh colored. The color of
the under parts varies greatly from a very pale fulvous, almost white, to a de-
cided ferruginous, almost like canadensis. Sometimes the under parts are
smoky brown, as in Picus Harrisii from California and Oregon.

(129.) Sitta canadensis Linnaeus.

Rare; perhaps only accidental. (Fort Yuma, Ives.) Not met with by me.
Dr. Cooper never saw it at Fort Mojave.

though it is generally distributed over the Territory. Dr. Kennerly procured
it very near the present site of Fort Whipple.

129. Lophophanes inornatus (Gamb.) Cass.

Winter resident chiefly; but some doubtless remain through the year,
breeding in the neighboring mountains. Not very abundant Emphatically
an evergreen oak species, eschewing the pines, and frequenting open hill-
sides.

Iris black. Bill black ; horn blue along its commissural edges and at base.
Feet deep leaden blue.

130. Lophophanes Wollwebkri Bonap.

Permanent resident; common, more so at least than the preceding. Usually
semi-gregarious except when breeding. Found in all situations; but
chiefly affect the oak thickets, and the chaparral of open hillsides. Generally
distributed through the Territory, and extending southward into Sonora.

131. Pcscile montands (Gamb.)

Resident throughout the Territory, more particularly its pine tracts. No-
where very numerous. The only species of black capped and throated Tit-
mouse ascertained by me to inhabit the Territory.

The American black-capped Titmice seem to me generically distinct from
Linnseus' type of Parus ; while they are entirely congeneric with /'. palustri*
of Eutope, Kaup's type of facile.

P. seplentrionalis is recorded from the Southern Rocky Mountains, and may
hereafter be added to the Whipple list. (Fort Massachusetts, Dr. Peters,

the Territory.

133. Psaltriparus pi.umbf.us Baird.

Resident and very abundant at all seasons. Decidedly gregarious, and, ex-
cept when mated, always found in '-flocks" of from five or six to as many
as fifty or more; active, restless and noisy, familiar and unsuspicious. Es-
chews pines, and keeps entirely in the thick shrubbery of the hillsides, or the
denser brush of creek bottoms and ravines.

No. 752 and others; iris bright yellow. No. 753 and others; iris dark
brown This difference seems entirely accidental, and not dependent upon
age, sex or season.

The original types of the species described as Psaltria plumMa, by Prof.

135. Hesperphona vespertina (Cooper) Bonap.

Chiefly a more northern and coast species ; but extending as far south as
the table lands of Mexico. It is undoubtedly a component of the Whipple
Fauoa, though I never succeeded in detecting it in that locality.

136. Carpodacus Cassini Baird.

Common ; resident. A species conspicuously different from purpureus in
habits as well as in form and color. Its range of habitat is quite diverse ;
and I have seen specimens taken during the breeding season, from the Table
Lands of Mexico. "Extends west to the eastern slope of the Sierra Nevada."
{Cooper.)

The difference in the tint of the red of the males, and its distribution on
the under parts would alone readily distinguish it; independently of its
larger size, large long bill, different proportions of primaries, etc., which lat-
ter features will always serve to separate females and immature birds.

My specimens range from 6-4 x 10*9 to 6 7 X H"4. Iris brown ; legs and
feet brownish black ; bill above deep horn blue, below flesh color more or
less obscured by dusky. Very young birds of either sex have an ochraceous
or light rufous suffusion over the whole body, most noticeable below. The
streaks are more numerous and less sharply defined.

Carpodacus '' calif or ni cus"! Coues, Newton's Ibis., Apr., 1865, p. 164,
(errore pessimo.)
Very abundant. Permanent resident, but most abundant in spring and fall.
Eminently gregarious. Found in all situations. In spring keep mostly among
thickets of Salix and Populus, on the young buds of which they chiefly feed.

The shade of red in equally adult males differs most remarkably. Immature
males, in the late fall and winter months, show every possible gradation, from
a plumage indistinguishable from that of the female to that of high spring
condition ; in which, also, the color of the throat, breast, crown and rump
ranges from an intense crimson to a light rose red, almost pink ; sometimes a
bronzy tint is quite apparent. Young birds just fiora the nest diffVr in being
much more thickly streaked below, the streaks themselves narrow and quite
sharply defined, contrary to the general rule among young Fringillidse. The
wing coverts, secondaries and tail feathers are broadly edged with dull rufous.
The crown and back are obsoletely streaked. The preceding relates to June
and July birds. A common autumnal condition is to have the whole body,
but particularly the under parts, washed wiih light rufous or ochraceous, in
which the broad streaks are numerous and semiconfluent.

I have shot '• Buriones " all the way from the Rio Grande, through New

slightest indication of another species tending toward purpureus or californicus.
The latter species seems to be exclusively a coast bird.* At the same time
frontalis is exceedingly different from the C. Iwmorrhous of Mexico.

Chrysomitris (Pseudomitris*) psaltria, Cassin, Pr. A. N. S., Philadelphia,
1865, p. 93.

Abundant. Summer resident. Arrives last of April, remains until middle
of September. Males are in dull plumage of females in August. Decidedly
gregarious in autumn. Feed almost exclusively on buds and seeds. Probably
less numerous in the southern portions of the Territory.

In typical adult males the pileum is black, but this color does not extend below
*he eyes; the lores and auriculars being olive like the back. Upper parts, ex-
•elusive of the wings, clear olivaceous, somewhat more yellowish, and with con-
cealed white on the rump. The back may be somewhat marked wjth blackish
sp >ts, though rarely to the extent represented in Audubon's plate. The wings
are black, though some of the lesser and median coverts are tipped with olive.
The greater coverts are so broadly tipped with white as to form a conspicuous
transalar fascia, and the secondaries and inner primaries are still more broadly
edged on their outer margins with white. The tail is black, the three outer rectri-
ces white on their inner webs to within a short distance from '.heir tips, the
shafts white along the white portions of the feather. A white spot at the base
of the primaries (except on the first two or three,) is partially concealed by the
bastard quills. Below, with the feathers on the side of the lower mandible,
yellow.

The female has no black pileum, the crown being concolor with the back.
The yellow of the under parts is less pure and bright. The edgings of the
wings and coverts are grayish and narrow. The white on the inner webs of the
lateral rectrices is only indicated by a small, irregular, dull gray spot. The
spot at the base of the primaries is small and inconspicuous.

Young birds in August are above very dull and rather ochraceous olive, not
conspicuously different from the under parts. The edgings of the wings are
tinged with ochraceous. The basal primary spot is very small. There is uo
Judication of white on the rectrices.

Old males changing plumage during both the vernal and autumnal moult,
.-•have the olive of the back dull and obscured by dusky ; the pileum somewhat
variegated with olive. The wings and coverts have scarcely a trace of white
edging. The under parts are quite brightly yellow.

Why I have thus gone into detail in characterizing this species will be evi-
dent from the succeeding article. I wish it to be noted that the diagnostic
points of psaltria, as compared with mexicana, lie in the black pileum definitely
bounded on all sides with olive, not descending on the sides of the head below
the eye ; and in the decided olive of the upper parts. The bill is conical and
quite stout; the gonys straight; the culmen a little convex. The species ex-
tends over the western portion of the continent to the Pacific, and nearly, or
quite, to the Sonoran border.

Synonymy. Swainson's description* is very brief, unsatisfactory, and inac-
curate. Although the tail is not two inches long, (varying from 1-50 to 1"75,)
nor has its three lateral tail feathers (wholly) white, yet the diagnosis may be
accepted as indicative of the bird now well known from all portions of Mexico
as Chrysomitris mexicanus. Wagler's fuller description is quite pertinent. Upon
the latter author's authority, I quote Fringilla melanoxantha of Lichtenstein.
It is probable that Bonaparte's Chrysomitris nana belongs here. I have exam-
ined Mr. Giraud's type of Fringilla texensis. It has not a white belly as stated,
but is absolutely identical with typical Mexican examples.

The synonyms adduced under var. columbianus do not seem to require com-
ment.

Description. (Ad. tf, spring, S. I. No. 4078, Parras, Mex.) Bill a little
elongated, subclinical, culmen slightly convex, gonys a little concave; bluish
lead color. (Sometimes yellowish at base of upper mandible.) Black of up-
per parts quite pure and unmixed with olive, except on the rump, where a
little olive and more white may be seen on parting the leathers. The black
extends on the lores, auriculars, sides of the neck, and to a less extent on sides
of breast ; on the cheeks, between eve and lower mandible, somewhat mixed
with yellow. The under eyelid is yellow, separated from the yellow of the throat
by some black. The basal white spot on the primaries, (exclusive of the two
first,) and the white margins of the outer edges of the secondaries are well de-
fined, but the white tips of the median coverts, which form so conspicuous a
bar in psaltria, are much narrower. The three exterior tail feathers are almost
wholly white on their inner webs to within from a fourth to a third of an inch
of their tips. Below the bird is wholly yellow.

Numerous Mexican specimens hardly differ from the above, except in the
amount of white edging of the wings and coverts. This is so extremely va-
riable, that it cannot be a character of tbe slightest consequence. One (No.
4077, New Leon, Mex.) has some little olive mixed with the black of the back.

Another series of skins, five in number, from Panama, Co.-ta Rica, etc., with-
out exception differ from the Mexican type as follows : — The black on the side
ot the head descends much lower, in fact to the angle of the mouth, com-
pletely occupying the cheeks and auriculars, and the under eyelid shows no
trace of yellow. The under parts are of a much brighter yellow, rathtr
orange than lemon. Moreover, they average less white upon the wings and
tail. In some the white spaces only occupy two rectrices instead of three, only
extend to within half an inch of the tip, and are, in fact, rather small irregu-
lar blotches, than well defined large spaces.

A third series, also from Central America, presents precisely the features last
detailed, but the white on the tail feathers is either entirely wanting, as in No.
1818, or reduced to a minimum as in No. 39791. This form constitutes La-
fresnaye's C. columbianus.

NATURAL SCIENCES OF PHILADELPHIA. 88

Still a fourth series is recognizable in the collections before me, embracing
examples from New Mexico and Arizona; collected by myself near Fort Win-
gate, in New Mexico, and by J. H. Clarke on the Gila River. These exhibit a
remarkable gradation towards the peculiar features of psaltria. The black of
the back is mixed with about an equal amount of olive, the proportions of the
two colors varying from e. g. No. 37088, where there is only a trace of olive,
to e, g. Nos. 37091 — 2, where there is decidedly more olive than black, so
much indeed that this color forms quite a contrast with the black pileum. The
auriculars are black as in mexicanus, but, the yellow lower eyelid, like that of
psaltria, is not disconnected with the yellow of the throat. All three of these
birds i shot out of the same flock at the same time, (June 28, 1864.) The Gil*
birds agree exactly with the most olivaceous of these just described. A spe-
cimen No. 39094, tf, Aug. 18, Fort Whipple,) of supposed psaltria with a pure
olive back, has the auriculars black.

From the above detailed features of large series of skins, representing lo-
calities all the way from Panama to Northern Arizona, it will be evident that
the typical style of mcxicanus from the table lands merges, by insensible degrees,
through Costa Rican examples into an extreme of form which has been desig-
nated as C. columbianus. In like manner, just north of Mexico where the con-,
fines of the species inosculate with those of ■psaltria, we have a race or form-
showing decided gradations towards the characters of the Sa-t named species . .
But still the typical psaltria is so very diverse from mexkanus proper, and the
doubtful specimens incline po very decidedly towards the latter, that, in the
impossibility of uniting psaltria with mexieanus, we must consider them as " va--
rieties" of the latter, unless, indeed, they be hybrids between the two.*

Upon the whole, then, it may be best to refer all the black-backed examples.
to one species, — mexkanus, — recognizing three " varieties;" — columbianus, mex*
icanus and arizonsc, — as at least a convenient mode of indicating the differences,
whatever be their value, which actually do exist.

Regarding the females of the two species and of the varieties, \ confess my
inability to distinguish them with tiny degree of certainty, except by the lo-
calities whence they come, since all are quite similarly colored, and tut re are
no very tangible differences of form.

140. Chrysomitris Lawrencei (Cassin ) Bonap.

Abundant.; probably resident. My numerous examples of this species, so
widely dissimilar from any other, were all taken at Fort Whipple in winter.
Although I never noticed it at any other season, I have little doubt that it is a
permanent resident, breeding in the mountain* of Northern Arizona. I nave
seen summer examples from Fort Tejou, Cal. The differences between winter
and spring or summer specimens, consists in little else than the replacing of
theyellow dorsal spot by olive~gray, either pure or a little mixed with yellowish.
The yellow of the other parts is as bright as in spring, and the black frontlet
remains intact. Females want entirely the black on the head, which is all
around plain olive gray, while the pectoral spot and other yellow parts are dulli
in tint, and restricted in extent, or even, as may be the case sometimes with
the dorsal s<pot, entirely wanting. The iris of both sexes is dark brown. Iq
summer the bill and legs are fledi colored, more or less obscured bv
dusky; in winter the bill is hotn blue, and the legs, feet and claws blackish
liruwn.

The species has been hitherto considered as chiefly a California Coast bird.

If, as is probably the case, the Loxia mexicana of Strickland is rightly to be
referred to C. americana, then this species, being found breeding upon the Table
Lands of Mexico, and so general'y distributed throughout North America, must
be added to the Arizona list. It is doubtless to be found at times at Fort Whipple.

Chrysomitris trislis, Aegiolhus linarius, and, perhaps, Curvirostra leucoptera and
Pinicola canadensis, though not to my knowledge hitherto detected in Arizona,
will most probably be discovered in winter towards the northern boundary of
the Territory.

the characters presented by the bird in separating it from P. ornatus. It is
known to breed on the Table Lands of Mexico.

In crossing the Great Plains I found it abundant as far as the Raton Moun-
tains, westward of which I have never seen it. In the north its westward
range seems limited, but it extends al^ng the Mexican border, and across the
Southern Rocky Mountains and Valley of the Lower Colorado, and is found
also at Cape St. Lucas. It is not recorded from the coast region of Upper
California.

Many breed, and a few remain all winter. Extends southward to Mexico.

147. Passercdlcs alaudinus Bonap.

Abundant. Summer resident. My numerous specimens are referrible to
this supposed species, ditfering in some slight degree from the average of east-
ern birds in the grayish rather than decidedly yellow superciliary streak, and
the general paleness of the colors. The bill is perhaps a little slenderer and
more elongated. The differences which separate it from savanna appear to me
no greater than are to be found when large series of the latter are compared
with each other.

c<edingly numerous, they continued so until January ; after which only a few
stragglers were seen until the latter part of April, when they again became
common. By far the greater part go further north to breed. In general hab-
its this species seems to resemble albicollis rather than ;he more closely allied

Iris bright brown. Bill bright lemon yellow, dusky reddish at tip. Feet

is well known that occasional specimens are taken in the range of habitat
which belongs especially to Gambeli.

151. Junco hyemalis (L.) Sclater.

Rare and accidental. During the winter of 1864-65, I shot three typical ex-
amples of this species; in each instance iu company with both the succeeding
birds.

152. Jpnco oregonds (Towns.) Sclater.

Exceedingly abundant winter resident. Arrive at Fort Whipple about Oct.
10 ; soon become very numerous and continue so until the second week in
April ; stragglers seen till May * Keep quietly hidden in out of the way
places till cold weather has fairly set in, when they become very familiar, and
are to be seen everywhere.

Both sexes, and at all ages and seasons after the first autumnal moult, are
never without the reddish along the sides of the body ; and the head is never
entirely concolor with back.

Perfectly adult males have the head, neck all around, and breast pure black,
nearly as trenchantly defined against the reddish of the back as against the
white of the belly. The sides are strongly tinged with pinkish rufous. The
dull chestnut or reddish brown of the back extends on the scapulars and outer
edges of the secondaries and greater coverts. This color merges insensibly
into olive gray on the rump. The two outer tail feathers on each side are
pure white ; the third is white with an edging of dusky along its inner web to
near the tip. The bill is flesh colored, or delicate pinkish white; its apex
dusky. The tarsi are dusky flesh color, the feet more obscure.

The young female, early in winter, has the back more dully colored, while
the rufous tinge invades the nape and to some extent the crown ; and the edg-
ings of the wings and coverts are very light, being gray rather than rufous.
The black of the head and breast has a slaty tinge; and is sprinkled with light
grayish or rufous, which interrupts the deeper color, though never to the ex-
tent of making the parts concolor with the back. The wash along the sides is
fainter and duller. There is usually less white in the sides of the tail.

Between these two extremes is to be found every possible gradation. The
great majority of all males have the continuity of the black on the nape inter-
rupted by rufous tips to some of the feathers. A specimen (1138 of my collec-
tion, Dec. 12, 1864,) has a large abruptly denned pure white spot, of an irregu-
lar shape, on the chin. This is a curious example of partial albinism.

Numerous examples in my collection, agreeing with Woodhouse's types

Fort Whipple; times of arrival and departure, and general habits those of
oregonus, with which it associates freely.

The red of the back is a subtriangnlar patch of a bright ferrugineous tint
quite different from the chestnut of or eg onus ; its extent is smaller, and it is less
distinctly defined against the gray both of the nape and rump ; and does not at
any age or season invade the wing coverts. The outer edges of the secondaries
are grayish brown, even in full plumaged birds ; but the wing coverts are
purely cinereous gray like the rest of the body. The gray extends along the

sides of the breast and belly ; bat it is much lighter in tint than on the upper
parts ; and lias no very distinct line of demarcation with tbe white of the ab-
domen ; which latter varies greatly in parity and extent. There is never any
trace of reddish or pinkish on the sides; these parts being eoncolor with the
throat and breast, as in hyemalis. The space between the eye and bill, and to a
less extent the immediate circumocular feathers are blackish. The third lateral
tail featbtr has a greater amount of dusky than of white. Females are like
tli e males, except that tbe cinereous gray below is paler, the white abdomi-
nal region larger, and the union of these two colors more gradual.

I have tbtts gone somewhat into detail regarding the characters of oregonus
nnd eankeps, because in my collection are several examples which I regard as
most undoubtedly hybrids between the two. Their general aspect is that of
tanieeps ; ihe head, neck and throat being slate gray, not black ; the lores de-
cidedly blackish, etc. There is a large dorsal area, colored as in orego-
nus, and, most marked feature of all, the sides are strongly tinged with pink-
ish fulvous, exactly as in oregonus, instead of being plain cinereous gray, con-
color with the throat, as in caniceps. Other specimens preponderate still more
towards oregonus. in having the head and neck rather slate black than slate
gray.

The specimens are such palpable hybrids, that they need not in the least in-
validate the specific distinctions between the iwo species. In the case of Co-
Naples auralvs and mexicanus, it has been proven ineontrovertibly tbat such a
thing is entirely possible between closely allied though quite distinct species.

I have examined the type of Dr. Henry's Jwaco dorsalis, from Fort Thorn,
now in the Philadelphia Academy ; and I cannot discern wherein it differs
from tanieeps Woodh. This tatter species however seems quite distinct from the
Mexican cnterevs, in the restriction of the chestnut to a well defined dorsal
area, instead of its extending over roost of the wing coverts and tertials; and
in the wholly white outer tail feathers, whereas in einereus a portion of their
bases, especially on the inner web, are dusky. The range of habitat cf the
two species is also diverse.

154. Poospiza bilineata (Cass.) Sclater.

Rare at Whipple, where the nature of tbe locality is not suited to it. Very
abundant in the southern and western portions of the Territory. Open plains,
grassy or covered with sage brush.

In adult birds the black of ihe upper border of the superciliary streak ex-
tends across the forehead. Sometimes old birds have a decided ferrugineous
tint in the gray of the tipper parts ; but are never streaked. The moult con-
tinues until October.

The young bird differs materially from the adult. There is no black about
the head or throat, arid the white streaks are nearly obsolete. The superciliary
sireak is short and indistinct; ana is not bordered above by black. Thelores
are simply dusky and not pure black. The throat is pure white ; and has a
row of small spots oa each side forming an imperfect maxillary streak, dividing
the white of the throat from thai of the side of tbe lower jaw. The tipper parts
a>e strongly tinged with dull ferrugineous; and are obsoletely streaked in tbe
middle of the back with black. The wing coverts and tertials are strongly
edged with ferrugineous. The breast is white streaked thickly with dusky. The
tail is black as in the adult, and the outer feather is white on its external web ;
but the n< xt three rectrices are not tipped with white. The lower mandible
and the feet are dusky flesh color ; instead of both being, as in the ad alt, bluish
black.

355. Poospjza Belli (Cass.) Sclater.

Rather uncommon about Fort Whipple, for the same reason as mentioned
under head of P. bilineata. Abundant in the sage brush of the Gila Valley.
Keeps much oa the ground, where its motions are very like those of a Pipilo.

(156.) Spizella monticola (Gm.) Baird.

Rare and perhaps accidental. Colorado Chiquito River, Kennerly.

S57. Spizella socialis (Wils ) Bonap.

Very abundant summer resident. Arrives third week in March ; remains
until fatter part of November; a few stragglers may possibly winter. For a
month after its arrival it is in large flocks of fifty or more; and chiefly keeps
on the ground in open places, like Passercuhis or Pooecetes. In the fall, again,
•collects in large flocks, associating with Chrysomilres and Pipilones, and with S.
atrigularis. Mates in latter part of April. Remains in moult through greater
part of October.

Numerous specimens shot in the fall presented an aspect so different from
the usual well-known immature style of socialis, that I received the impres-
sion of a distinct species. The color of the crown was more the light ferru-
gineous of monticola, than deep chestnut, as in socialis. A large suite of adult
spring birds i cannot distinguish satisfactorily from the common eastern bird.

Spizella Breiceri, Cassin, Pr. A. N. S. Ph. viii. 1856, p. 40. Baird, Birds
N. A. 1858, p. 475.

Rare summer resident. A shy and retiring species, keeping mostly in thick
brush near the ground.

This species constantly presents perfectly tangible differences from pallida,
independent of the seasonal changes to which both are subject. In addition
to the general paleness, or, so to speak, obsoleteness of all the markings of the
body, the great differences in the colors and stripes of the head, as detailed
by Cassin and Baird, readily separate them. Breweri has no a«hy collar around
the back and sides of the neck, and the breast; but the small streaks of the
head and back are directly continuous. All the specimens before me measure
rather more in length than those of pallida, due ehiefly to a greater elongation
of the tail. Other measurements do not exceed those of pallida.

Some July specimens, in moult, present a faded and dull gray appearance,
with no signs of ochraceoin on any part; and all the streaks are so narrow
as to be merely faintly pencilled lines.

S. pallida is given by Dr. Kennerly from Bill Williams' River; and by Dr.
Heermann from Tucson and Pima, in southern Arizona. These citations are
doubtless to he referred to Breweri. Pallida is a species of the high central
plains and the region of the Missouri. Breweri ranges through New Mexico,
Arizona and California.

Rare. Summer resident. Arrives early in April, and mates shortly after-
wards ; remains till middle of October. In small flocks or rather companies,
in the fall associating with Chrysomitris and Spizella. In the spring has a
sweet and melodious song, far surpassing in power and melody that of all
other Spizellce. Young birds want entirely the distinctive facial markings
of the adults. Iris black. Bill dull red. Legs and feet brownish black.
Length 6-GO; extent 7'60; tail 3-10.

During my first autumn at Fort Whipple I shot numerous specimens of a Spi-
zella generally resembling S. atrigularis, but wanting entirely the black face
and chin. The interscapulars are of a quite different shade of chestnut. The

outer web of the external tail feather, and, to a less degree, the edge of the
inner web of the same, are quite purely white. The bill is dusky brown
above, dusky flesh color below, the feet black. The unusual length of the
tail also attracted my attention.

A fully adult male, procured April 20, has the black face and chin exactly
as in atrigularis. The interscapulars are of a brighter chestnut than in the
fall bird. The slate gray of the head and breast is deeper and purer, and
more markedly contrasted with the also purer white of the middle abdominal:
region.

An adult female in deep moult, procured July 21, has also no trace of black
about the head.

Several specimens from Cape St. Lucas, in precisely the plumage of my
autumnal Whipple examples, I find labelled by Baird with the MSS. name
" S. cana, n. s."

It is just possible that large series may hereafter establish a species from
Arizona and California distinct from the Mexican, both possessing the' black
on the face ; but at present I cannot satisfactorily distinguish two species.
Should they prove identical, they will afford an instance of a degree of sea-
sonal variation quite unusual in the species composing the genus Spizella.

The locality* whence were described the original specimens of " Zonotrichia
fallax" is so near Fort Whipple that, for all practical purposes, it may be-
considered the same. Such differences as exist are detailed by Prof. Baird,.
ut supra, with whose expressed opinion that the species is of doubtful
validity I entirely coincide.

M. fallax occurs throughout New Mexico, Arizona, and part of Southern.
California, and is particularly abundant in the Valley of the Colorado.
Westward of the Colorado Desert M. Heermanni chiefly replaces it. The lat-
ter species is very probably to be found at Fort Mojave.

(161.) Melospiza Lincolnii (Aud.) Baird.

This extensively distributed species, which occurs throughout the United"
States and Territories, and south into Central America, has been taken in the
Territory by Dr. Kennerly. I have not myself met with it.

The following Finches most probably remain to be hereafter added to the
list : Peiic.ira Cassini Baird, and Embernagra rtijirirguta Lawrence, in the-
valley of the Gila and Southern Arizona generally ; Passerculus sehistaceus
Baird, on the upper Colorado. (Specimens of the latter species are recorded
from Fort Tejon, Cala. )

162. Gcikaca cojrulea (Linn.) Swains.

Generally distributed ; nowhere very common. A single specimen taken
near Fort Whipple, Aug. 10, 1865. "Arrives at Fort Mojave May 1st."'
( Cooper.)

163. Guikaca melanocephala Swains.

Abundant. Summer resident. Arrives May 1st ; remains until latter part
of September. Frequents the thick brush of ravines, etc., and the cotton-
wood and willow copses of the creek bottoms. Its ordinary note intimately

*" Pueblo Creek, New Mexico," is now known as " Walnut" Creek, Arizona, anil is hardly a
day's march from Furl Whipple, which lies but a short distance off the trail of Lieut. Whipple's
party, in going from the San Francisco mountains to the Headwaters of Bill Williams' River.

resembles that of Lophortyx Garnbeli. Its song is superb ; a powerful but
melodious succession of clear rich rolling notes, reminding one somewhat of
the Icterus buLimore. " Net met with in the Colorado Valley." (Cooper).

164. Cyanospiza amcena (Say,) Baird.

Summer resident ; not abundant. More common somewhat further South.

PIPILO Vieillot.

The genus Pipilo of Vieillot, as now usually defined by ornithologists,
seems to embrace species not strictly congeneric with its type, P. erythroph-
thalmus. The differences lie chiefly in the shape of the wings and tail, and in
the relative proportions of these parts to each otber, as well as in the pattern
of coloration.

In the bird now generally known as Pipilo chlorurus these variations from
the type are most marked. The long wings almost equal the tail, which latter
is scarcely at all graduated. The elongated first primary gives a more
pointed shape to the wing. The pattern of coloration is unusual and quite
peculiar. The genus Kieneria was established by Bonaparte,* with the
Pyrgisoma Kieneri as type ; and under it this author ranges rvfipileus, fuscus,
Abertii, etc. But the P. Kieneri seems quite congeneric with the type of
Pyrgisoma; in which event Kieneria becomes a synonym, untenable for this
or any other group. " Pipilo " chlorurus being generically dissimilar from the
type of Embernagra (Saltator viridis Vieillot,) to which genus it has been
referred, very probably is wanting in a tenable generic application, unless the
name Chlorura f fills this vacancy.

After thus eliminating P. chlorurus, there still remain, in North America,
four species, crissalis X Vigors, mesoleucus § Baird. albigula Baird, and Abertii
Baird ; which agree with each other in differing from the black, white, and
chestnut group of which P. erythrophthalmus is the type, in the proportions of
wings and tail, amount of graduation of the latter, and pattern of coloration.
They should, I am of opinion, constitute a separate generic group, of which
P. Abertii may be considered the type. I believe that this genus has yet to
receive a distinctive name.

165. Pipilo megaloynx Baird.

Very abundant permanent resident. Rather more numerous in spring and
fall than at other times. Shy and retiring, inhabiting the thickest brush. Is
in moult through part of July, whole of August, and half of September.
Ordinary call-note almost exactly like that of Minus carolinensis : the song a
rather harsh and monotonous repetition of four or six syllables, something
like that of Euspiza americana. Females found with mature eggs in ovi-
ducts as early as May -5th.

The female of this species is not brown, conspicuously different from the
male, but only dull brownish black. I think this is the case also with the
other western Pipilos with spotted scapulars ; in which there is to be found
no such sexual difference as is seen in P. erythrophthalmus.

In carefully examining a very large series of Pipilo from Arizona, as well
as from other localities, I find it difficult to discern constant and tangible dif-
ferences between arcticus and megalonyx. My specimens are all referrible to
the latter species, or variety, if it be only one. I prefer now to leave the sub-

ject as Prof. Baird has determined it ; especially as iu his forthcoming
"Review " the matter will be re-examined.

(166.) " Pipilo " Abertii Baird.

One of the most abundant and characteristic birds of the Valley of the
Gila and Colorado. Ranges northward to within a few miles of Whipple, bnt
is not found in the adjacent mountains. Common at Fort Mojave, and par-
ticularly so at Fort Yuma.

(167.) "Pipilo" ME=iOLEcrctJS Baird.

Abundantly distributed throughout the warmer portions of New Mexico
and Arizona, from the Valley of the Rio Grande to that of the Colorado. Not
observed at Fort Whipple, though found breeding some twenty-five miles to
the southward. Associates freely with the preceding, and inhabits the same
regions ; and the two have very similar habits.

This species is permanently and very distinct from crissalis, Vigors, of the
California Coast, or from albigula of Cape St. Lucas ; which species it replaces
in the southern Rocky Mountain region.

168. " Pipilo " chlorura (Towns.)

Spring and autumn migrant ; none breed or remain all winter. Pa=ses
rapidly by Fort Whipple ; being found only during the latter part of April
and beginning of May, and during the month of September. The most silent
and retiring of the " Pipilos " being very difficult to observe or capture.
"Winters sparingly at Fort Mojave," {Cooper).

The species varies a good deal in the color of the iris ; e. g., No. 738, iris
dark red ; No. 739, iris olive brown ; No. 740, iris reddish brown ; all of
which birds were shot at the same time.

(169.) Pyrrhdloxia sinuata Bonap.

This Mexican species, introduced into the United States Fauna from the
lower Rio Grande Valley, has been taken at Fort Yuma. It is now well
known as a common bird of Cape St. Lucas.

The Cardinalis igneus, Baird, (Pr. A. N. S. Ph., Nov., 1S59, p. 10,) very
abundant at Cape St. Lucas, may also very probably be found in the south-
western portions of the Territory.

JCTERID.E.

170. Molotitrits pecoris (Gm.) Swains.

Very abundant summer resident ; arrives middle of April and remains
until October. Vast numbers seen at Fort Yuma in September. Winters
abundantly in the Colorado Valley.

171. Agel^eus phceniceus (Linn.) Vieill.

Common ; resident. Most numerous in October and November. Associates
constantly and intimately with the succeeding spfcies.

A. gubernator is given by Dr. Kennerly from Pueblo Creek, Ariz. He very
probably made an erroneous identification. It is doubtful if either gubernator
or tricolor, so abundant in California, ever cross the desert to the Colorado
Valley, except in isolated and accidental instances.

172. Scolecophagus cyanocephalus (Wagl.) Cab.

Exceedingly abundant ; permanent resident. The typical Blackbird of
Fort Whipple. Comparatively few breed in the immediate vicinity. Towards
the end of September they become very numerous, and continue so until
May, when few are to be observed until the following fall. Congregate in
immense flocks about the clearings, stock corrals, etc., and are tame and
familiar. By no means a uiarsk species, but rather a pini'oline one. Their
note is a harsh rasping or grating squeak, varied at intervals by a rather
melodious ringing whistle.

[March,

NATURAL SCIENCES OP PHILADELPHIA. 91

Male; average 10-00x16-50: iris light creamy yellow. Female; average
9-00x15 '25 ; iris brown. Autumnal males are frequently seen in nearly
complete plumage.

173. Xanthocephalus icterocephalus (Bon.) Baird.

Rather uncommon, being less numerous than at most other localities where
found at all. Chiefly a summer resident. Rather a marsh and prairie spe-
cies, than a bird of mountainous regions.

The variations in the tint, and in the extent or restriction of the yellow, de-
pendent upon age, sex or season, as well as purely accidental, are very great, and
almost interminable. Some immature males have the head saffron or ochra-
ceous, the nape clouded with black, and a distinct median longitudinal black
stripe along the crown. Sometimes very young males show no yellow what-
ever. The size is also liable to great variation ; a female before me being
hardly half the size of an adult male. (Wing 4-25 instead of 550 ; tail 3-25
instead of 4-10, etc.)

174. Sturnella neglecta Audubon.

Rare ; resident. The nature of most of the vicinity of Fort Whipple is not
well adapted to the habits of this species. I never saw a half dozen individu-
als during my whole stay.

175. Icterus Bcllockii (Sw.) Bon.

Common summer resident. Almost exclusively frequents the willows and
cottonwoods of the creek bottoms, to the small twigs of which its pensile nest
is attached. Arrives late in April, and remains through greater part of
September.

The female is plain grayish olive (pure gray on the rump,) brightening into
olive yellow on the nape, upper tail coverts and tail. Forehead, superciliary
streak, sides of head and neck, and a large space on the breast bright yellow.
Space between eye and bill and the whole chin pure white. Rest of under
parts grayish white, tinged with yellow on the under tail coverts. Median
wing coverts broadly edged and tipped with white. Bill and feet similarly
colored with those of the male.

CORVlDsE.

Corvus cacalotl, Wagler. Isis. 1831, 527. (Mexico.) Baird, B. N. A.

1858, p. 563. (Colorado Valley.)
Corvus carnivorus, Bartram ; Baird. B. N. A. 1858, p. 560.
Resident. Very abundant, especially about the clearings, cattle enclosures,
etc., where it congregates in immense numbers in the autumn and winter.
During the severe winter of 1864-5 great numbers perished at Fort Whipple
by cold and hunger.

I cannot distinguish the Colorado Raven even as a well-marked variety of
carnivorus. Specimens from all points between the Arkansaw river and the
Colorado desert seem to me quite identical.

177. Picicorvus Coldmbianus (Wils.) Bon.

Abundant at irregular intervals during the winter months ; from the middle
of October till March. High open forests. Restless, shy and noisy.

Iris brown ; bill and feet black; hard parts of mouth livid, fauces pinkish.
Specimens in moult have the plumbeous intercalated with a hoary, almost
ochraceous whitish, produced by the fading of the original colors. Individu-
als vary much in size.

178. Gymnokitta cyanocephala Maxim.

This singular and interesting species has the form of a crow ; but its colors
and its habits are most decidedly garruline. It is a very abundant and
characteristic bird at Fort Whipple, remaining all the year. It breeds in the

PROCEEDINGS OF THE ACADEMY OF

retired portions of the neighboring mountains, the young leaving the nest
early in July. During the winter months they collect in immense flocks ;
sometimes, as I witnessed in at least one instance, to the extent of a thousand
or more. These large companies scour the country about, flying restlessly
and noisily from place to place, and generally scattering over a considerable
area. They are shy and wary, so that, notwithstanding their numbers, they
are difficult to shoot. Their food is chiefly seeds, berries and nuts, especially
the nuts of the Pinus edulis, and the berries of Juniperus pachydermia. They
alight much on the ground, where their gait is firm, erect and easy. Their
flesh is quite palatable.

Iris brown. Bill and feet black; soft parts of mouth rose red; corneous
parts black. Males range from 11-50 to 12.00 in length, by from 16-50 to
19-00 in extent ; the females from 11-00 to 11-50 in length, by 1625 to 18-00
in extent. Differences in length are by no means always accompanied by
corresponding discrepancies in extent of wings. The intensity of the blue is
liable to great variation, as is also the distinctness of the white gular streaks.
The blue of the head usually merges quite insensibly into the grayish blue of
the back ; but there is often quite a distinct line of demarcation. Specimens
in poor plumage have frequently light gray primaries.

179. Cyanocitta Woodhousei (Baird.)

Cyanocorax californica, Woodhouse, in Sitgreave's Rep. Expl. Col.

and Zufii R. 1853, p. 77. (San Francisco Mts.)
Cyanocitta Woodhousei, Baird. B. N. A., 1858, p. 5S5.

Resident, and exceedingly abundant, being the most characteristic species.
Found in all situations ; but rather shuns dense pine woods and keeps on the
open hill-sides, among the scrub oaks. etc. In winter collects in rather large
flocks, sometimes as many as fifty ; usually, however, seen in little companies
of half a dozen individuals. A restless, vigilant, shy, and noisy species.

Males average 12-00x16-50; females about 11-25x15-50. In moult, ex-
amples are often seen with gray like that of the dorsal patch intercalated with
the blue of the head. Iris brown ; bill and feet black. Mouth dull bluish
white.

I think there is no doubt of the propriety of separating the southern Rocky
Mountain Cyanocitta from the true californica of the Pacific coast. The
characters as detailed by Baird, ut supra, are very constant and quite
appreciable.

It is very probable that C. californica and C. Woodhousei will be found
associated at certain portions of the Colorado desert, as for example along the
Mojave river.

(180.) Cyanocitta sordida (Sw.) Baird.

Chiefly a Mexican species, but extending northward to the Gila Valley.
Fort Buchanan, Dr. B. J. D. Irwin, U. S. A. Copper mines, J. H. Clark.

181. Cyanura macrolopha Baird.

Common ; resident. Almost exclusively pinicoline. Generally found in
small companies : never congregating to the extent even which C. Woodhousei
does. Very shy, vigilant, noisy and tyrannical.

A very young bird taken July 22, on the San Francisco mountains, besides
being smaller, and having a weaker bill and feet, differs considerably from the
adult in colors. The upper parts are rather smoky brown than blue ; and
this color also invades the rump. Below the colors are also fuliginous ; only
a slight leaden or grayish cast indicating the future bright blue. At the same
time the wings and tail are nearly as bright blue as in the adult ; but the
black bars upon them are very obsolete, or wanting altogether. There is
considerable of a crest, but its color is fuliginous black instead of deep glossy
black ; and there are no traces of the white front and white about the eyes.
The crest is about as long as that of an adult Stelleri.

[March,

NATURAL SCIENCES OF PHILADELPHIA. 93

The differences between this species and Stelleri of the Pacific coast, as de-
tailed by Prof. Baird, seem to me quite sufficient to separate them. I may
add, that in macrolopha the bluish white wash on the front occupies,
when the feathers are undistorted, two straight lines, ascending perpendicu-
larly from each nostril, and quite distinct from each other ; while in Stelleri
the tendency is for the whole front to be indiscriminately washed with bluish.
In both species, the colored tips of the frontal feathers have a somewhat dif-
ferent texture and consistence from their dark basal portions.

A large series of specimens, chiefly from the head waters of the Columbia*
have the front washed with dull blue just as in Stelleri; and have also the
white supra-ocular spot of macrolopha. It is quite possible that hybrids of the
two species may occur ; but I am not prepared to say positively that such is
the case in the present instance. Both species are found in the regions above
referred to.

(182.) Pica hudsonica (Forst.) Bon.

Spariugly distributed throughout the Territory. Not personally met with
at Whipple.

Young birds shot in June in the Raton Mountains near Taos, N. M., have
the bill tipped with yellowish. The tail is only about three inches long. But
there is a most remarkable similarity in color to the adults ; almost the only
perceptible differences being a restriction of the white on the primaries, and
rather dull greenish black instead of violet black wings and tail.

The yellow billed P. Nuttallii, so abundant in Southern California, does not
appear to cross the Colorado desert to the river.

COLUMBWsE.

183. Columba fasciata Say.

Summer resident ; very rare ; observed only on two occasions.

184. Melopeleia leucoptera (Linn.) Bonap.

Rare ; summer resident. Young birds, half fledged, taken Aug. 15, 1864.

185. Zenaidura cakolinensis, (Linn.) Bonap.

Abundant summer resident. Arrives last week in April, remains until
middle of October. "Winters at Fort Mojave, and on the Pacific coast as
high as San Fraucisco." (Cooper.)

To the traveller on the dry sandy wastes of Arizona this bird is always a
welcome sight, indicating with certainty the presence of water in the vicinity.
I have never known the sign to fail in my own limited experience. The na-
ture of the food ordinarily taken necessitates an abundant supply of water.
This was satisfactorily demonstrated to me on one occasion, when the crops of
several, shot just as they were coming to drink, were filled with small seeds,
as dry and hard as when first ingested, and totally unassimilable until mace-
rated with water.

186. Cham^epeleia passerina (Linn.) Swains.

A rare and probably accidental visitor to the Valley of the Colorado. (Fort
Yuma, lees, La Paz, Hut.ton. ) Probably goes at least as high as Fort Mojave.
Perhaps variety pallescens Baird, from Cape St. Lucas.

PHASIANIDsE.

187. Meleagris mexicana Gould.

There can be no doubt of the propriety of separating the Western Turkey
from the common species of the Eastern United States. The differences are
very decided, and of such a character as to have an important bearing upon
the question of the origin of the domesticated bird. The latter, as is well
known, usually approaches mexicana rather than gallipavo, in its colors.

The wild Turkey is a permanent resident of the mountains of the immedi-
ate vicinity of Whipple, but quite rare, so much so that I procured no speci-
mens. In some portions of the Southern Rocky Mountain region it is exceed-
ingly numerous.

I have never detected any of the Tetraonidce in Arizona, though very pro-
bably the Centrocercus urophasianus may be hereafter found towards the Utah
border. Dr. Cooper has seen it on the Mojave River, about the southernmost
point it has yet been observed.

Among the Lagopidce, the Lagopus leucurus has been detected as far south
as Cantonment Burgwyn, in New Mexico, (lat. 37°,) and most probably will
be found in the mountains near the northern border of the Territory.

The common and characteristic Quail of the Southern Rocky Mountain re-

the L. californica. The two species have been found associated at Soda Lake,
the sink of the Mojave River.

In my paper, as above, will be found some account of the habits of this
Quail, which I had previously, in the same Journal, (Ibis, 1865, p. 165,)
incidentally mentioned erroneously as L. " calif 'ornicus." From a large
suite of specimens, lean describe the following stages from the callow state to
the fully adult condition.

Downy state, a few days old. — Bill bright reddish above, nearly white be-
neath ; feet dull flesh color. Head yellowish white tinged with grayish brown ;
the occiput with a broad spot of pure brown ; on the centre of the crown
I whence the plume will spring) a few black feathers, each longitudinally
streaked with white. Entire upper parts brownish gray, (color of the lighter
parts of the back of a Sturnella,) mottled with spots of black, and very con-
spicuously streaked with long, sharply pencilled lines of white. Primaries
dusky, their outer vanes marbled with brownish black and grayish white.
Whole under parts from the white jugulum narrowly and semiconfluently
barred with black and ochraceous white, and longitudinally streaked with
short but distinct lines of pure white. This coloration is most marked and
definite on the breast ; on the flanks and under tail coverts the markings are
duller and moie blended. The newly sprouted tail feathers are colored like
the primaries. Length about 3| ; wing 1| ; tail J. This stage may be seen
up to the last of August.

Quarter grown. (Aug., Sep.: length 6 or 7 inches.) The general hue is
dull leaden gray, becoming ochraceous on the scapulars and wing coverts,
which are still a little mottled, as described above. Below the gray is very
light indeed, almost wliitish, especially on the chin and middle of the belly.
Breast obsoletely waved with light and dark shades of gray, with s'ill some
slight traces of the white longitudinal lines ; the crissal and anal regions the
same, but somewhat tinged with brown. On the sides under the wings there
is a slight fulvous or ferrugineous tinge, but nothing like definite strips. Pri-
maries plain dusky ; tail more plumbeous ; very finely marbled with blackish
and whitish. There is a broad superciliary white stripe extending to the ex-
treme occiput.

During first autumnal moult. (Sep., Oct., Nov.) The preceding two plu-
mages are those of chicks, with few true feathers. When the autumnal moult
has made some little progress, the features of the adults begin to appear,
mixed in a varying degree with the preceding downy colors. Some of the

[March

NATURAL SCIENCES OF PHILADELPHIA. 95

wing coverts and secondaries are still mottled, and the tail is a littled marbled,
but "most of the feathers are clear plumbeous. On the breast, feathers of this
latter color are interspersed with the wavy gray ones. While the faint ferru-
gineoas flush of the sides is retained, there are apparent the definite stripes
of the adult. The crest is now an inch long, but still straight, not recurved,
and rather brown than black. The bill is quite black, and the feet dark
colored. At this season the peculiar head markings begin to appear, so that
the sexual features are quite apparent.

The early age at which the crest begins to be apparent is surprising. Two
or three feathers longer than the rest very plainly indicate it in chicks only a
week or two old. But it does not become black and expanded and recurved
at the tip, till the bird is full grown and has completed the moult.

Adult. Iris clear brown. Bill black. Legs and feet brown, sometimes
with a livid bluish tinge.

(189.) Callipepla squamata (Vig.) Gray.

From the Valley of the Gila and Lower Colorado, as well as that of the Rio
Grande. Not detected as far north as Whipple.

190. Cyrtonyx massena (Less.) Gould.

I had frequently been informed of the occurrence of this species at Fort
Whipple, but I never met with it on but two occasions, when an adult male
and female were procured. It is doubtless a resident, though rare species.

No. 1586. $. Oct. 11, 1865. Length 9-00; extent 17 00; wing 4-80;
tail 2-00; bill -60; tarsus 1-20. Upper mandible dull reddish horn; lower
bluish white. Mouth whitish flesh color. Legs, feet and claws livid white,
with a somewhat yellowish tinge posteriorly. Iris brownish olive. The cut-
edges of the lower mandible are doubly dentated near their end.

Whipple series, but only those actually seen by me in that locality are given

ARDEID^E.

Very abundant throughout the Valley of the Colorado.

(193.) Herodias egretta (Gm.) Gray.

Abundant along the Colorado. Very probably tbe large variety californica
(Baird B. N. A. p. 667,) may also be found within the limits of the Territory.

(194.) Ardea herodias Linn.

Exceedingly abundant along the Colorado River. The nests of this species
are often seen on some ledge of rock projecting from the precipitous cliffs
which are covered with innumerable nests of Petrochelidon lunifrons.

Sparsely distributed throughout New Mexico and Arizona. I have seen it

CHARADRIID^E.

201. Aegialitis vociferus (L.) Cass.

The only small wader found in any considerable numbers about Fort
Whipple Summer resident, arriving early in April and remaining until
November.

(202.) Aegialitis semipalmatus, (Bp.) Cab.

Colorado River, September and October, 1865.

The Charadrius virginicus, and the Sguatarola helvetica are both doubt-
less to be found in the Territory, though I have never seen specimens from
within its limits.

PODASOCYS* Coues, nov. gen.

Gh. Gen. Bill two thirds as long as the skull; equal to the middle toe and
claw; but little more than half the tarsus. Wing of moderate length, reach-
ing when folded beyond the taiit ; second primary nearly as long as the fit st.
Tail exceedingly short, contained twice in the length of the wing from the
carpus; square; the rectrices broad to their obtusely rounded tips. Legs
stout and very long; denuded portion of tibia two-thirds as long as the tarsus,
the latter nearly twice as long as the middle toe and claw; tibia and tarsus
entirely covered with small, polygonal, reticulated plates, largest on the ante-
rior face of the tarsus. Tjes very short and stout ; lateral ones unequal in
length : tip of inner claw nearly reaching base of outer lateral one ; tip of the
latter falling short of the base of the middle one. Claws short, obtuse and
little curved. Of moderate size, compact form and dull colors.

Type. Charadrius montanus Towns.

In general form this genus approaches somewhat JEjialitis, especially that
section of which melodus is typical (yEgialeus). But it differs widely in the
very short squire tail, long denuded tibia;, very long tarsi, much abbreviated
toes, etc. It is possible that some genus already founded upon an exotic type
may include montanus, but knowing of none such, I have no other alternative
than to institute a new name, in separating a heterogeneous element from the
genus with which it is usually associated.

203. Podasocys montanus (Towns.)

This species has an extensive range quite from the northern boundary of the
United^States to the Mexican border, and perhaps much farther each way ;
though at the same time it is strictly confined to the western portions of the
continent. It is sparingly distributed throughout Arizona. I have constantly
met with it from the Rio Grande to the Pacific, in all the regions suitable to
its pecultar habits. I believe it is quite confined to dry plains either entirely
bare or covered with straggly brush. In its habits it differs as much from
most other Charadriinx as does its form ; calling irresistibly to mind the
Eremophila cornuta. The stomachs of the specimens examined contained or-
thopterous and coleopterous insects.

Actodromas Bairdii, Coues, Pr. A. N. S. Ph. 1861, p. 194.
Very generally distributed throughout the whole interior of North America.
No instances of its occurrence on either the Atlantic or Pacific coasts have
come to my knowledge. Examination of several specimens taken near tha
Pueblo of Zufii, in New Mexico, by Dr. S. W. Woodhouse, which were not ac-
cessible at the time of the preparation of my monograph, as above, shows them
to belong to this species, and not to the A. Bonapartei, with which Dr. Wood-
house had identified them under the erroneous name of Tringa Sckinzii. These
specimens are interesting, as extending the range of ihe species west of the-
Rocky Mountains, and causing it to be included in the Whipple avifauna.

This species has been recently referred to A. maculata, and considered as
founded upon a smaller race or upon immature specimens of the latter species,
by Dr. H. Schlegel ;f certainly an unfortunate error, and one well illustrating
how unsafe it is to pass judgment upon a species with which we are autopi-
cally unacquainted. If there be any specimens in the Museum of the Pays-
Bas referrible to maculata in any of its variations of size or colors, they are
by no means examples of the species I have named Bairdii.

(210.) Actodromas minutilla (Vieill.) Coues.

Seen in flocks on Little and Great Colorado Rivers, from July to October.

(211.) Ereunetes pusillus (Linn.) Cass.

Common on the Colorado. It is quite possible that Mr. Lawrence's new,
E. occidentalis may also be found on the streams of the Territory.

Sparsely distributed throughout the Territory. Individuals seen Oct. 18th
1864, in a marsh near Whipple.

It is a question with me whether this species should retain the name above

Lath. The bill is not red at all, but yellow ; and it is the P.fuscus whose bill
really is red. The name thus conveys such an erroneous impression, as should
justify its rejection.

The P.fuscus is essentially a maritime bird, and if found upon the Colorado
at all, is probably only a straggler.

Much material additional to that possessed by Mr. Lawrence in 1858, or by

The original P. californicus, as characterized by Dr. Heermann, is based upon

It was shown in the Proceedings of the Philadelphia Academy for 1862 that
the bird is neither more or less than the young of the American auritus; full
j'lumaged specimens of which I easily distinguished from tbe European auritus.
The name californicus I adopted as obviating the necessity of a new one, al-
though Dr. Heermann's diagnosis gives none of the special points which sepa-
rate the bird from auritus ; but shall claim the species for my own, from the
very different interpretation of it which I have elucidated.

A letter was read from Dr. Gr. Lincecnm, of Texas; containing a
history of the "small black erratic ant," as follows :

The small black, crooked running ant, socommon in everybody's yard, and
on almost every growing twig in spring time and summer, is called, in my
catalogue of ant species, the erratic, or crazy ant. He is No. 5 in my notes
on the various types of ants. In this species, the formic acid odor is very
strong when the ant is crushed. He is quick in his movements, does not
make paths, but travels in scattered files, in the same direction, sometimes
several hundred yards; moves quickly on a general course, running very
crooked the whole route, giving his path a broad range, travelling two or
three times the distance to his place of destination. All along the range of
their path, at unequal distances, are depots or station-houses, at which they
often call as they pass along, giving the whole affair quite a business aspect.
Or it may be that what I have denominated depots or station-houses, will turn
out, on a more careful investigation, to be a line of regularly constituted and
well organized confederate cities, among which there is carried on a rapid
and extensive commerce. At any rate, there can be no doubt of the fact that
they are engaged in an extensive and well-established, reciprocal intercourse
throughout the entire line of their cities. Cripple one of them on the route
of his travel, and you produce the wildest excitement, and the invalid will be
visited and examined by perhaps 500 of the travelling throng in the course
of two or three minutes. If the case is a curable one they work with him
until he is on foot again, when he moves onward with the crowd as before.
If he dies, they remove him from the range of the great thoroughfare, and
business rolls on again.

They sometimes wage war with the red-headed tree- ant, (he is the No. 4
of my catalogue, and may be fully described in some future article), and the
conflict is generally quite disastrous. Notwithstanding the fact that they are
always able to bring to the field more than ten times the number of their red-
headed foe, they often meet with defeat.

I was spectator to a battle, or rather a field fight, between these two species
of ant, that continued four or five hours. Small parties were engaged in the
deathly conflict at sunrise, when I first observed them. They were fighting
in the wagon road, and their numbers were rapidly increasing. At the time
I was called to breakfast, they were in considerable force on both sides, and
when I returned I found both armies greatly augmented. Reinforcements
were constantly arriving, and the battle was raging over an area of eight to
ten feet in diameter. The discipline and modes of battle of the two species
are entirely different. The method of attack, by the little black ant, is aimed
altogether at the feet and legs of the foe ; and as they greatly outnumber the
red heads, by engaging them two or three to one, they succeed in maiming
and rendering large numbers of them unfit for service. The red heads seem

to aim only at decapitation, and this they accomplish with dexterity and sur-
prising facility. Reinforcements were momentarily arriving to both armies.
Thousands were already engaged, and the bloody strife was raging over the
entire area of the battle-field.

Being controlled only by two forces, — desperation and death — the scene
was terrific beyond my powers of description. In all directions, everywhere,
were seen the dire effects of relentless war. The battle-field was already
thickly strewn with the dead and dying, over whom, in regardless tramp,
swept the furious antagonism. Here indeed was, for once, at least, full mani-
festations of the unmistakable, genuine " tug of war." Violently struggling
and gnashing their jaws ; clinging together and wallowing on the ground, in
companies, in squads and single combat, the direful contest fiercely raged.
Dispatches had been sent off by the black ants for their entire reserve to be
forwarded immediately, and they were pouring out by the million from the
gates of their great city, — distant about 60 feet, — and hurrying toward the
battle-field. They were evidently making a forced march, and their numbers
were so great, that by the time they had progressed 20 to 30 feet, their line
of march suggested the idea of a broad black ribband trailing on the ground,
mid there seemed to be no end to them, for they were still flowing out from
the city in countless thousands.

At this crisis their army on the battle-field gave way and was routed, and
in a general panic commenced a retreat. Soon, in their disorderly flight, they
met their reinforcements and communicating to the front ranks their total and
disastrous discomfiture, the panic became universal, and reinforcements and
all fled precipitately into the city. In five minutes there were no black ants
to be seen above ground. The news of the great battle and its disastrous
results seemed to have been spread around to those even who had not been
engaged in the battle, but who were busied in their daily avocations. At all
events, from some cause the black ants immediately disappeared entirely from
the top of the earth in that vicinity. Not so on the battle-ground. The vic-
tors occupied the ensanguined field, and were busily employed for several
hours. Many of them were attending to the wounded, which were numerous,
and whom they carried into the shade of a large clod of earth, that had been
turned up by some heavy road wagon, to get them out of the scorching sun-
shine, which was pouring down in great force, it being now nearly 11 o'clock.
Much the larger portion of them were gathering up and packing off the de-
capitated bodies of the black ants, and carrying them up a post oak tree, in
which they had their city, and which also stood near by. Upon these head-
less victims of the bloody strife they intended, as I supposed, to have a grand
feast.

There was a great running to and fro by those who were attending the
wounded. They seemed to exert themselves greatly and to manifest much
sympathy for them. In the course of an hour many of the wounded were so
far recovered as to be able to travel, while those who remained invalid were
carried up the tree by their friends. Although great numbers of the red-heads
were wounded, and some of them seriously, there were but few dead ones,
and these were carried up the tree with the headless trunks of the conquered
foe. After the victorious red-heads had left the battle-field, the only signs
that remained to mark the place of the destructive contest was the dissevered
heads of the vanquished. Of these there were so many that they suggested
the idea of gunpowder strewed along the ground.

The food of this species of insect is various. He is quite fond of vege-
table oils, sweet saps and honey. He collects his sweets from the tender
buds and glands and blooms of plants, and in great quantities from the aphis
— vine fretter or plant louse. These plant lice have their inflected beak in-
serted in the tender bark of the buds and twigs of the growing plants, vines
and the like, where, in dense crowds they cling, sucking the sweet sap.
Among these masses of plant lice is ever found great numbers of the erratic

auts, carefully and gently walking through the ranks of the sap-sucking pests ;
busily engaged in licking up the honey dew, which is nothing more than the
transparent excrementitious fluid, that is momentarily dropping from the
countless aphides. To facilitate the process of collecting these precious
sweet drops, the ant caressingly applies its antennae to the bloated sides of
tae plant louse, who obligingly turns up his tail and delivers the sweet little
transparent drop, which is thankfully received and licked up by the polite
little teaser. From observations on this peculiarity in the character of the
erratic ant, have originated the occasional accounts we have seen published
in the newspapers about the ant's milk cows. As far as my observation goes,
the erratic ant is the only one of the genus that visits and collects the excre-
mentitious droppings of the aphis.

Besides the great quantities of food collected from the aphis, or plant lice,
by these courageous and extremely industrious little creatures, the oakfamily
of trees affords them large supplies. The post oak {Quercua obtusiloba) and
the black-jack (Quercus nigra) particularly. They will travel a long distance
from home to visit a thrifty-growing tree of either of these oaks. And. as
these trees yield their supplies all the time of the green foliage, they generally
establish a chain of depots along the line of travel, from their nearest city to
the food-giving tree. Or it may be, that finding the selected tree capable of
supplying food for great numbers, they have, instead of depots, extended
their cities along the range of the great thoroughfare, and thus, by the addition
of city after city, strengthen the confederacy, and increase the faciliities for
procuring provisions for their great and extended realm.

This is no fiction, or fancy sketch, in the history of the contrivances of these
thoughtful little emmets. It is sometimes a hundred yards or more from the
mother hive, or city, to the tree that their commissaries have selected ; and at
various distances along the road, they do erect new establishments, at first,
thinly scattered on the route, which are, however, seen to increase annually
all the way to the tree, if it remains alive, — and these are either depots,
places of deposit for their surplus accumulations of their stores of provisions,
or they are confederated communities. Be it either way, the fact that they
are carrying on a well-regulated and thoroughly-understood system of
friendly, reciprocal intercourse cannot be denied ; that is, as far as any one
line of depots, or cities, as I prefer to call them, are concerned.

Coming across any one of their great thoroughfares we find them streaming
along in both directions. Take either end of this road, and you may trace
it to its terminus. It may be some distance, but you will find it if you per-
severe, either in a terminal city, or a live tree ; and that it is not connected
with any other range of cities, (I prefer the term cities), which, as I think,
further and more careful investigation will decide these peculiar ranges of
ant nests to be.

In large towns and cities constructed by the human species, where they
have cut down and destroyed the forests, these sagacious little ants would have
to evacuate such places, if they possessed no reasoning powers to enable
them to adapt themselves to other conditions and circumstances. The ant
finds that the march of civilization has crushed out and destroyed all his
resources for subsistence ; and viewing arrogant man as the prime cause
of this great loss, he quickly decides to hold him accountable, and force him
to make good the damage. To effectuate this grand retaliative resolve, he forth-
with transports his eggs and young ones, with their nurses and teachers into
the intruder's kitchen, into the little crannies arid cracks, in the timbers about
the dairy and dining apartment, and particularly beneath the hearths in the
dwelling. In these newly-established homes they become more thrifty than
they were while in a natural state. Finding provisions abundant and very
convenient, they are encouraged to labor more, and they increase at a ratio
unprecedented. Soon their numbers are so great that they are to be seen in

1866.]

104 PROCEEDINGS OF THE ACADEMY OP

all portions of the house, sucking and carrying away every thing greasy or
sweet that is not hermetically sealed. They cut and destroy window curtains
and articles of clothing that are starched.

One way to destroy the erratic ant, is to lay out a greasy rag or recently
laid aside greasy bone. By either of these experiments multitudes of them
will be attracted, and when sufficient numbers of them have collected on the
bait, hold it in the flame of burning shavings or other quick combustible,
repeating the experiment frequently. But if the bone or rag be left undis-
turbed, it will not be long until they have extracted every particle of the oil
from it ; and should there be any scraps of flesh remaining on the bone
when it is cast aside, it will be found that in a short time, they have cut
the flesh to pieces, and after extracting the oil it may have contained, dropped
it down in the form of dry powder, showing conclusively that they do not
subsist on flesh, or dry food. They treat the kernels of any of the oily nuts
in the same way Hence I conclude that they subsist on a fluid diet, and
that they, like the honey bee, are provided with an internal sack, or pouch,
in which to transport their stores to the cities.

This day, 22d August, I observed the erratic ant in great numbers, carrying
something in their mouths, and, as it was a visible something they were
packing home, I was curious to know what it. might be. So I robbed a couple
of them of their freight, which, on being exposed under the microscope,
turned out to be the carcass of the smallest — almost microscopic — black ant,
the No. 7 of my catalogue. After making this discovery, I examined quite
a number of them, and found the abdomen of all alike torn open and emptied
— disembowelled. They were bringing them from beneath the cook house,
where the poor little fellows had been filling themselves with was'e syrup
that had been spilled there. This circumstance had been discovered by some
of the spies of the erratic ants, and now, as it had been licked np by the little
ants, there was no way left for them to possess themselves of ihe rich treasure
but to wage war upon the smaller ant, and tear it out of their full sack. And
this ihey had already accomplished before I discovered them, and were now
carrying home their lacerated carcasses, to have them sucked and dried of
their blood and other contained fluids.

This type of ants is very numerous, courageous, and exceedingly thrifty
and belligerent. He will engage in battle with any of the other types. They
occasionally succeed in capturing the large, red, agricultural ant. (Myrmka
molefaciens, S. B. Buckley.) I did not know then how they had managed to
take him ; but they had one of these big red fellows very secure when I first
discovered them, and were making a great parade around him. They were
clinging two or three to every leg of the large ant, and great numbers were
parading and ranting on each side of the road, as they slowly and laboriously
moved along with their giant captive, who seemed to be not only in great
distress, but very loathe to be carried in the manner and the direction they
were so unceremoniously dragging him along. The little black warriors had
already deprived him of two or three of his feet, and they were sawing away
at the remainder of his legs and feet, whilst he was clinging with his large
jaws to a piece of oak leaf; and that the little black fellows were hauling
him, leaf and all, to some terrific fate, was manifested by the prisoner in all
his actions. I had not time then to wait and see how the affair terminated.
Since that case, however, I have witnessed a good many similar ones. It
occurs quite frequently.

The agricultural ant, in his foraging excursions, travels over a wide range,
and will not turn his course for anybody. So, when in his course, he falls
into a range of confederate cities of the erratic ant, he walks on as carelessly
among them as if there was no one at home; and, as a general thing, the
sagacious little braves suffer him to pass unmolested, paying but little atten-
tion to him. But sometimes he meddles too much, and, putting on airs, con-
trary to their notions of propriety, they consider it a national insult, and

[April.

instantly, all that portion of the confederacy are up in arms. Large com-
panies attack him forthwith. It is, however, always a dangerous experiment,
and very often resulis in failure. At the best, there is to the erratic ant, in
these cases of daring, great loss of life. When they make the attack, the
giant intruder, at first, seems to regard it as an affair of a trifling nature, and
with but little concern, strikes about amongst his diminutive assailants
without any apparent anxiety. He occasionally snatches up one of the most
venturesome, and, as if to frighten the rapidly-increasing hordes, or to show
off his great strength, he breaks the backs or heads of half a dozen or so,
but does not kill near as many as he might.

The news of this giant invader of the confederacy soon spreads to every
city, each of which sends out its quota of warriors ; and it is surprising to
note how promptly and with what haste they stream along on the road to the
troubled city. The field around the red monster begins to blacken with the
accumulating regiments of the invaded nation ; and now, when it is too late,
the great red monster begins in earnest to crush and slay every one that
comes in range of his death-dealing jaws ; and, by means of his great
strength and power to crush and destroy everyone upon whom he can clamp
his ponderous jaws, he often succeeds, with the loss of one or more of his
feet, perhaps, in extricating himself from the dangerous thraldom. But
more frequently, the daring little blacks pitch into the strife in such multi-
tudes, and seizing him by every foot, and leg, and horn, and weighing him
down by their numbers, overturn him, clip off his feet, gnaw at his throat,
saw at his waist, and, finally, in the course of half a day, succeed in render-
ing the giant foe harmless. And now, with a grand display of their numbers,
they drag the now helpless victim about in triumph for a time, and then as
many as can get a hold of the dying red ant pierce him in the joints of his
coat of mail, and suck from his trembling, agonizing, prostrate body all the
vital fluids, leaving the perfectly-dry skeleton on the plain, as a warning to
all such adventurous intruders.

About the first of October, or as soon as the atmospheric temperature
begins gradually to lower, the thoughtful little erratic ant, who is, indis-
putably, a practical meteorologist, goes diligently to work, deepening his
habitation. A knowledge of the meteorological indications obtains with all
the species of the ant genus. Hence, we find that, during the summer sea-
son, they throw out from their cells only black dirt — soil; then they are ex-
cavating apartments near the surface, both for convenience to the foraging
laborers, whose duty it is to bring in the supplies, and to obtain a higher
temperature for the purpose of hatching and nurturing the young. But, as
soon as the signs of approaching winter supervene, we see them throwing up
(day, and, among the larger types of the genus, borings of the limestone
rock, even. Thus we learn that they are preparing cells or apartments at a
greater depth. With a perfect knowledge of their physical powers of resist-
ance to the atmospherical changes which are to take place during the winter,
they construct their winter quarters. Accordingly, if we take pains to
ascertain the truth by examining the facts for ourselves, we shall fiud them
excavating their winter apartments at a depth below the line of change — to
where the temperature is uniform at about 48° Fahrenheit. Here, with the
addition of the vital warmth of the swarm, the temperature of their winter
quarters maintains an uniform heat of about 69°. In this the community
remains comfortable and active throughout the season of inclement weather.

16th March, 18G2. This was quite a gala day with this species of ant. At
all their holes everywhere in this vicinity, might be seen great numbers of
their diminutive, white-winged queens frisking about, around the entrance to
their cities, in a very antic style. All the drones, or male ants, were out, too,
running very rapidly to and fro, chasing the queens, who suffered themselves
to be overtaken, receiving the embrace of their lovers quite naturally and
very often. Many of the neutrals were out also, who were engaged in trans-

porting their eggs and young ones, in all stages of growth, from one hole to
another, running rapidly with the tender, maggot-like looking things, to
prevent them, as I thought, from being injured by the sun, which was hot
for the season. Others, again, who were not carrying the young, would dash
up behind the nearest queen, and, in a playful manner, seize her by the
extreme tips of her folded white wings with his calliper-like mandibles,
raise her from the ground, and rush headlong into the nearest hole with her.
The queens did not seem to relish this piece of rudeness, but they submitted
to it with good grace, and soon came frisking back to their lovers again.
I saw hundreds of them carried forcibly into their holes, in the same
playful style, by the workers, who, not unfrequently, snatched them rudely
from the embrace of the males. The males or drones of the erratic ant, un-
like most of the other species, have no wings; on which account it becomes
necessary for the queens to receive their embraces previous to taking their
flight, which they all do instantly, after they are satisfied with their lovers.

The queens or mother ants of this species are not more than half the size
of the workers and nurses of the cities to which she belongs. She is not so
large as a small flea, and yet she takes her aerial voyage alone, and, if the
wind is strong, she may continue her flight many miles. When she descends
to earth again, she immediately cuts off her wings, which are no longer use-
ful, and goes to work to establish a new city.

Just think of the great powers possessed by this small, almost microscopic
insect. Let us recount some of her known attributes. Poised on her tiny
white wings, all alone, and charged as she is, in embryo, with myriad nations
and kingdoms of her species, destined to flourish and perform their parts on
the future life stage, in the grand conflict for subsistence, confidently com-
mits herself to the swift winds, and, while in search of her new home, she
continues her aerial flight, perhaps, for hundreds of miles. She lights at
last, however, and, cutting away her wings, which are no longer necessary,
commences the work of excavating and preparing cells and apartments for
the coming generations. And now, supposing it to be true, that this is the
only ant of that species on the face of the globe, such is her wonderful pro-
lific powers, that it would require but very few short years for her to re- pro-
duce, and fill our yards, and paths, and hearths, and sugar barrels, as thickly
with the countless millions as we now find them.

Mr. Benjamin Smith Lyman observed : I have the honor of presenting to the
Academy a fine Slickenside in the carboniferous conglomerate, found at Ply-
mouth, Luzerne County, Pennsylvania. The Slickenside covers a surface of
irregular shape, eight inches and a balf long in the longest part and sixteen
inches wide ; and is very smoothly and straightly grooved, evidently by the
rubbing of one portion of the rock upon the other, ft bus struck me as inte-
resting chiefly on account of its giving a perfectly satisfactory explanation of
what have been sometimes taken for fossil calamites that had impressed them-
selves upon the quartz pebbles of the conglomerate so as to flatten and groove
them. Such impressions were mentioned by Professor Jehu Brainerd of Cleve-

land, in a paper read before the Cleveland meeting of the American Asso-
ciation for the Advancement of Science, and published himself the next year,
as a principal argument in favor of his theory of the formation of sandstones,
and even conglomerates, solely by chemical deposition. He supposed the
pebbles to have been deposited in a gelatinous state at first, so as to be capable
of receiving the impressions of plants ; and he gives a figure of such an im-
pression resembling a calamite or a coarse conglomerate with the surface of
the pebbles quite flat. I was puzzled by a similar detached fragment of a
slickenside in the conglomerate near Beaver Meadow, in 1859 ; but this speci-
men, from its size and completeness, explains perfectly both that one and the
one figured by Professor Brainerd.

Aside from the striking extravagance of Professor Brainerd's theory, and
from this specimen's refutation of one of his best arguments, another argument
against him, furnished by his own figures, may perhaps properly be mentioned
here. A gelatinous pebble flattened by pressure on one side would, manifestly,
be distorted on other sides, and a number of such pebbles lying side by side,
affected by the same pressure, would have analogous distorions. In Professor
Brainerd's figure of the so-called fossil calamite, the pebbles flattened on one
side show no such distortion, but retain on every other side their rounded,
water-worn look ; so that the general appearance is, in effect, that of pebbles
cut in two, instead of flattened down by pressure. The same can be said of
the pebbles in his figure of the conglomerate resting with flat bottomed peb-
bles on the soft red shales, which he says is a very common occurrence, and
which forms his other best argument in support of his theory.

Dr. Le Conte made some remarks on the subfamily Clavigeridae, of Coleoptera.

He described briefly the structure and habits of these insects, and pointed
out the distinctive characters of the three described genera, Claviger, Adranes
and Articerus, to which he added a fourth, F u s t i g e r.

This new genus agrees with Articerus in having eyes, but differs in the
structure of the antenna?. These organs in Articerus are broad, without
distinct basal articulation, but in Fus tiger consist of a long subconkal
mass, gradually broader externally, truncate, and covered with a sponge of
hair at the tip, and marked with four or five indistinct transverse sutures,
showing that it is composed of closely connate joints ; between this subcorneal
mass and the head is a distinct short basal joint, projecting beyond the fovea
in which the antenna is inserted. The eyes are oval, situated on the sides of
the head, and composed of seven or eight moderately large lenses. 1'he tibiae
are not dilated as in Articerus.

The four genera thus form two series, of two genera each :
A. Eyes wanting :

A n ten me 6- join ted Claviger.

B. Eyes distinct, composed of a few aggregated lenses :

Antenna? with one short basal joint, and a long club

having traces of transverse sutures F u s t i g e r .

Antennae (? without basal articulation), with a broad club

The distribution of these genera is peculiar: Claviger is found in Europe and
Asia ; Adranes in North America ; Fustiger in Brazil, Syria and North America ;
while Articerus, with the exception of a species found in Copal, is confined to
New Holland.

The species of Fustiger are : 1. F. braziliensis, (Articerus braz. West-
wood, Trans. Ent. Soc. London, 2d ser. iii. 277, pi. xvii. f. 5,) from Brazil;
2. F. syriacu s, (Articerus syr. Saulcy, Ann. Ent. Soc. France, 1865, p. 15,)
from Syria ; and 3. A new species from Tennessee, which will soon be described
by Dr. Brendel, who is now occupied in studying the Pselaphidae of the United
States.

Westwood mentions, in the description of the Brazilian species, and exhib-
its in the figure the short basal joint of the antennae, but does not allude to the
obsolete transverse sutures of the mass of the antennas.

Saulcy describes the structure of the antennae very accurately, and it is
owing to his observation that I have detected a very short and indistinct joint
between the visible basal Joint of the antennas of Adranes, and the bottom of
the frontal foveas in which they are inserted.

Dr. Leidy remarked that Mr. J. F. Clew, one of the proprietors of the salt
mine of the Island of Petite Anse, Louisiana, had that day called upon him,
announcing the donation to the Academy of a mass of 150 lbs. of pure rock
salt. Mr. Clew further informed him of an interesting fact in connection with
the history of primitive man. The salt mines of Petite Anse were discovered
during the late rebellion. A salt spring had been previously known to exist.
During the war, as this failed to produce the amount of salt required, a well
was sunk in the hope of procuring a greater supply. At the bottom of the
well the workmen met with a solid rock which turned out to be pure salt.
This is covered with about fifteen or more feet of soil, mainly composed of sand
and mud. A specimen of this soil having been submitted to Dr. Leidy, he was
surprised to find mingled with it grains of precious garnet and olivine. Mr.
Clew stated that a number of pits had been opened to reach the salt. In
several of the pits at the depth often or fifteen feet they discovered in the soil
bones of the Elephant, well preserved, and beneath these, within a few inches
of the rock salt, abundance of matting. Portions of this m ttting, exhibited to
Dr. Leidy, were composed of a tough, flexible, split cane, and were plaited
diagonally. The pieces were well preserved, and evidently specimens of
human art. On being asked the question, Mr. Clew said he was under the
impression that some stone implements had also been found in a similar
position, but he was not certain. He further added, that at the sides of one of
the pits, bones of the Elephant, and beneath them pieces of matting, could yet
be seen, as they had been allowed to remain undisturbed. The facts were so
interesting in connection with these remains, and the geology of the Island of
Petite Anse, that Dr. L. thought a competent person should be sent there to
make an exploration. Mr. Clew has offered every facility to any one disposed
to undertake the investigation.

Notes on Some Members of the FELDSPAR Family.
BY ISAAC LEA.

I have been much interested for several years past in observing and col-
lecting the varieties of the Feldspar Family of Chester and Delaware Counties
in this State.

Finding in many places that, where the intrusive Serpentine appears, there
were usually to be found the finest and more vitrious varieties of Feldspar, I
visited all such localities, and thus have brought together, perhaps, more of
them than any other mineralogist who has searched in these counties. My
object in these researches has been solely as to their external characters, con-
nected with the matter which gives to them color, so far as microscopical ex-
amination could enable me to effect it.

Among the numerous varieties which I have brought together, I think there
are three which have not been before observed. One is of a compact struc-
ture, almost without cleavage, and of a fine green color, approaching, as
regards tint, to aqua-marine, and is semi-transparent. Another, which
usually accompanies the first, and often passes into it, as Leelite does into
Feldspar, has always a definite and well characterized cleavage, the surface
of which presents an agreeable pearly appearance, sometimes satin-like.
This is usually white or grayish, sometimes inclining to a pale purplish hue,
particularly toward the edges of the specimens, and which seem to have been
enveloped in Alhite. Along those edges where the purplish hue is stronger, I
could, in all cases, detect small thin spangles or plates, such as constitute
Sunstone, — Aventurine Feldspar — with reddish or wine-color internal re-
flections.

These reflections are minute, usually microscopic, and always, I believe, of
a hexagonal form or the modification of that form.

For the green mineral, I propose the provisional name of Lennilite, having
found it only near the village of Lenni, in Delaware County. For the pearly
variety, I propose that of Delaioareite, having first found it in Delaware
County, among the Serpentine rocks, between Grlen Riddle and Lenni. Subse-
quently, I found specimens in Chester County, near to West Chester.

The third is a variety of Feldspar which is more laminate and glassy, of a
dull bluish green color and semi-transparent, which has through the mass
usually very minute internal bright crystalline hexagonal plates giving
very bright reflections. This is found at Blue Hill, about two miles north of
Media, and is an exceedingly interesting mineral. I found a specimen very
similar to this, but rather more blue, some three miles southwest of West
Chester, which had not, however, any plates with reflections, but, with a
high power, numerous small, black, thin, prismatic crystals were observable.
For this, I propose the name of Cassinite.

It had been known for many years that Sunstone proper existed in the
Homblend Rocks of Chester County, near to Kennett Square. This I found
in sufficient quantity and perfection to institute a good examination into the

[May,

forms of these reflections. Under a high power, I ohserved perfect equal-
sided hexagons, with nearly all possible modifications of that form, by more
or less unequal replacement of some of the prismatic sides ; thus, some assum-
ing a triangular form, some that of rhombs and rhomboids ; some of the lat-
ter being almost linear. These plates are sometimes imperfectly formed, the
boundary lines being occasionally irregular and broken, exhibiting one, two,
three or four sides, and sometimes no part of the sides present a right line.
They usually lie parallel with the principal cleavage of the Feldspar, and,
when the rays of light strike their bright surfaces, the reflections are exceed-
ingly brilliant. Under the microscope, with a bright light, it will be observed
that some reflections are blue, others green, purple, red and yellow. Some
of the specimens of Sunstone show parallel lines on the edges of the cleavages
parallel to the prismatic sides of the Feldspar, which are evidently occasioned
by the regular deposit of the layers. These are quite different from the fine
parallel minute striae which lie on the principal faces of the cleavage, and
which can only be observed with a high power. Neither of these are con-
stant. These spangles or plates are so thin, that I have been unable to
detect any perceptible thickness on their prismatic sides. These very inter-
esting plates in Sunstone have been known for a long time, but I have not
been able to find any analysis of them.* Kenngott states that they are Go-
thite, hydrated-per-oxid of Iron (Fe 0.,HO). Sheerer says that " the Aventu-
vine character is owing to minute particles of Specular Iron.] I doubt this,
as the resplendant crystals are usually semi-transparent, reflecting various
colors, as mentioned above. There are in most varieties another set of de-
posits, which are much rarer, and present opake, black masses, usually taking
the same hexagonal form and its modifications, but often without any regular
form. These may be of the same metallic substance iu a different state of
oxidation, not transmitting the rays of light.

Fine specimens of Moonstone are found in Albite, in Delaware County, west
of Media, but this species of Feldspar does not give out its beautiful bine
color by reflection from any foreign body, but by the absorption of all the rays
of light but blue, and this owing to some arrangement of its atoms not yet
understood.

In the examination of various Feldspars with, high power of the microscope,
I found in nearly every one which was not entirely white, that more or less
foreign matter in a crystallized state, was included in their composition. In
the green compact variety which I have described above, and proposed to call
Lennilite, there was nothing detected, nor was there in the ordinary green
Feldspar of Mineral Hill, near Media, except that in the latter locality there
have been specimens found of a glassy structure, and with clear double
cleavages, in which reddish spots were interspersed, which spots were always
colored by the presence of these crystalline plates, having beautiful bright
reflections, and of the usual hexagonal form.

I ought to mention here, in connection with these beautiful brilliant plates
in Sunstone, that Prof. Rood, of Columbia College, New York, some time
since, made a " Micro-Stereograph " of a thin plate of Sunstone from Arendal,
Norway. In this he succeeded admirably in displaying these numerous modi-
fications of the crystals, which were enlarged and photographed on paper ;
thus bringing those interesting forms with great perfection to the recognition
of the unaided eye.

I proceed now to the results of my microscopical examinations of various
Feldspars, in which I found more or less of these minute crystalline forms.

* Aventurine Quartz is also called Sunstone, and is considered of some value as a stone of luxury,
liut it has not reflections as brilliant as those of Feldspar ; nor are they, so far as I have been able
to observe, crystallized plates, but their irregular deposits are of the same brown and red color,
and they may be Gothite.

In the dark, nearly black Labradorite of the Adiroudac Mountains, there
were only to be found dark, irregular, uushaped spots.

In the nearly black opalescent portions of Labradorite from Warwick,
Orange Couuty, N. Y. , were very minute imperfect black crystals, while
scattered throughout there are larger transparent, imperfect forms of irregular
crystals, which have the appearance of being hollow points.

A rolled fragment of pale purple Feldspar from Easton, Pa., contained
hexagonal plates, but generally these plates were found to be irregular and
broken.

A Black Feldspar found near West-Chester — a small fragment nearly an
inch square — was found to possess very thin prismatic black crystals, lying
in various directions, but principally in one direction. There were also
scattered throughout a few very black spots, some of which were disposed to
take the hexagonal form.

Labradorite from Scotland, with a fine colored surface, presented minute
reflections. Under a high power, a few brown hexagonal plates were
observed, with very numerous black, attenuated, prismatic crystals, and
some short thick ones.

A bluish lead-colored glassy Feldspar, from near West-Chester, presented
acicular black lines all in the same direction. These were usually somewhat
long, much more so than I have observed in any other specimens which I
have examined. Occasionally an opake, black, rhombic crystal was
observed.

A dark variety from Lenni, passing into Leelite, possesses very minute
black, attenuated prismatic crystals.

Fetid Feldspar (Necronite ?) from the Vanarsdale Quarry in Bucks County,
Pa., has microscopic black crystals, imperfectly formed, but with a tendency
to hexagonal form.

A Salmon- colored Feldspar, from near Lenni, was found to possess many
elongate black rhomboids, and some few imperfect reddi&h hexagonal plates.
One of the rhomboids is partly black and partly red, showing that the crystals
of both colors are of the same substance.

A specimen of a darker salmon color, found by Mr. John Cassin, many
years since, attbe old Molybdena Mine, near Chester, Pa., has the appearance
of Perthite, but there were no reflections to be observed in it, only presenting,
occasionally, black masses. The deep color of this Feldspar arises from the
close approximation of irregular opaque brownish masses.

A very pearly specimen of Delawareite found near West-Chester, con-
tained rather large reddish plates and many opake black crystals, some elon-
gate, others triangular, hexagonal, &c.

Among the pearly specimens of Delawareite from Lenni is a fine purplish
one with blood-red crystals, which are much larger than usual, and one is
much longer and narrower than usual. In one of the pieces I observed a
black curved object which presented a serrated side, reminding one of the
notches of a Graptolite. It is probably Tourmaline.

The remarkable fine Sunstone obtained by Mr. Jetferis and myself in Chester
County, Pa., present under a high power a great number and variety of bril-
liant red crystals of a hexagonal form, and of every modification of this figure.
The reflections of the surface of these crystals give beautiful colors. Occasion-
ally in these specimens where the plates are numerous and close, an area
may be observed without any color, being clear, but retaining the hexagonal
form and its modifications, the area being surrounded by reflections of red,
blue, &c.

In the very peculiar greenish blue, lamellar Feldspar, from Blue Hill, two
miles north-west of Media, Delaware Co., I found very numerous, small reflec-
tions of the usual modifications of the hexagon. This is a very pure and glassy
species, and is of rare occurrence. It is found in the Serpentine rocks, and
presents an entirely different appearance from Sunstone proper, which is found

in the Hornblend rocks of Chester County, the texture of the Feldspar and the
reflecting plates being peculiar. I propose for it the provisional name of Cas-
sinite, Mr. John Cassm having first called my attention to this glassy, bluish-
green Feldspar. The possession of the reflecting plates had not been observed
until I had discovered it by an examination with the microscope, but which
when pointed out may be seen by the naked eye.

A gray satin-like specimen of Delawareite exhibited no red reflections, but
there were some small, black, microscopic crystals chiefly of very elongate
hexagons ; some were irregular and not long.

A green and red mottled Feldspar from Mineral Hill, near Media, presented
reddish groups of reflections here and there throughout the mass. Under a
high power these plates were observed to be of the usual modified forms of
the hexagon, that of the rhomboid prevailing while the hexagonal form itself
was found only in rarer instances. The color of these plates varied from a
blood red to a pale wine red, and are very small and numerous. This is a
remarkably beautiful mineral and is I believe very rarely now found. I have
found a single specimen and the only other specimens I have seen, were
found some thirty years since.

In the beautiful Sunstone of Chester County, near Kennett Square, I found
many reflecting plates of various shades of red. These plates are very numer-
ous and usually elongate rhomboids, but the hexagonal form and all its modi-
fications are found of various sizes when examined with a high power. There
were observed also many black irregular spots, and some of these had irregu-
lar hexagonal margins. Interspersed throughout could be seen very numer-
ous short, black, attenuate, prismatic forms, much more numerous and ap-
proximate to each other than was the case with the reflecting plates.

The fine Sunstone of Arendal, Norway, presents very remarkable reflections
of not very minute plates. The Feldspar is clear and pure, and these reflec-
tions numerous and very brilliant. The hexagonal form and its modifications
are very perfect, and the color pure and translucent, varying from dark red
to light wine color. Many of the rhomboids are very elongate. Occasionally
opake black plates were observed, and the same may be said of other Sun-
stones generally.

Chesterlite, from Chester County Poor House, quite to my surprise, presented
here and there hexagonal plates. In one specimen I detected a remarkably
fine hexagon of a deep red color.

Perthite, from Perth, Canada West, is a very dark salmon-colored variety
of Sunstone. and I found in it the same hexagonal form and its modifications,
but the plates were darker in color. There were mixed with these some
opake black ones, similar in density and form to those which are found in
the Sunstone of Chester County.

In Peristerite, from the same locality, I found very numerous minute black
crystals, generally elongate rhomboids, very like, if not toe same with, com-
mon Labradorite, to which it seems to be very nearly allied.

Observations on CHAEIETES and some related Genera, in regard to their Sys-
tematic Position ; with an appended description of some New Species.

BY DR. CARL ROMINGER.

Chaetetes has, by its tubular structure and the transverse diaphragms, di-
viding the tubes, a strong resemblance to Favosites, and was for this reason
generally considered to be a member of the Favositoid family.

In the following pages I shall try to prove this to be an error, and to de-
monstrate its immediate connection with forms which are considered to be
Bryozoa.

It has been asserted that transverse diaphragms have never been observed1

1866.] 8

114 PROCEEDINGS OF THE ACADEMY OP

in the tubules of any Bryozoon, (Milne Edwards et. H. Arch, du Museum, torn.
v. p. 278,) but some Jurassic specimens of Heteropora in my possession ex-
hibit with the utmost distinctness their tubules divided by horizontal dia-
phragms. It would be difficult to distinguish a vertical section of them,
from a similar section of a Chaetetes, if the tube-walls of the first were not
perforated by densely crowded, very minute pores, while the walls of a Chae-
tetes are imperforate.

Fisher, the author of the genus, informs us that the tubes of Chaetetee
multiply by division, while other observers, in specimens believed to be
Chaetetes, could only see a multiplication of tubes by lateral gemmation, and
therefore, to avoid the difficulty, created the genera Stenopora and Monticu-
lipora, for these specimens. Milne Edwards is, to my knowledge, the only one
to affirm Fisher's observation to be true, (British Fossil Corals, p. 264,) but he
does not specially designate the species on which he made his observations,
and subsequently places all the species he formerly named Chaetetes, under
the genus Monticulipora.

I know of only one fossil resembling Chaetetes, in which the tubes are
multiplied by division ; this is the genus Tctradium, whose tubes regularly di-
vide into four parts, but there is no reason to suppose this to have been the
type for Fisher's genus Chaetetes, nor seems it probable that Milne Edwards
had it under consideration. The structure of Chaetetes is considered to be
exclusively tubular.

If we observe the different forms of Chaetetes, we will find some with con-
tiguous polygonal orifices, and thin intervening walls. Others we will see
with the tube mouths rounded, only partially contiguous, and with a num-
ber of smaller angular openings dispersed between them. In still others,
the orifices are circular, not in contiguity, and surrounded on all sides by
smaller angular openings. A vertical section through these different kinds
will, at first sight, not exhibit a corresponding variety of appearance ; we
find the whole corallum to be an aggregation of tubules, which are divided
by transverse diaphragms ; a closer examination, however, will reveal to us,
in the last mentioned forms, two sorts of tubules : larger ones, more or less
circular in the cross-section, with straight diaphragms at variable, sometimes
quite remote distances ; and smaller ones, which are angular, with more closely
approximated diaphragms ; but the different tube segments, cut off by the di-
iphragms, are not always so regular as the nature of a tube would require it ;
■some are projecting over the others, and joining with the adjacent segments
in zigzag lines, which is a sure evidence that we have no real tubules before
-us, but merely vertical rows of independent cells, which being crowded in
between tubes, assumed themselves the shape of tubules.

An interesting family-mark, common to Chaetetes, and to a number of
other genera related to it, are the peculiar maculae noticeable on their sur-
face. In specimens of prevalently tubular structure, these maculae are con-
stituted by aggregations of larger tubes than the others ; at the same time we
see the surface at these places frequently elevated into small monticules. In
other specimens, where the intertubular cell-mass is well developed, these
maculae are contrasting with the other surface by their entirely cellulose
structure, and it is not uncommon to see these spots depressed, instead of
being elevated.

The orifices of Chaetetes are generally open, or exhibit some distance be-
low the surface their diaphragms, which appear to be perfect. It is, however,
not rare to find specimens in which the tubules are closed by opercula with a
central opening. In specimens of Chaetetes rugosus and ramosus, from the
blue limestone of Cincinnati, a part of the surface frequently has closed tub-
ules ; their appearance assumes hereby an entirely different character, which
reminds one greatly of the ramulets of Melicertites from the Oolite forma-
.tiou. Also .of Chaetetes frondosus, I have some specimens exhibiting opercula.

[May,

NATURAL SCIENCES OF PHILADELPHIA. 115

In the first two species the opercula are slightly convex, in the latter, con-
cave, and with an excentric opening.

Several species are decorated with spinules, rising from the margins of the
tube orifices, and from the interstitial spaces. One of these, which attracted
the attention of Milne Edwards, induced him to create for it the genus De-
kayia. This spinulosity is not a confluent character, and has, in my estima-
tion, no more importance than the hairs of a plant have, in regard to its gene-
ric position.

The so called Dekayia aspera occurs in the blue limestone of Ohio and
Indiana, in which several other spinulose forms are found. One of them
grows in small ramulets, with somewhat oblique, very minute orifices ; some
of its specimens are entirely smooth, without showing any signs of detrition ;
in others the surface is raised in scarcely perceptible, obtuse nodules ; and
finally, some are found with a perfectly hirsute surface. Also some speci-
mens corresponding with McCoys Nebulipora lens, are decorated with quite
prominent spinules ; likewise some larger hemispherical masses, considered to
be Ch. petropolilanus, and a species similar to Chaetetes frondosus.

From the shales of the Hamilton group of New York and Michigan, I know
also several species of spinulose Chaetetes forms.

The stellate form of orifices, which is least expected to be seen in Chaetetes
or in a Bryozoon, nevertheless is represented in some species of the Chaete-
tes family.

A few specimens found at Cincinnati, which in all particulars agree with
Chaetetes frondosus have from three to five longitudinal ridges projecting into
their tube cavities, by which the orifices acquire a florifortn shape. In other
specimens of the same species the orifices are round, without any traces of
stellate character; even in the mentioned specimens, not all orifices are stel-
late. The stellate orifices of Callopora Jlorida are made known by Hall ; sev-
eral other species of it are of the same character, and also in the genus Fis-
tulipora we will meet with floriform orifices.

The question now is, have we to consider this stellate character as a seri-
ous objection to the bryozoic nature of Chaetetes and the allied genera ?

I think not, for two reasons : 1. This radiate structure cannot be the ex-
ponent of a character which is essential to these organic beings, or it would
be invariably developed. 2. These projecting lamellae are not the equivalent
of the radial organs in corals. Their number is not constant enough for that,
and their distribution indicates frequently an unsymmetric bilateral, and not
a radial plan. In some species there are only two such projections on one
side of the tubes, while the other side is smooth ; in others, with a larger
number of lamellar projections, they generally form two opposite groups,
and are rarely found disposed at equal distances around the circumference.

The relations between Chaetetes and some acknowledged bryozoic forms of
the paleozoic era are so great, that if radial structure should be considered
incompatible with the polyparium of a Bryozoon, I would rather remove
the whole assemblage from the bryozoa, than to separate Chaetetes and some
others from them.

In the blue limestone of Madison and Richmond, Ind., a well marked form
of Chaetetes is found in abundance, which I do not see described. I propose
for it the name Chaetetes quadratics.

It grows in coarse ramifications, with an even or slightly monticulose sur-
face. Tube orifices vary in size in different specimens from one-fourth to
one-third of a millimeter ; those on the maculae are somewhat larger ; they
are contiguous, polygonal or quadrate, separated by thin walls. Intertubular
cells entirely wanting.

The quadrate tube form is particularly obvious on the terminal surface of
branches, or on transverse sections. On the sides of the branches the quad-
rate tube form gives the surface a fanciful appearance, which I cannot bet-

ter explain than by comparing it with certain decorations of watch cases, con-
sisting of concentric circle lines crossing each other. Chaetetes pavonia, with
the synonytne Ptylodictya pavonia D'Orbigny, is described by Milne Edwards
amongst the Chaetetes forms of the Cincinnati limestone.

This species has indeed a great resemblance to the group to which Ptylo-
dictya belongs. It grows in double, thin laminae, separable in two folia,
which have on the inner side a dermatic concentrically wrinkled and striated
crust, exactly similar to the separated leaves of Ptylodictya. The tubes be-
gin with prostrate, thin walled ends, and become rectangular to the surface,
by abruptly bending upwards ; the erect part of them exhibits very thick
walls. The orifices are contiguous, slightly dilated, and arranged in undu-
lating rows, which, crossing each other under oblique angles, make their
outlines more or less regularly rhomboidal. The outlines of the single tubes,
however, are polygonal, and may be plainly distinguished in the centre of the
massive interstitial spaces. Diameter of tubes one-sixth of a millimeter,
somewhat larger on the monticules, which are little elevated and are dissemi-
nated over the surface at a distance of three or four millimeters. No dia-
phragms observed. Intertubular cells wanting.

This species would be entirely in correspondence with the genus Phaeno-
pora of Hall, but the entire absence of intertubular cell-mass, which is
always, to some extent, developed in the species of Phacnopora, is a difference
of some importance, which, however, will be diminished, after we have seen
in Chaetetes species with abundant intertubular cell-mass, and other species
composed of tubules alone, with all intermediate forms placed between
them. It is also to be noticed, that all the specimens of Chaetetes pavonia
which I have seen, appear to be the terminal explanate ends of the fronds,
while at the basal ends the cellulose tissue may be devt-loped to some degree.
This is decidedly the case in a small ensiform bryozoon of very similar
structure, and occurring in the same association. The pointed basal ends of
these specimens have a large proportion of cell-mass entering into their
structure, while the upper portions are almost exclusively tubulose.

Chaetetes decipiens, nov. spec.

Occurs in association with Ch. pavonia, to which it is so surprisingly simi-
lar that, even for an experienced eye, it becomes almost impossible to dis-
tinguish the two species without the help of a lens.

It grows in entirely similar thin double leaves ; the surface is covered with
the same sort of monticules, composed of larger tubules : the orifices are simi-
lar in size and distribution, but a closer examination will reveal sufficient
constant differences between the two.

The latter species has an abundant cell-mass interposed between the tu-
bules ; its tube-walls are thin, with not dilated and not contiguous orifices ;
the two leaves composing the lamina? are not so clearly defined, and not sep-
arable, and on vertical sections the vesiculous cell-rows interposed between
the tubules, which themselves are also sometimes septate, will distinguish it
at once.

The thick tube-walls in the one, and the intertubular cell-mass in the other,
will produce on the naked eye a similar impression, which disappears under
the magnifier.

This species has likewise much similarity with Ch. frondosus, but it is more
delicate in all respects, and in Ch. frondobus the intertubular tissue is consid-
erably less developed, its tubules being usually in immediate contiguity.

The genus Callopora of Hall, comes so near to Chaetetes that it may be well
characterized at once, by saying it is a Chaetetes with abundantly developed
intertubular cells. Chaetetes Flelcheri, (Milne Edw.) for instance, is in all par-
ticulars a Callopora.

The opercula, described by flail in Callopora eleyantula, are of the same
general form as in Chaetetes, but a peculiarity of them is, some five or six

•

elevated ridges, radiating on the surface of the opercula, from the margin of
the central opening to the outer circumference. In a species of Fistulipora,
subsequently to be described, I found opercules of exactly the same struc-
ture. Also some species of Callopora, with a spinulose surface, are made known
by Hall, which exhibit no essential difference from the spinulose species of
Chaetetes.

The floriform orifices of Callopora floi-ida, Hall, and laminata, Hall, have
been occasionally mentioned before. The same stellate character of the ori-
fices is developed in a species from the carboniferous limestone of La Grange,
Missouri, (Keokuk Limestone.)

Callopora missouriensis nov. spec.

From an incrusting basal expansion branching nodose stems grow up.
Diameter of stems four or five millim., orifices one- eighth of a millim. wide,
distant from two to four of their own diameters. Form of the orifices some-
times only slightly sinuose, but in some finely preserved specimens, having
the form of a five-rayed star, with a spinula on each of the inward project-
ing angles.

The intermediate spaces are filled with open angular cells, much smaller
than the tubules. In vertical sections the tubes do not exhibit any dia-
phragms ; the intertubular cell mass forms very regular vertical rows, having
the appearance of septate tubules.

The genus Trematopora Hall, naturally succeeds Callopora. The principal
differences from the latter genus are the elevated rims of its tube orifices, and
the generally closed interstitial cells, which are less similar to tubules than
in Chaetetes, and show decidedly their vesiculous nature. The tube dia-
phragms are not often developed, but there is no difficulty to find specimens
in which their existence can be demonstrated.

Not all species united by Hall in the genus Trematopora properly belong
there ; for instance, Trematopora sparsa, striata, and others. On the other
side, I think several species ought to be united with it, which are placed in
other genera; as Ceramopora foliacea, Diamesopora dichotoma, etc.

McCoy's species of Fistulipora seems to have exactly the same structure with
Trematopora, but McCoy had much less correct ideas of the affinities of his
genus than Hall had; the latter expressly states the similarity of Callopora
and Trematopora with the Bryozoa, and was only prevented from giving them
their proper place by the existing prejudice, that the tubules of Bryozoa
never have any diaphragms.

1 take Trematopora and Fistulipora as being identical, and will use the
name Fistulipora in a more extended sense, applying it to all the species
which agree with it in anatomical structure and general surface characters,
without to inquire specially at this place, how far a division into some sub-
genera, would be practicable.

Fistulipora is represented by a considerable number of species, during the
whole paleozoic era. A striking feature of nearly all its species are super-
ficial macule, analogous to those of Chaetetes ; they are of exclusively cellu-
lose structure, and have frequently a subregular stellate form.

A fair representation of these macula^ is given (Arch, du Mus. Tom. v. Tab.
20, f. 5,) in the figure of Chaetetes Torubine, which itself is, to all appearances,
a Fistulipora.

The projecting tube margins of Fistulipora are in most of its species
oblique to the surface, although the tubes themselves have generally a rec-
tangular position to it, excepting the smaller ramose forms, and the earlier
stadia of growth in laminar expansions, where the tubules are prostrate in
the beginning, but soon elevate themselves under an abrupt angle and be-
come rectangular.

The tube orifices are generally circular, or oval, but sometimes sinuate, or
even stellate, like those described in Chaetetes and Callopora. Also opercu-

la, of similar structure to those of the former genera, are sometimes noticed
in specimens of Fistulipora. The central opening appears to have been closed
in some of the opercula by a subsequent solid deposition; we find, at least in
all the perfect opercula, the central portion forming an offset from the sur-
rounding marginal part.

Fistulipora is quite polymorphous ; we find its species incrusting, and in
free expansions, with orifices on one side only, or in double leaves, with ori-
fices on both sides ; they grow in hollow stems, or in strumose cystical form,
or in solid ramifications, or in undefined large masses.

One, or several, of these forms are generally significant for a certain species.
but I think, in the systematic arrangement of the Bryozoa, too much weight
has been given to their external form and to the manner in which they grow.

For further elucidation of my general remarks, I will append the descrip-
tion of a number of species of Fistulipora which are new, or whose anatomy
was not fully recognized before.

Hbllipora (Constellaria) antheloidea,

Is the oldest and at the same time the most marked form of Fistulipora.

Its circular tubules with projecting rims, the vesiculous interstitial cell-
mass, the monticulose maculae with a star-like depressed cellulose centre, re-
present, in ideal perfection, the principal characters of the genus.

In this place I take occasion to mention a lower Silurian fossil, whose nature
is only imperfectly known, and which resembles in its structure Fistuli-
pora.
Stromatocerium kugosdm Hall.

By its external appearance, it has been generally confused with Stromato-
pora, but this latter has a widely different structure and belongs to the Petro-
spongiae.

Slromntocerium rugosum grows in large subglobose masses with an undula-
ted monticulose surface. Vertical sections show a series of superimposed
laminae, on which the naked eye can scarcely recognise organized structure;
under the magnifier we find it composed of small, subparallel, simple tubules,
and of a comparatively coarse vesiculous cell- mass surrounding the tubules.
These cell-vesicules are convex above, concave below, spread out in horizontal
layers, and not in vertical rows ; the size of the vesicules is very unequal and
varies from a half to one millimeter in the horizontal direction, about half as
much in the vertical sense.

Diameter of tubules one-sixth of a millimeter ; distance between each other
about half a millimeter.

The more delicate surface characters cannot be recognized, on account of
the unfavorable state of preservation of the specimens.

According to Hall, it is found in the Black River limestone. My specimens
are from Madison, Ind., where it occurs in association with Favistella stellala,
in the upper strata of the Hudson River group formation. Some of the best
specimens, however, I found in the drift deposits of Michigan.

The Clinton group, and, in particular, the Niagara group, contain a good
many species of Fistulipora structure — tue Trematoporas of Hall.

In regard to a few of them, I have to make some remarks.

Trematopora tubulosa of the Clinton group, and Diamesopora dichotoma of the
Niagara group, combine exactly the same internal structure with their
external similarity of form.

The inner face of their hollow steins is covered by a delicately-wrinkled
dermatic crust. Their tubules are arranged in oblique rows, becoming some-
what irregular by the slightly-developed maculae. The basal portions of
the tubules are prostrate, and in immediate contiguity; but, by abruptly
bending up to the surface, leave a more or less considerable space between
the erected tube ends, which is filled out by cellulose tissue. This cell-mass
is generally found homogeneous, and allows no discrimination of cells. A

[May,

few specimens, however, may always be found which exhibit with sufficient
distinctness the outlines of the tissue vesicules.

Trematopora tubulosa could, for this reason, with propriety, be placed under
the genus Diamesopora ; but Diamesopora itself, again, so much resembles
Trematopora ossiolata, that I would rather see the genus Diamesopora given
up, by amalgamating its only representative with Trematopora.

The species named by Hall, Ccramopora foliacea, is, in all respects, corres-
pondent with the other Trematoporas. It grows in double leaves, which may
be separated in two folia, with a dermatic crust on the interior face of the.
two leases. Its tubules are, as in the former species, prostrate, and make an
abrupt bend to the surface ; the inter-tubular cell-mass exhibits its structure
with the greatest distinctness.

Diameter of tubules one-sixth of a millimeter. From Ceramopora imbricata,
the type of the genus, it differs essentially. More natural would have been
its combination with Rhinopora verrucosa, which has the structure of Fistuli-
pora, and the exterior form in common with it.

In Rhinopora verrucosa, the maculae are represented by elevated, branching
and anastomosing ridges, which are lined with tube orifices of somewhat
larger size.

FlSTULIPORA NEGLKCTA nOV. Spec.

Convex, undulating, laminar expansions of a few millimeters thickness,
with a wrinkled epitheca below. Tubules one-fourth to one-third of a milli-
meter wide, with quite projecting, oblique, oval orifices, forming a sharp lip
on the outer side, and gradually lost in the general surface on the inner side.
They are arranged in closely-set subregular rows, which are interrupted by
small, little conspicuous maculae.

Locality. Waldron, Ind , and Rochester, N. Y., in the shales of the Niagara
group.

Fistulipora Halli nov. spec.

Undulated, free or incrusting expansions, with a wrinkled epitheca below.

Tubules one-sixth of a millimeter wide, orifices oval, with au abruptly-
projecting lip on the outer side, and arranged in subregular rows, which
keep a distance of about one tube diameter. Macula; quite conspicuous,
sometimes slightly elevated, of irregular substellate form.

This species has much resemblance to Ccramopora foliacca, but it does not
grow in double leaves as the latter.

Locality. Waldron, Ind., Rochester and Lockpcrt, in the shales of the
Niagara group.

In the upper strata of the Helderberg group, and in the Hamilton group,
Fistulipora is represented by numerous species. The smaller ramose forms,
which are so frequently met with in the Niagara group, are rarely seen in
this horizon ; larger laminar expansions, or massive tuberoso-globose forms,
prevail here.

Fistulipora lunata nov. spec.

It grows in tortuous thick laminap, with a wrinkled epithecal crust below,
or more frequently in distorted, very irregular masses, consisting of several
laminae, which are grown together with their epithecal sides. The tubules
are not angular to the surface, with prostrate basal ends as usual. Size of
tubules one-fourth of a millimeter. Orifices with moderately-elevated mar-
gins, rotundato-semilunar, with two dent-like projections into the tube
cavity at the concave or flattened side, which continue as longitudinal ridges
down the cavity of the tubes. Distribution of orifices without any apparent
order; distance a little over their own diameter. Tube diaphragms some-
times developed, frequently wanting.

Intertubular tissue coarse-celled; cells arranged in subregular vertical
rows.

from which irradiate depressed cellulose spaces, giving the surface an orna-
mental appearance, very similar to Hellipora antheloidea.

Drift specimen belonging to the corniferous limestone.

FlSTULIPORA STELLIFERA nOV. Spec.

Double leaves separable in two folia ; surface raised in low monticules,
distant about four millimeters from one centre to another.

Orifices linguiform or irregularly oval, one fourth of a millimeter wide in
the larger diameter, surrounded by an elevated rim. A few larger and more
projecting orifices are generally noticed on the monticules, from the summits
of which narrow, cellulose, bifurcating spaces irradiate. In places to which
these cellulose radii do not extend, the orifices are closely approximated.

Locality. Thunder Bay, Lake Huron, in the shales of the Hamilton group.

FlSTULIPORA SULCATA nOV. Sp.

Thin simple lamina?, with an epitheca below. Orifices one-fourth of a
millimeter wide, irregularly linguiform, surrounded by an elevated margin,
closely approximated and disposed without any apparent order. Maculae
having the form of elongate narrow foveae, which send out some radiating
furrows.

Hamilton group.

FlSTULIPORA MINUTA nOV. Sp.

Undulated lamina?, only half a millimeter thick, with an epitheca on the
lower side, and raised in low rounded monticules on the upper face.

Tubules one-eighth of a millimeter wide, irregularly oval, distant from
each other somewhat more than one tube diameter. Maculae little con-
spicuous, on account of the minuteness of the fronds.

Large undulated expansions, from a few millimeters to one centimetre
thick, and with an epithecal crust on the lower side.

Surface elevated in monticules of about five millimeters distance. Tubules
one-fourth to one-third of a millimeter; of somewhat larger size on the
monticules.

Cellulose macula? only feebly developed.

Orifices rotundate, forming a prominent lip on the exterior side, equally
distributed over the surface, holding a distance of a little more than their

millimeter wide. Surface finely spinulose or granulose, exhibiting seemingly
dilated polygonal orifices, but actually it is the luxuriant spinulose inter-
tubular cell mass which forms the polygones, and obscures the tube mouths
within its meshes. Occurs with the former species.

FlSTULIPORA ElUENSIS HOT. Sp.

Undulated and distorted laminar expansions one or several millimeters
thick, with a wrinkled epitheca below.

Surface spinuloso-granulose, raised in irregular low monticules, with a

Intertubular spaces more or less elevated above the small projecting lips
of the tube orifices, making the surface appear as if covered by expanded
polygonal openings, as in the former species. Tubules one-filth to one-
fourth of a millimeter wide.

This species has much resemblance to Fistulipora spinulifera, but it does not
grow in massive ramifications ; its laminar expansions are more delicate,
while, on the contrary, its surface has a coarser texture.

Locality. Shore of Lake Erie, near Hamburg. Shales of the Hamilton
group.

Fistulipora utriculus nov. spec.

Strumose branching utricules, or irregular cysts, with a dermatic crust
covering the inner cavity. Large cellulose maculae dispersed over the sur-
face. Tubules one-sixth of a millimeter wide. Intertubular spaces and
maculae spinuloso-granulose. Orifices generally surrounded by a shallow
depression, from which the tube margin projects under the form of a sharp
lip. Distance of orifices about one tube diameter, excepting the cellulose
maculae. The three last-mentioned species are very similar to each other,
but, aside of the different manner of growth, each one has some constant
smaller peculiarities, which convince me of their specific difference.

Locality. Widder, C. W., in the upper strata of the Hamilton group.

Fistulipora crassa nov. sp.

Digitato-ramose, or undulated explanate masses, attached to other bodies or
partially free, with a concentrically-wrinkled epitheca on the lower side.
Surface raised in obtuse monticules, with more or less extended cellulose
maculae on the summits.

Tubules one-third to nearly one-half a millimeter wide, distant from each
other one or a little more than one tube diameter, excepting the before-men-
tioned maculas.

Orifices rotundate, slightly sinuate, surrounded by an unequally-elevated
margin, which exhibits sometimes two dent-like projections into the tube
cavity.

Tube diaphragms distant, or not developed. Intertubular tissue coarse.
Opercula of usual form, sometimes noticeable.

Locality. Widder, C. W., in the lower strata of the Hamilton group, and in
the drift deposits of Michigan.

Fistulipora elegans nov. spec.

Thin laminae, with a concentrically-wrinkled epitheca below.

Tubules one-third of a millimeter wide, prostrate at the base, rectangular
to the surface at the upper end. Orifices perfectly circular, with an equally-
projecting, crenulated rim distributed over the surface at a distance of about
one tube diameter, excepting the cellulose macula, which, however, are not
very conspicuous. Opercules very frequently preserved, flat, with a central
opening, which in some is closed by a subsequently deposited globular solid
stopper. In a few specimens, I see six elevated ridges radiate from the inner
opening to the outer circumference, exactly as in the opercules of Callopora
elegans. Intertubular cell-mass coarse, with angular cells as large as the

of every interstitial cell perforated by a minute opening.

Locality. Shore of Lake Erie, Hamburg. Widder, C. W., in the Hamilton
group.

The carboniferous limestone encloses, likewise, a number of interesting
representatives of the genus.

Fistclipora Spergenensis nov. sp.

Undulated convexo-concave laminae, or strumose utricules and cyst, with
an epitheca on the inner or inferior side Tubules one-third of a millimeter
wide, distant less than their own diameter. Orifices circular, surrounded by
an elevated rim, which projects more on the outer side. Many specimens
have no elevated tube margins, and exhibit interstitial spaces with open cells ;
but this is only owing to an imperfect state of preservation, or the effect of
detrition. Surface raised in obtuse unequal monticules, with cellulose
maculae in the centre.

Locality. Spergen Hill, Ind. Warsaw Limestone.

Fistclipora flabellum.

It is fixed to the ground by a prevalently-cellulose, thick basal expansion,
consisting of concentrically superimposed layers. From this base, elevates
itself a compressed, more or less elongated stem, which finally expands in a
thin fan-like double leaf, fissible in two folia, with a dermatic crust on the
inner face of each. This division in two laminae goes through the whole
stem, to the bottom of the basal attachment.

Tubules prostrate at first, and then bending rectangular to the surface.
Width one- fifth to one-fourth of a millimeter. Distance of tubules more
than one tube diameter, arranged in subregular rows, which are much inter-
rupted by large, not elevated cellulose maculae. No diaphragms observed.
Orifices rounded or obtusely triangular, with a projecting lip, but more fre-
quently not elevated above the surface, and without a lip. Intertubular
spaces, if in good preservation, decorated with fine flexuose anastomosing
striae. Cell tissue usually appearing solid homogeneous, but in some better
preserved specimens, of distinctly vesiculous structure, as in other Fistuli-
poras. In some specimens, the orifices are closed by slightly depressed
opercula with a small opening.

Locality. Spergen Hill. Warsaw Limestone.

This species shows, by its mode of growth, a strong affinity to the gronp,
which includes Ptylodictya, Stictopora, Phaenopora, Clathropora, etc., which
all do, in elementary structure, correspond with Fistulipora, being composed
of tubules of the same configuration, and of an intertubular cellulose tissue.
I find it strange, that no one describing these different-mentioned genera
has stated the cellulose nature of this intertubular substance, although it
forms an important and essential part of all these bryozoa.

Fistclipora trifolia nov. spec.

From an incrusting basal expansion of prevalently-cellulose nature, tri-
angular stems about one centimeter wide, with sharp eVlges and concave
sides, grow up. From the surface of these, new three-edged folds elevate
themselves, and prolongate into stems, whereby a very peculiar sort of rami-
fication is produced. Each triangular stem is composed of three leaves,
grown together with their inner sides, forming a three-edged central suture
line, from which the tubules begin in a prostrate position, but soon become
rectangular to the surface of their respective leaves.

Surface generally appearing worn, with not projecting round orifices one-
fifth of a millimeter wide. In perfect specimens they are surrounded by an
elevated rim. Distance of orifices about two tube diameters. Intertubular
spaces where not worn, exhibiting the elevated angular outlines of the cells.

FlSTDLIPORA COMPRESSA nOV. Spec.

Occurs associated with the former.

It grows in compressed ramose stems about one centimeter wide in the
larger diameter, which are fixed to the ground or to foreign bodies by an
irregular basal expansion. Surface raised in obtuse, unequal monticules,
with a cellulose macula in the centre of each. Tubes one-sixth of a milli-
meter wide, of irregular form, distant about a tube diameter or less, and, if
the surface is not worn, surrounded by an elevated margin. Structure in
conformity with all the other Fistuliporas.

Fistclipora peculiaris nov. spec.

Is a very interesting representative of stellate or floriform tube orifices in
Fistulipora, with whose occurrence in the genera Chaetetes and Collopora we
have already become acquainted. It grows in thin leaf- like expansious, with
orifices on both sides, or in simple leaves with an epitheca below. Orifices
circular, surrounded by an equally-projecting margin, distant more than their
own diameter, and exhibiting from six to ten tooth like projections from their
inner circumference. By grinding away the superficial portions, the tubules
appear still provided with these radial dents, an evidence that they are not
gpinulose projections confined to the tube margins, but the euds of vertical
ridges, running through the whole length of the tubules.

The surface is dotted with scarcely-elevated cellulose macuhc, which, like
the narrower intertubular spaces, are finely granulose. Intertubular tissue
vesiculose. Tubules rarely septate.

Two specimens.
Ctenosaura pectinata Wiegmann, Herpetologia Mexicana. Cyclura, Durn.
and Bibr.

Numerous specimens of this large Iguana ; one taken with its mouth full
of the flowers of a papilionaceous tree called Sabi. The Iguanae are known to
be herbivorous, and CHinther has stated that the Basilisci are likewise. I can
add the Cyclura baeolopha, and many A n ol e s , not only the large, but
the small species. The latter take also ants, as described by G-osse and Wood.
The separated plates of the muzzle, with the small scales between them, place
the Metopocerus cornutus Wagl. of the West Indies between this genus and
the true Cycluras. The latter species was taken by Weiuland in Hayti (Mus.
Compar. Zoolog.) and by Fr. Klett in Navassa, southwest from Hayti. (Mus.
Academy.)

Ctenosaura acanthura Wiegmann. Herp. Mexicana.
Apparently not so abundant as the last.

Cachryx defensor, sp. et. gen. nov.

Digits shortened. Body compressed. Nostril on canthus rostralis, lateral.
Femoral pores, no preanals. Tail short, flat, covered with verticils of strong,
erect, conic spinous seales. Head covered with small uniform scales ; no
interparietal. A strong gular dermal fold. No dorsal crest.

This genus is allied to Urocentrum and Hoplurus, but differs in the pos-
session of femoral pores. It agrees in this with the depressed genus Hoplo-
cercus Fitzinger, but in it the caudal scales, though partially spiny, are not
whorled. Euphryne Bd. resembles it, but in it the scales of the whorls are
not prolonged into spines, and the animal is depressed.

Head at posterior margin of orbits equal length from end of muzzle to
middle of frontal region. Scales on muzzle larger than others. Loreal region
concave ; nostril in hinder part of a single scale. Ear large as eye, without
marginal serrations. Scales of body small, slightly imbricate, homogeneous,
smooth, in transverse series, and oblique longitudinal ; larger on the rump,
smaller on the sides : a slightly larger vertebral series. Abdominals smooth,
equal dorsals ; gulars a little smaller, equal on plica. A prebrachial and
postauricular fold. Scales of fore limb moderate, some of those of femur and
tibia much larger, spiniferous. Caudal whorls fifteen, the scales below nar-
rowed, keeled, the carina prolonged into a flat spine. Spiniferous superior
whorls seven, spines nearly erect, those of the median row smaller. With
hind limb extended, the longest digit does not reach the axilla. Femoral
pores six to nine. Bright olivaceous ; shoulder and two bands on humerus,
and the anterior part of dorsum, with interscapular region, black, the latter
with two cross series of green spots, more or less distinct on the whole body
in younger specimens. In older specimens, median dorsal region bright
rufous.

Total length, 8 in. 6 lines. Muzzle to gular fold, 1 in. 7-5 1. ; to vent, 5 in.
Fore limb, 2 in. 15 1. Exped. Coll., Nor585.

This remarkable genus is decidedly iguaniform, but the digits are too short
for an arboreal habit. Its tail is like that of the most spinous Ctenosaura,
halved, and excessively abbreviated.

Sceloporus serrifer, sp. nov.

A stout species, near the S. spinosus, but differing in its fewer and
larger scales, with more serrate margins, and in its coloration. It belongs
therefore to the section with large lateral scales and only one row of large
supraorbitals. In this species the latter are bounded by a complete series of
inner and outer marginals. Scales from nape to rump, in twenty-three cross
series, each with a long mucro, and two and three lesser ones on each side of
it. Interparietal broader than long ; frontal narrow, only transversely divided,

posterior portion very small. Internasal longer than broad, elevated, some-
times sharply keeled. Lores deeply grooved. Claws of extended hind limb
nearly to ear ; femoral pores 9 — 10. Auricular marginal scales tbin, not so
large as those just preceding. Median abdominal scales once, gulars twice
or thrice emarginate. Tail rather short. Length from end of muzzle to vent,
4 in. 1 1.

Color above greyish or brighter green, with a complete pea-green bordered
black collar, which is narrower on the gular region. Throat and sides of <^
blue, the latter broadly black-bordered behind and medially. A yellow bar
across prefontals, one between orbits and one across occiput, all separated by
brown or blackish, the posterior green-bordered behind. Younger specimens
have the back brown cross banded. Nos. 734, 719.

Sceloporus chrysostictus, sp. nov.

Near the S. scalaris, but without auricular marginal scales larger
than the temporal, with smaller dorsal scales and different coloration.
Lateral and ventral scales nearly equal ; dorsals in forty-five rows from occi-
put to rump, obtusely mucronate, not notched. No larger plates behind
parietals. Cephalic plates rugose ; three pair supranasals ; internasal small,
flat ; frontal nearly equally transversely divided, anterior half longitudinally
divided. Interparietal narrowed anteriorly, long as broad ; parietals oblique,
longer than broad. Supraorbitals surrounded by marginals, the external
separated from them by a row of rhombic scales. Unguis of extended hind
limb to near nostril. From end of muzzle to vent, 2 in. 2 lines.

Brown, with two golden longitudinal lines from above ear to above groin,
separated by nine rows of scales. A series of short, indistinct reddish brown
cross-bars on each side the dorsum within these lines. Sides darker, with
golden spangles ; axilla and scapular region black. Head dark brown ; below
pale brown, chin darker.

complete preocular. It differs from the two known species of its genus in
having smooth scales. An upper preocular, on one side exceedingly minute,
neither attaining the frontals ; a loreal extensively margining orbit, on one
side divided by a horizontal suture. Postoculars three, inferior in contact
with fifth and sixth labials, superior with occipital only. Superior labials
nine, three posterior longer than high ; inferior eleven, fifth and sixtli minute
and bordered by two hexagonal shields within ; (one side mutilated.) Inter-
nasals and prefrontals broader than long, frontal broad as long, lateral longer

nate on the caudal region, in thirty-three longitudinal rows ; head elongate,
with three or two loreals, one preocular and two or three postoculars. Maxil-
lary teeth weak, slightly longer in front. Vertex and front plane, muzzle
narrow, rounded, rostral not prominent. Nasals elongate, internasals a little
broader tlian long, prefrontals long as broad. Preocular not quite reaching
frontal ; latter longer than broad, front and sides straight, forming rectangles,
posterior angle very open. Temporals three, long, oblique upwards and back-
wards from the sixth upper labial, separated from occipital by two small scales.
Nine superior labials, all longer than high, fourth and fifth under orbit. Pre-
geneials long, postgeneials rudimental. Tail a little less than one-fifth total
length. Gastrostega 266 ; anal divided; urostega 118.

Yellowish gray, with fifty jet black, white margined dorsal spots, which
occupy thirteen scales transversely and three and four longitudinally. They
are narrower and more approximated posteriorly, and are accompanied by a
series of similar quadrate lateral spots alternating with them: light brown
irregular spots on the ends of the gastrostega. Below immaculate. A narrow
and broad black crossband on the muzzle, latter from orbits ; one on each
side from the superciliary shield to the nape, and a median band from middle
of frontal to beyond occipitals, enclosing a pale occipital spot.

This species is said to be common in the Belize, " where it is called Clap and
riawyer." It grows to eight or nine feet in length, and is very active in its
movements.

This is an anomalous species of the genus ; its elongate form, loreals, and
general physiognomy approximate it to the Dipsadine genus Trimorphodon,
of the same region.

+ Pttyw/jt from the severance of the nasals.

[May,

NATURAL SCIENCES OF PHILADELPHIA. 129

The genus is near to Carphophis inmost respects, including the divided anal
shield, but differs in its two distinct nasals, of which the anterior is pierced
for the nostril. There are two postoculars, and fifteen series of scales. Teeth
equal. Form rather slender. The postgeneials are quite small, and con-
verted into scales similar to those at the extremities of the gular gastrosteges :
they nevertheless occupy the true position of geneials. The pregeneials are
very large, and so wide as to reduce the two sm ill inferior labials bordering
them anteriorly, to a longitudinal linear form ; they crowd the first pair into
a transverse linear series : the symphyseal is very small and transverse.
Seven inferior labials, fourth and fifth much largest. Superior labials seven,
of which the last and fifth are large, the lattter not quite reaching superior
postocular, the sixth lower : temporals 1 — 1. Occipitals elongate, frontal
broader than long, prefrontals several times as long as internasals, largely
margining orbits. Rostral not projecting ; nasals two, nostril in anterior,
which nearly reaches labial bonier ; loreal long, bounded by second, and
chiefly third superior labial. Pupil round. Gastrosteges 135, anal divided,
urosteges 36. Length of head and body, 10 in. ; of tail, 2 in. 2 1.

Color above glossy dark brown, the centres of the scales paler, of the outer
row especially, reducing the dark to mere margins. A darker brown line
from nape to tail on the filth series on each side. A darker shade on hinder
part of occipitals and end of muzzle. Straw colored below, extending on su-
perior labials round margin of rostral : tail brown below, except middles of
proximal ^cutella.

In this species the pupil is round.

Siphonops sy ntremus sp. nov.

This species differs from the four hitherto known, in the close approxima-
tion of the narial and tentacular openings : the latter lie a little behind the-
former, and are slightly larger. The minute eves are just visible ; the inter-
nal nares are some distance behind the palatine arch. Muzzle projecting, ob-
tuse in profile; from above narrowed, rounded. Teeth large, five on each
ramus mandibuli. A gular, and strong postgular fold ; 130 annular pli.se,
which are complete, except slight ventral interruption anteriorly ; the poste-
rior third of the length with intermediate annuli, which are first lateral only,
then complete above, entirely complete on the terminal inch : the whole num-
ber will then be about 170 annuli.

Form of body rather slender; tail depressed at end. short, acuminate.

Color dark plumbeous, annuli yellow lined ; head yellowish brown.

This species resembles the ('oevilia ochrocephala, but is primarily dis-
tinguished by the position of the foramen, and of the inner nares, also by the
color and character of annuli.

The species of the genus now are, S. i n d i s t i n c t u s, R. & L. , S. a n n u-
latus Mikan, S. brasiliensis Liitk., S. mexicanus Dum., Bibr.,
and S. syntremus m.

Ranula chrysoprasina sp. nov.

In examining a collection sent to the Smithsonian Institution from Arriba,
CustaRica, from Chas. N. Itiotte, I was much surprised to notice what was appa-
rently a Hylorana near H. erytbraa. Doubting the correctness of the
locality, I laid it away. Having since seen other and allied species from
Tropical America, I recognize the existence of a genus representing Hylorana,
but differing in the important particular of the incompleteness of the ethmoid
arch, its superior plate being represented byoartilage. In the present species
the terminal phalanges are slender, and furnished with a transverse limb,
though the dilatations are small ; the latter are distinct in the Rana coeru-
leopunotata Steindachner ; in an undescribed species from Vera Paz the
the transverse limb is very small, but present.

Ethmoid arch superiorly cartilaginous ; prefrontals narrow, longitudinal
widely, separated. Distal phalanges slender, with transverse limb ; no meta-
tarsal shovel ; tongue bifurcate.

The species is allied to the last, but has a relatively shorter muzzle and
limbs. Nostril nearer end of muzzle than orbit (equidistant in coeruleo-
punctata); muzzle 1 1-5 th orbit (1 2-5th Steind.) Under jaw anteriorly
abruptly truncate. Canthus rostralis straight, strong, muzzle acuminate from
its extremity, projecting ; loreal region vertical. Tympanum elliptic two-
thirds orbit. Vomerine teeth weak, in convergent fasciculi behind opposite
nares. Skin shagreened above, a glandular fold on each side. The longest
linger cannot be extended to vent ; heel to middle loreal region. Toes fully
not widely palmate, three distal phalanges of fourth free ; one minute meta-
tarsal tubercle.

Color brilliant leek green, the groin and belly approaching golden ; a golden
band from lip to shoulder, and faint one on each side back. Limbs above,

Steindaehner represents much less palmation than exists in our specimen.

It is interesting to observe how that this Raniform type, while preserving
its definitive features in this outlying region of its distribution, and within
the limits of the lower fauna? of South America and Australia, offers the low-
est condition of cranial structure consistent with this type, i. e., the imperfec-
tion of its ethmoid and prefrontal bones.

Golostethus latinasus gen. nov.

By this name I propose to characterize a genus of Ranida?, the type of which
.is the Phyllobates latinasus m., Pro<\ Acad. Nat. Sci. 1863, 48.

The sternum is Raniform without manubrium, and with membranous
xiphisternum, quite as in the Bufoniform genus Dendrobates, from which the
presence of very well developed teeth only separates it. It will form a Group
I. of Fam., Ranidas before that occupying that place in System Batrachia Sa-
lientia, Nat. History Review, 1865, and tending towards Bufoniformia. The
characters are —

Group I. No manubrium, xiphisternum membranous. External meta-
tarsi bound ; distal phalanges with terminal transverse limb.

Character of genus. Digits free with dilatations ; no vomtrine teeth ; pre-
frontals widely separated by the largely produced bony superior ethmoid
plate.

Phyllobates ridens sp. nov.

The close areolation of the ablomen, throat, and lower face of femora, the
recurved angle of the mouth, the minute (one-eighth orbit) tympanum above
the ordinary position, and truncate tongue, are marked features in this species.
The tongue is broad and extensively free, and each angle behind is thickened.
Choans small, Eustachian ostia minute. Skin smooth, without folds or tu-

and subtransverse opposite it : toes slightly webbed. Width between tym-
panic regions nearly double the length from muzzle to nuchal fold. Muzzle
prominent, as long as orbit, nostrils nearly terminal. Mandible with two
symphyseal notches, and median knob. Tongue flat, elongate ; slits of vocal
vesicle large. Heel to front of scapula.

Critical Review of the Family PROCELLARIIDiE :— Part IV ; Embracing the
JESTRELATE-E and the PRIONEiE.

BY DR. ELLIOTT COUES, U. S. A.

In the present paper, the fourth of the series, are together considered the
jEstrelatea and the Frionece, mainly for the purpose of showing how closely
related these sections are through certain of their genera.

For the first of these sections three names are at our disposal ; sc. sEstreJa-
tece, Daptionece and Rhantistece. Of these I prefer to accept the first, both as
having priority, and being taken from the name of the typical and largest
genus of the group ; the second being based upon a subtypical genus with but
a single species, and the third being derived from Bonaparte's erroneous
identification of Kaup's Fulmaiine genus Rhantistes.

The section JEstrelatecB, as here restricted, corresponds very nearly with Ihe
group defined under this name in Bonaparte's Conspectus. There is here,
however, included in it the genus Daption*, by Bonaparte placed among the
Fulmarea ; and it is considered as probably connecting the ^-Estrelatei.e with
the Prions. The genus Thalassoica is excluded as being essentially Fulma-
riue. In generic arrangement I am compelled to differ widely from the dis-
tinguished author just named. After attentive and critical examination of his
genera C»okilaria, Pterodroma and Buhverla, I must confess my inability to
distinguish either of them from ^-Estrelata by a degree of morphological dif-
ference which, by any sublimation of characterization, can be considered of
generic import. " Bulweria " has a rather more elongated and deciledly
cuneiform tail than have the majority of the iEstrelatas ; but differs from
some of them in this respect, no more than they do among themselves.
" Pterodroma" comprises some fuliginous species morphologically identical
with jEstrelata. " Cookilaria " has no characters whatever assigned to it by
its author ; possibly because none are to be found in the species included
under it.

I do not hesitate to follow natural data afforded by specimens, even should
they conflict with the opinions of so justly distinguished an author as that of
the " Conspectus ; " especially since the more closely I scrutin'ze his work
upon the Petrels, the more irresistibly the conviction is forced upon me, that
it is, to speak in the mildest terms, unreliable. It cannot be denied by the
most strenuous of his advocates, that there are to be found in this work in-
stances of unnecesssary if not unwarrantable pseudo-generic subdivisions ; of
some pure figments in the way of species ; of rash collocation of synonymy ;
and of weak and intangible diagnoses. These are to the last degree discoura-
ging, because perplexing, to the student. — crede mihi experto. They would,
however, be less repellant, and bear much more weight, could we feel satisfied
that they represented the matured opinions of the author, based upon well-
digested facts. Such unhappily is not the case ; for the views expressed on
different occasions are found to fluctuate according to the particular theory
which may have been in posse sion of his mind at the time of writing; and
are often diametrically opposed to each other. That I may not seem to wan-
tonly criticise one of the most brilliant lights that has ever shed its radiance
upon Ornithology, to whom alas ! it was not permitted to finish his last great
work, I may be allowed to sustain myself by a simple comparison of the
"Conspectus" with the Table of the Longipennines published in the Comp-
tes Rendus. The fasciculi of the former which treat of the Petrels bear date
of Dec, 1855, and Jan., lS5(i ; the latter is of the seance of April 28, 1856. I
only cite some of the more glaring discrepancies of generic arrangement and
distribution of species ; for concerning synonyma it may be stated that as a
general rule conflicting views are entertained on all debatable points.

" The true relationship of this genus is still with me a matter of some uncertainty.

tributed thus : — tijpus (here called cinerea Gm.) is put under Prioflnus,*

are put under JEstrelata of the " Rhantisteo3.,,

Rhantistes ex Kaupf taken, with Coolcii Gray, velox Sol. mollis, "unicolor,'"
" raolensis " Gould, and Lessoni Garnot as determined species ; rostrata, par-
virostris Peale, gelida Gm. and sandaliata Sol. as doubtful species.

C. A. Genus JEstrelata contains diabolica L'Herm. (syn. haesitata Temm.

Forst. (—Lessoni Garnot.) — C. R. The same genus is made to contain diabolica
L'Herm. hcesitata Temm. (here considered distinct from diabolica,) sericea
Less, flavirostris Gould, desolata Lath. ; with gularis and brevipes Peale, and
inexpectata Forst. as doubtful species.

C. A. Genus Nectris Bp. emend, ex Forst. contains brevicauda Brandt, car-
neipes Gould, fuliginosus Strickl. gama Bp. and tenuirostris Temm. — C. R.
Nectris abandoned, and its species thus distributed : brevicaudu? and carneipes
are put with cincrevs Gm. under Prioflnus H. & J. ; fuliginosa Strickl. is
made a queried synonym of Puffinus major Faber ; gama Bp. does not appear:
while tenuirostris is united with sphenurus, etc., under thegen'is Thiellus.

However great the changes and innovations thus introduced, — which are
indeed " une foule des faits nouveaux relatifs a la classification, a la nomen-
clature, a la synonymie. et aux divers rapports des espcces," resulting " de
leur etude appiofondie "J between Dec. 1855 and April 1856, I am unwilling
to believe that the " Table" is drawn up with reference to the size and shape
of the Comptes Rendus page, rather than in accordance with truth.

The numerous difficulties which beset us in the critical investigation cf any
group of the Petrels, reach their maximum in the section now under considera-
tion. This is in a measure due to the habitat of most of the species — the
genera being essentially South Pacific and Antarctic in their distribution — which
renders the acquisition of specimens difficult, at least in such numbers as to
enable extended comparisons to be instituted, and the great changes of plu-
mage which a majority of the species undergo with increasing age, to be fully
and accurately elucidated. Some are to this day known only by type speci-
mens ; while of many others we are no more familiar regarding variable
features of coloration, than to enable us to speak in the most general terms of
the changes undergone during progress towards maturity. But these are
among the minor evils to be contended with ; for Nature herself is perhaps
never so difficult of comprehension, as we often find our attempts to under-
stand her to be. And so the confounding of distinct species under one name
and description ; the making of nominal ones out of changes of plumage and
variations in size ; together with the misinterpretation by writers of the labors

*Tliis is an important correction. '• Prioflnus cinereus" is the proper name of the species called
in the C. A. "Adamastor ti/pus."
t This name of Kaup's is a synonym of Fulmarus Leach.

of their predecessors, have produced a bibliography so embrouilUe as to defy
our most patient efforts to completely unravel the entangled skein, and to
cause us to turn with weariness if not disgust from the hopeless task. The
necessity which exists for the study — I use the word advisedly — of synonyma,
is the opprobrium of ornithology ; and the kind of labor demanded for their
elucidation is far removed from the real pursuit of science itself. At the same
time, while an inevitab'e, it is too often a thankless labor, and one hardly ap-
preciated ; the results of which are usually incommensurate with the time
and trouble expended. Collocation of synonyma is by no means mere clerical
compilation. It is a species of investigation which, to be productive of any
value, demands a sound judgment and powers of discrimination perhaps of
as high a grade as those required for the successful study of genera and spe-
cies. But it does not often bring to its author such rewards as are willingly
granted him who elucidates other classes of facts in Natural History. For as
i's chief duty is to deal with disputed points, it enters an arena where more
conspicuously figure not facts but rather opinions ; concerning which the
right of arbitration is yielded by no man to another, The synonymist must
ordinarily expect acquiescence with his views from those only whose ideas are
not jostled by the opinions he advances.

It is impossible to pursue a critical investigation of the Procellariidce with-
out being impressed by these facts ; which must be my only weapon wherewith
to turn the edge of criticism from my efforts towards the elucidation of the
family. No one can be more painfully aware of the errors of omission and
doubtless also of commission, which must be met within these papers; and
none can be less tenacious of debatable views, or more ready to relinquish
opinions when proof of their fallacy is made apparent. I only ask a thorough
examination before a condemnatory fiat is passed upon any of the views enter-
tained which may be at variance with current opinions.

As a rule I have adopted for species no name to which any doubt as to
identity attaches ; while those still open to discussion I have endeavored to
treat of solely with reference to their intrinsic merits, no extraneous claims to
our consideration being acknowledged. I regret the necessity of frequent
citations of manuscript names and unpublished drawings, which we are by no
means bound to recognize; but which have become so interwoven with the
bibliography of the family, that it is impossible to avoid so doing.

The present paper, like others of mine, is doubtless amenable to the charge
of " discursivene s." This fault, if it be one, is certainly of that class which
"lean to virtue's side ; " and one which at present I feel indisposed to cor-
rect. Words are cheap enough ; and bad they not been so parsimoniously
doled out in the earlier days of ornithology, there would now be less need of
a nrofuse expenditure of them.

The sEstrelatese, as I regard them, are composed of three genera, which may
be briefly diagnosticated as follows : —

A. Tail much graduated, or cuneiform.

I. Bill robust, compressed, the unguis large, and curved
from the nostrils. Extension of feathers on forehead

normal. Hallux small. Nostrils short JEstrelata.

B. Tail slightly rounded.

II. Bill stout, compressed, unguis large, nostrils short.
Forehead low, flat, the feathers encroaching far on the
b 11. Interramal space feathered. Hallux large and

stout Pagodroma.

III. Bill greatly dilated. Nostrils long. Feathers on
forehead normal in extension. Unguis small and weak.
Interramal space partially naked. Hallux ordinary... Daption.

Color also affords us an excellent artificial index to these genera. Thus
. Estrelata is bicolor or fuliginous ; Pagodroma is unicolor, white ; and Daption
is spotted with light and dark colors.

The first of these genera, after the fusion with it of those of Bonaparte
already adverted to, is quite an extensive one, comprising more species than
any other of the family. In this paper I enumerate eighteen, which appear
to have just claim to recognition. At the same time some of them, as I iuti-
mate, may not be valid, while I am quite willing to believe that there may
exist good species of which no cognizance is here taken.

Chs. — Bill about as long as the tarsus; very stout; compressed; higher
than broad throughout; lateral outlines nearly straight, converging to the
much compressed unguis. Unguis particularly large, strong, its upper out-
line very convex, its tip greatly decurved ; arising almost immediately from
the end of the nasal tubes, leaving but a very brief and quite concave culmen
proper. Lateral element of the bill very strong ; rising high up at the root of
the nasal case ; somewhat inflated throughout ; and with a strongly convex
inferior border ; which with the great decurvature of the unguis produces an
extremely sinuate commissure'; outline of lower mandible nearly straight ; of
gonys a little concave ; eminentia symphysis well marked. Sulci on both
upper and under mandibles distinct. Nasal tubes of moderate length, eleva-
ted, conspicuous, not carinated, dorsal outline about straight, apex more or
less vertically truncated, orifice subcircular, each naris oval, separated from
its fellow by a thin vertical portion which comes well forward. Interramal
space narrow, fully feathered. Wings comparatively longer than in most
sections, surpassing the tail when folded ; pointed ; but the second primary
nearly as long as the first. Tail long, and much graduated ; sometimes almost
cuneate, usually much rounded ; the rectrices quite broad to their tips. Feet
of moderate size ; tarsus moderately compressed, with the ordinary small
subhexagonal reticulations; about as long as or a little less than the middle
toe without its claw. Outer toe rather surpassing the middle ; with its claw
about equalling the middle and claw. Tip of inner claw reachingbase of middle
one. Hallux short, sessile, conical, acute, elevated. Of moderate and rather
small size ; bicolor, or nearly so ; in youth nearly unicolor.

The genus sEstrelata as thus defined is quite an extensive one, comprising
a larger number of species than any other of the family. In its geographical
distribution, it is essentially southern and antarctic ; only a very few of the
eighteen or more known to compose it being found in north temperate lati-
tudes. The numerous species all agree in certain points which separate them
from others ; the principal of which is the large size and great convexity of
the unguis of the bill : which begins to rise almost immediately from the
nasal case. Other peculiarities will be noted in the above diagnosis ; which
have caused the species to be put in intimate relation to each other when col-
located even by those writers who recognize but one, or at most three or four
genera of Procellariince.

Taking the hxsitata as the type of the genus, we find that most of the
species, — Lessoni, rostrata, etc. agree entirely with it : while some others,
e. g. Cookii, differ in being smaller and more slenderly built, with rather less

138 PROCEEDINGS OF THE ACADEMY OF

robust bills, somewhat longer and more pointed wings, etc. These latter
characters have been made typical of a distinct genus by Bonaparte. The
gradation, however, in these and all other features is so gradual, through
several intermediate forms, that I do not see how we are to draw the dividing
line. Bonaparte moreover includes in CooMlaria such a species as Solandri,
which is particularly a robust bird.

Throwing out of consideration the fuliginous " Pterodromine " group, we
find that the other species of yE<trelata adhere quite closely to a particular pat-
tern of coloration. When adult they are dark colored above, being of some
shade of brown or black, with more or less of an admixture of cinereous, and
generally have a white forehead. The color of the upper parts extends on the
sides of the breast ; otherwise the under parts are wholly white. When
young, the color of the under parts does not diifer very notably as a general
rule from that of the upper: the white being obscured by a dusky, fuliginous
or cinereous clouding of the tips of all the feathers, the basal portions of which
remain white. In general the younger the bird the more uniform, or more
tending towards fuliginous are its colors: while in adult life light and dark
colors occupy distinct areas, and are quite trenchantly defined.

When we consider, therefore, the great change which the plumage under-
goes in the bird's progress towards maturity, together with the similarity
that exists between corresponding ages, it will not appear surprising that not
only very numerous nominal species should have arisen, but that names of
species should have been frequently misapplied to others than those to which
they rightly belong ; producing a confusion in the synonymy certainly not
surpassed, if indeed equalled, in any other penus in ornithology. A number
of the species were first brought into notice by voyagers ; and when named by
professed naturalists it was at a time when the neces-ity of detailed descrip-
tions was not appreciated, so that the nice points of size and proportion which
really distinguish the species more than colorj were rarely presented. The
consequence is that it is now impossible to identify many of the older names
with any degree of certainty, except perhaps by incidental or collateral testi-
mony ; and to this day a great many identifications remain matters of opinion
rather than of fact.

Nor is the confusion and uncertainty by any means less in the fuliginous
group which goes to compose this genus. Its components, so far as we know,
are in every age unicolor ; and are absolutely indistinguishable except by
form and dimensions. This alone would have been amply sufficient for the
production of synomyms and malideutifications innumerable ; but this inevi-
table result is furthered by another fact. The " genus " Pterodruma is among
the JEstrelatea exactly what Nectris is among the Pajfinetv ; i. e. composed of
species differing in no wise in form from ^Ettrelata or Puffinus, and which are
entirely fuliginous in color. Now the points of form separating the species of
" Pterodroma " from " Nectris " are by no means patent on a casual examina-
tion ; and hence, among the older writers we find many descriptions which
it is impossible to refer with any degree of certainty to one or the other genus,
of which, in short, we can say no more than that a fuliginous petrel formed
the subject of the article. Consequently, some synonyms have ever been oscil-
lating as to weight of authority between these two groups.

I confess to a feeling of surprise, when, on examining critically species
typical of Bonaparte's genus Pterodroma, I could find absolutely no points of
form whereby it might be held separable from ^Estrela'a. I do not think that
the skeleton will be found to present any tangible morphological characters,
critically examined in its minutest details of intermaxillary bone or phalanges ;
nor do the remiges or rectrices in their relative developments offer the
slightest discrepancies. We mu*t have recourse therefore to color alone if we
would separate them ; aud Bonaparte himself gives us no other character

NATURAL SCIENCES OF PHILADELPHIA. 139

whereby we may recognize his genus. I am therefore constrained to unite
the so-called genus with sEstrelata.*

This fuliginous section, then, of jEstrelata, comprehends some four or five
species, very widely distributed, as regards latitude ; though, so far as we now
know, cliierly occurring in the tropical and temperate portions of the Atlantic.
A new species from Jamaica is being published as I write. f

With the exception perhaps of A. Bulweri, these are only distinguishable by
size and some points of coloration of the feet.

This latter species differs from the type of " Pterodroma " in the somewhat
more elongated and decidedly cuneiform tail, which is hardly contained twice
in the wing from the carpal joint ; and perhaps in having comparatively
slightly smaller feet. The difference iu the tail is no greater than that existing
among unquestioned species of ^Estrelata : and in all other points there is an
absolute identity of form. This species is the type of Bonaparte's genus
Bulweria, and by him it is placed among the Thalassidromines ; upon what
grounds I am at a loss to conjecture.;); The "genus" seems to me to bear
exactly the same relation to Fterodroma that Thiellus, Grloger, (as defined by
Bonaparte to include sphenurus Gould, and chlororhynchus Lesson), does to
Nectris.

The genus Cookilaria, founded by Bonaparte upon the Pr. Coolcii, Gray, has
not evm an apology for characters whereon to base claims to recognition. A
diagnosis is not attempted by its author ; aud a few weeks subsequently the
name is dropped ; § and Rhantistes \\ substituted, although the species collo-
cated under the latter designation are by no means the same as those pre-
viously included in Cookilaria.

The other partial synonyms quoted at the head of this article are merely
instances of the reference to them of some of the species included in the genus
as it is here defined and limited. Of the several names at our disposal,
JEstrelata has, so far as I can ascertain, the priority. The species given in
the following pages include all I have been able to learn of, through specimens
or books, as having just claims to recognition. Very possibly some valid ones
.are omitted ; and perhaps some now retained may hereafter help to swell the
list of synonyms ; that wearisome and vexatious, but inevitable, mass of rub-
bish, repelling inquiry, and retarding progress, under the burden of which
ornithology now labors.

* This procedure may stem inconsistent with the course followed in a previous paper of mine
upon the Puffins:. It is there, however, explicitly stated that the difference between Nectris or
Thiellus, and Puffirms, is scarcely aucht than that of color, and that these genera " are hardly
worth retaining, except it be for convenience's sake." (Page 117 : and see also pp. 122, 12S. 142.
143.) Tire recognition of genera founded upon fuliginous color in this family is perhaps peculiarly
to be deprecated ; since some species are known to pass from a fuliginous unicolor to a bicolor
state of plumage with increasing age; and moreover, it is by no means incontrovertibly proven
that some supposed fuliginous species are not merely immature plumages of others. I most
willingly relinquish the position above referred to ; and am now indisposed to degrade, eveu upon
a plea of utility, so harmonious a group as every natural genus forms.

Procellaria ruhritarsi, Gould, (nomen ined. supprimend.)

Habitat. — Atlantic ocean, coasts of America and Europe. The most boreal
of the bicolor species of the genus, and the only one hitherto detected on our
shores.

Form.* — The bill is about as long as the tarsus ; much shorter than the
skull ; longer than the middle toe ; very stout ; but slightly higher than broad
at the base ; moderately compressed in the rest of its extent. The lateral
lamina is very strong and large, a little inflated, short, very deep at the base.
The unguis is large and strong, and its convexity begins almost from the end
of the nasal case, leaving but a very brief and very concave culmen proper.
The commissure is extremely sinuate, having several different curves. The
unguis of the lower mandible is also strong, its point a little decurved, the
gonys convex, the angle at the symphysis acute but not very prominent. The
sulcus on the sideof the inferior mandibular ramus is distinctly marked. The
nasal case is in length about a fourth of the culmen ; broad, depressed, scarcely
carinate ; the orifice large, subcircular ; apex a little obliquely truncated ; each
naris oval, with a distinct septum which reaches to the end of the case. The
frontal feathers overlap the base of the bill, and descend in a nearly straight
line on the sides ; thence rapidly retreating backwards. The feathers on the
side of the lower mandible extend much further than to a point perpendicu-
larly beneath the furthest extension of those on the upper. The interramal
space is fully feathered.

The folded wings reach a little beyond the end of the tail ; the first primary
is longest ; the second nearly equal ; the rest rapidly graduated.

The tail is very long, being contained scarcely more than twice in the
length of the wing from the carpal joint. It is very cuneate in shape ; the
central feathers sometimes even projecting slightly beyond the rest. The
difference between the median and outer pair of rectrices is fully one and
a half inches.

The tarsi are moderately stout, and very regularly reticulated with small
sub-hexaeonal plates ; largest on its interior aspect. In length it about equals
the middle toe without the claw. The outer toe is a little longer than the
middle ; but the claw of the latter is so much longer than that of the former,
as to make the tips of the two about equal to each other. The tip ot the inner
claw just reaches the base of the middle one. The latter is a little dilated
on its inner aspect. Hallux of the usual shape.

Color. — On the crown of fully adult birds there is a vertical central area or
" calotte " of blackish brown. The more mature the bird, the smaller is this
spot, and the more trenchantly are its edges defined against the white which
surrounds it on all sides. But in young or immature birds, — in fact, in the
majority of all the specimens we examine, —this perspicuous definition of the
dark area is interfered with in this wise : on the front many of the feathers
are brownish black, producing a spotted or variegated appearance ; and the
same dark color, usually somewhat diluted in tint, extends from the crown on
to the occiput, nape, and even adown the back of the neck, until it may
coalesce with the color of the back. On the sides of the crown the dark color
may be generally distributed, merging into the transocular fascia of dark color
which always exists. This latter band of color which passes through the eye
is in adult birds well defined, and quite distinct from the calotte. Iu all ages
and plumages it is somewhat darker in tint than the crown itself.

compared Mr. Lawrence's type of Procellaria meridionalis.

NATURAL SCIENCES OF PHILADELPHIA. 141

These simple facts regarding the varying extension of the dark colors of
the head and neck, in a species which otherwise is not known to differ
materially in plumage, have given rise to descriptions so worded as to be ap-
parently quite in conflict with each other.

Back a nearly uniform clear bistre brown : but most of the feathers often
have slightly lighter margins of an ashen hue. The shade of brown of the
back deepens on the wings and wing coverts into blackish brown ; which
is especially intense in color on the outer webs of the primaries ; their inner
vanes being fuliginous brown.

The distal half of the tail is like the wings in color : the basal half is white,
except the outer web of the exterior feather, and to a less extent some portions
of the outer webs of the two next ones. A few of the shortest, most anterior
upper tail coverts are colored like the back ; the rest are white. On the sides
of the flanks a few feathers are touched with brown.

The upper tail coverts ; the forehead, lores, sides of head, neck,* under wing
coverts, (except the row just along the edge of the wing), axillars and whole
under parts are white.

Bill black ; iris brown ; tarsus, first joint of toes, and contained portion of
webs flesh-colored ;t rest of webs and toes, with claws and hallux, black.

In the young bird, the colors generally are rather darker, and tending more
strongly towards smoky brown ; but I have never seen a specimen entirely
dark-colored below, though such a state of plumage may be found. The bead
and neck all around, and upper part of the breast, may be concolor with the
back, as described under the young Lessoni.

Dimensions. Bill (chord of culmen) 1*45. Nasal tubes -33, (a little more
or less). Height of bill at base '68 ; width *60 ; depth at greatest convexity
of unguis -60. Wing (average) 12*00 ; tail 5-50 to 5-75. Tarsus 1-45 : outer
toe ami claw 2,12; middle do., the same; inner 1*75. Gradation of tail
about 1-50.

The subject of the present article bears an intimate resemblance to no other
species of Petrel ; and, on this account, it is the more surprising that its
synonymy should have become so involved as it will be evideut is the <ase
from the succeeding remarks on its bibliography ; and, particularly, it has no
sort of resemblance to the Adamastor cinereus, to which its name of hcesitata has
been so often misapplied. Moreover, the species, so far as we know, is not
subject to as great changes of plumage as many others of the genus ; its gene-
ral aspect, as regards color, is not that of the other congeneric species, but
rather of Pvffinus major ; and why, therefore, its synonymy is so involved is
a difficult matter to conjecture.

Bibliography. The first definite reference to this species which I have found
is the Proc. hcesitata of Kuhl, as above cited. The description given by this
author is entirely pertinent, both as to colors and dimensions ; in fact, some
expressions quite exclude any other species. Dr. Kuhl also speaks of his
specimen as being "in musaao Bullockiano, nunc in Temminckiano," so that,
very probably — though I can by no means speak with certainty — his bird was
the very individual which furnished the subject for PI. Col. 416 of Temminck ;
an accurate figure now universally referred to as representing this species.

At the outset we thus have a very definite starting-point iu discussing the
synonyms of this species ; but, most unfortunately, Dr. Kuhl adduces as syn-
onyms of his hcesitata two refen-ncesj to Forster's unpublished drawings, and
cites Forster as authority for the species. Whereas, neither of these draw-
ings refer to the bird now under discussion ; and the first published use of the

rely upon Mr. Newton's authority.

name hcesita'a by Forster was to indicate a very different bird ;* not an JRstre-
lata at all, but one of the Piijfinew. These unfortunate citations have ever
since been the cause of a sort of double employ of the name by ornitholo-
gists. The synonyms at the head of this article, taken in connection with
those given under Adamastor cinereus, (Pr. A. N. S., 1864, p. 119,) contain
most of the references of consequence which bear on the question.

One must not fail to consult in this connection Mr. A. Newton's very
thorough and lucid exposition of the bibliography, as well as an accurate
description, of this species, given in the "Zoologist,'' as above cited, on the
occasion of the first introduction of the bird into the British Avifauna. Some
very important corrections and verifications are there presented.

The name hcesitata Forst. had been long in existence, in manuscript, for a
species very different from the present; but being first published, (in 1820,
when we first gained the right of recognizing it,) by Dr. Kuhl, for the
species now under consideration, it must necessarily stand in this connection.
I do not see, therefore, why Bonaparte supersedes it by di"bolica of L'Her-
minier. This latter quotation, as well as the reference to a Puffinns VHer-
minieri of Lesson, I present on the authority of Bonaparte, not having the
opportunity of verifying them personally. The name " rubritarsi " of Mr.
<*ould is to be suppressed as unpublished by him, and, moreover, as con-
veying an erroneous impression regarding the color of the feet.

The htesitata of L-sson's Traite, p. 611, is this species; but the author
erroneously cites hcesitata Forst. and leucocephnla Forst. as synonyms.

I have before me the type specimen of Procellaria meridional is, kindly
transmitted to me for examination by Mr. Lawrence. It is an example of
JEstrelata hcesitata. ; as, indeed, Mr. Lawrence himself suspects may be the
case. (B. N. Amer., text of p. 827.) Any differences which may exist in
the specimen in question, from the figure given by Mr. Newton in the Zoolo-
gist, seem rather accidental than real. This same individual had been for-
merly called " brevirostris " by Mr. Lawrence — a name preoccupied by M.
Lesson for a fuliginous species of " Pterodroma." Mr. Lawrence enumerates
with entire accuracy the synonyms of this species under head of Proc. meri-
dionalis, in the Birds of North America, p. 827. The name hcesitata, as em-
ployed by Mr. Lawrence, and also by Mr. Gould, refers to the Adamastor
cinereus, and not to the present species.

I have not met with any names or descriptions published during the
eighteenth century which are definitely reterrible to this species ; and, if
there be any other synonyms than those above commented upon, they have
not been brought sufficiently into notice to r quire recognition in this con-
nection. The chief point is to be able to decide, without hesitation, to what
hozsitata, as used by different authors, really refers. t

Habitat. — South Pacific and Indian Oceans.

Form.* Bill much shorter than the skull, but slightly less than the tarsus,
about two-thirds the middle toe and claw ; very robust, as broad as high at
the base, compressed in the rest of its extent. Unguis of upper mandible
very large, strong, deep, convex, much decurved, the tip acute ; the elevation
of the unguis beginning so near the nasal tubes as to leave but a short and
very concave extent of culmen proper. Lateral lamina? large, strong, wide,
inflated, deep at the base ; superior margin nearly straight, running obliquely
downwards and forwards from the frontal feathers to the commissural edge of
the unguis ; its lower margin sharp, a little inflected, very convex in outline.
The commissure is not very sinuate from the angle of the gape to the unguis.
The under mandible has a very distinct and deep lateral sulcus, which is
widened at both ends. The inferior unguis is large and strong, its tip much
decurved and acute, its gonys very concave, its angle at the symphysis pro-
minent but not acute. The outline of the inferior mandibular rami is a little
concave ; the interramal space is feathered nearly to the symphysis. The
nasal tubes are short, broad, somewhat depressed, their outline nearly
straight and ascending a little from base to apex ; the latter obliquely trun-
cated and emar^inated. The frontal feathers overlap the culmen, nearly in a
straight line or with a slightly convex outline ; thence immediately retreating
gradually backwards as they descend the sides of the bill. Those on the
lower mandible do not extend further than a point perpendicularly below
those on the culmen.

The wing is of the ordinary length and shape. The tail is comparatively a
little shorter and less graduated than in hasitata, and is contained a little
more than twice in the wing from the carpal joint.

The tibia? are feathered to within half an inch of the joint. The tarsi are
short, about three-fifths the middle toe and claw, moderately stout, but little
compres-ed, with the usual small subhexagonal reticulations. The tip of the
inner claw just reaches the base of the middle one. Uuter toe longer than
the middle ; but the tip of its claw does not quite reach to the tip of the
middle one. Claws all long slender, little curved, acute, compressed, the
middle one somewhat dilated on its inner edge. Hallux short, slender,
straight, acute, conical, sessile.

Color. Bill pure intense black. Tarsi, and basal half or more of the toes
and webs flesh -colored ; yellowish when dried. Rest of toes and webs, in-
cluding the whole aspect of the outer toe, blackish.

The head all around and the whole under parts are pure white. But a well-
defined bar of slaty or cinereous black passes through the eye. The upper
tail coverts and superior surface of the tail are clouded with light grayish
rinereous. On the nape the white of the head begins to be shaded with
pearly gray which deepens as it descends adown the back of the neck on the
interscapulars and dorsal parts generally into grayish slate ; which a^ain
lightens on the rump. This color varies much as to intensity or dilution ;
but is never as dark as the wings. Both surfaces of the wings are deep slaty
black: the greater coverts inclining to dark slaty gray: the under surface
rather duller in color than the upper ; the prevailing color changing gradually

into dull brownish gray on the edges of the inner webs of the primaries.
Some of the under wing coverts are edged and tipped with grayish white. A
few of the Ion? axillars are chiefly white with their terminal portions slaty.

The preceding description is taken from a specimen from the South Indian
Ocean, mentioned by Mr. Cassin in the Proceedings, as above cited. The fol-
lowing is from one of the specimens taken by Mr. Peale, one of the natural-
ists of the United States Exploring Expedition under Ci>m. Wilkes. The
specimen in question is labelled in Mr. Cassin's hand-writing "P. Lesso?}ii
Garnot:" and while absolutely identical in form with the species as usually
known and recognized presents the following exceedingly different colors : —

Young. No. 15709, Smiths. Register. Terra del Fuego, T. R. Peale.
Entire upper parts dusky fuliginous brown ; the dorsal feathers usually
with somewhat light margins ; the color deepening on the wings and tail into
brownish black. Some of the secondaries, tertials and upper coverts have a
slight cinereous tinge. On the head and nape the brown is lighter than else-
where ; and a somewhat diluted shade of this color extends adown the throat,
thus completely enveloping the head : and occupies likewise the upper half
of the breast, quite across, as well as all the sides under the win us. On the
crissum, and especially on all the under tail coverts except immediately
around the anus, the color again deepens into brownish black. The rest ot
the under parts are white. The circumocular region is darker than the
adjacent parts.

The foregoing is the most immature plumage known to me, and it will be
noticed that not only the colors themselves, but the pattern of coloration is
radically distinct from those of the adults. In some specimens is recogniz-
able a faint shade of a darker color on the tips of the feathers of the other-
wise white under parts ; whence I infer that in very young birds the whole
under parts may be brownish or grayish.

Dimensions. Chord of culmen 1-50; width or height at base *60 ; nasal
tubes -25 ; from feathers on side of lower mandible to its tip 115 ; along
rictus 2-0~>. Tarsus 1'65 ; middle toe and claw 2-50 ; outer do. 2'40 ; inner
do. 2-10. Wing 11-50 to 12 00. Tail 5"00 to 5'50. Graduation of lateral
feathers rather more than an inch.

Synonyma. Amoug the older authors, I only find one name — alba, of
Gmeliu and Latham — which seems at all referrible to this sp"cies. P. alba is
evidently an yEslrelata, of about the size of Lesioni, and the colors as
described apply tolerably well to a somewhat immature example of this spe-
cies. But there is nothing in the diagnoses of either of these authors which
absolutely restricts the name to the P. Lessoni ; and, therefore, in the uncer-
tainty, I would by no means supersede M. Garuot's appellation Lessoni, the
description of which is quite pertinent. I believe Mr. Cassin, in the Proceed-
ings of the Philadelphia Academy, as above, was the first to refer the bird to
its proper genus.

The Procellaria leucocephala of Forster is certainly this species. His
description is in every respect pertinent to the adult bird. Although the
name had been used, in manuscript, as applied to Drawing No. 98, for many
years, it was not published until 1844, and, consequently is antedated by
Lessoni of Garnot, (ls26). Forster's editor, Dr. Lichtenstein, says, probably
correctly, that leucocephala Forst. is the alba Gin. ; but certainly incorrectly
that "vix nisi setate differre videtur a Proc. hcesitata Forst. ;" whereas hcesi-
tata Forst. is not even congeneric with leuc cephala.

I am unable to discuss the synonyms variegata, Bonnserte, and vagahunda
Solander, which I quote on the authority of Bonaparte.

Habitat.— Tahiti. (Peale.)

The following detailed description of this little known and hardly recognized
species is taken from Mr. Peale's type specimen, now before me.

Form. — The bill is much shorter than the head or tarsus, about two-thirds
the middle toe without its claw ; exceedingly robust, especially at the base
where it is as high as broad, and where its height is nearly equal to half the
length of the culmeu. The lateral lamina? of the upper mandible are very
wide and large ; especially basally, where their upper margins rise so high as
to be nearly on a level with the dorsum of the nasal case, the tubes being
thus almost buried between the lamiuse. In consequence of this shape of the
lateral laminae the sulcus is extremely sinuate, extending from the top of the
root of the nasal case to the commissural edge of the unguis, near its middle.
The inferior edge of the laminae, forming in great part the cutting edge of the
upper mandible, is decidedly convex in outline. The unguis is large and
strong, and its elevation, which begins almost directly from the termination
of the nasal case, as well as its convexity and decurvation, are very great.
The under mandible is straight, its sulcus strongly pronounced, its tip de-
curved and acute, its unguis large, its gonys quite concave, though there is
but a slight protuberance at the symphysis.

The nasal tube is short, wide, depres ed, turgid, not carinated, convex in-
outline both antero-posteriorly and transversely ; its apex obliquely truncated,
broad, depressed, not emarginated, the nares circular, separated from each
other by a rather thick septum which comes forward to the very end of the
nasal case. The frontal feathers encroach far upon the dorsum of the tubes,
with a rounded termination, and then slope gradually backwards and down-
wards.* The feathers on the sides of the lower mandible do not extend to a
point perpendicularly below the apex of the frontal feathers.

The wings are long, the first primary considerably surpassing the second ;
and when folded they reach considerably beyond the end of the tail. The
latter is of moderate length, contained rather more than twice in the length
of the wing from the carpus ; and it is much graduated in shape.

The feet are comparatively large for the size of the bird, absolutely about
equalling those of Lessoni, which is a larger bird. The relative proportions
of the tarsus and toes are much the same as in other species. The hallux is
rather long, slender and acute.

Dimensions. — Length about 14 inches, "extent 39-50," (Peale.) Wing 11 ;
tail 4-75 ; bill along chord of culmen l-37 ; heighth or width at base '66 ; nasal
tubes "25 ; from feathers on side of lower mandible to its tip 1-20. Tarsus
1*75 ; middle toe and claw 2-25, outer do. 2-12 ; inner do. 1*80; hallux '25.
From apex of longest secondary to tip of longest primary in the closed wing
3-25.

Color. — Entire upper parts pure deep blackish brown, including the under
surfaces of the wings and tail feathers ; everywhere of a nearly uniform tint ;
but a little darkest on the outer webs and tips of the primaries, and somewhat
lighter on their inner webs, especially towards their bases. This color of the
upper parts extends around the sides of the head, neck and breast ; but be-
comes on the chin, throat and breast a little paler; and includes the sides
under the wings, and crissum. Kest of under parts, including the under tail
coverts, pure white ; the latter however have a few isolated brownish streaks.
The line of demarcation between the dark and light colors on the breast is not
very trenchant. The bill is black. The tarsi are pale yellow ; probably flesh
colored in life. A small space on the lower part of their external aspect, and
the whole toes and webs (except a small yellow spot on the inner web near
its base) are black.

This color of the upper parts is a pure very dark brown, with no mixture

vrhatever of ashen, gray or plumbeous. The distribution of colors is almost
exactly that of the species of Cataractes.

1 do not think that the plumage above given is that of the adult ; it so
closely resembles that of the immature j*E. Lessoni, which is its nearest ally.
It is the only one, however, of which we have at present any knowledge.

I think it most probable that this is a valid species. There is none to which
it bears any very intimate resemblance, except Al. incerta and ^E. Lessoni.
The relationships of the former will be noticed elsewhere. Compared with a
young yE. Lessoni, in which the size and pattern of coloration are not widely
diverse, I find them to differ as follows : The upper parts of rostrata are of a
deeper, purer brown. The under tail coverts are almost wholly white; those
of Lessoni wholly dark colored except immediately about the anus. Rostrata
is a smaller bird, the wing being an inch, the tail rather more than an inch
shorter ; but the feet are absolutely of the same size, and therefore compara-
tively larger. The bills of the two birds are nearly of the same length ; but
the radical difference in the character of the nasal tubes, the degree of tur-
gidity of the base, and the outline of the feathers, as will be evident on coin-
paring the descriptions given, at once distinguish them.

It is quite possible that some of the indications of older authors may have
reference to this species ; but in the utter impossibility of establishing any
such with certainty I think it best to assign no synonym whatever.

Habitat. — Honden Island.

As in the case of ^E. rostrata I describe this supposed species from Mr.
Peale's type specimen.

Form. — Bill much shorter than the head, but very little less than the tarsus,
about two-thirds the middle toe ; slender, compressed, considerably higher
than broad at the base ; its lateral outline about straight. Nasal tubes much
as in mollis.* A considerable concavity of culmen between the nares and the
. elevation of the unguis ; which latter does not rise very high, but is neverthe-
less very convex ; much decurved, attenuated and hooked. Sulcus on side of
the upper mandible curved, its convexity looking downwards, and greatest
near the base of the bill, where the lateral laminae rise high up to embrace
the roots of the nasal case. Commissural edge of upper mandible strongly
>inuated. Lower mandible almost exactly as in mollis ; perhaps a trifle slen-
derer. Outline of feathers on base of bill just as in mollis.

The wings are exceedingly long, when folded much surpassing the tail.
- First and second primaries about equal and longest. Tail of moderate length,
contained about '2>\ times in the wing. It is greatly graduated, the difference
between the external and median rectrices being 1*25 inches.

The tibia? are denuded for nearly half an inch. The plates on both sides of
the tarsus are small, irregular and very numerous. The tarsus is a little
more than three-fourths as long as the middle toe and claw. The usual pro-
portionate lengths of the toes prevail. The claws are all small, weak and
little curved. The hallux is minute, straight, not very acute.

Dimensions. — "Fourteen inches long, by 36 in extent," (Peale.) Wing 11 ;
tail 4*50 ; tarsus 1*25 ; bill 1*08 ; outer toe and claw 1-66. From tip of longest
secondaries to end of primaries 4-25. Gradation of tail 1'25.

Colors. — Entire upper parts, including both surfaces of the wings and tail,
deep fuliginous brown, (with no trace of ashy or plumbeous) becoming almost
black on the outer webs of the primaries, and inclining to grayish fuliginous

on their inner webs and towards their bases. The head, neck and breast all
round are like the back, but not quite so intense in color ; and the dark tint
only occupies the extreme tips of the feathers ; while its continuity is also in-
terrupted by some whitish spots that show at intervals. There is no distinct
line of demarcation between the dark color of the breast, and the pure white
which occupies every other portion of the under parts of the bird, with the
exception of a few dark brown isolated feathers along the sides under the
wings and the crissum, and some streaks on the outer margins of the external
under tail coverts. The bill is black ; the tarsi, first digital phalanges, and
included portions of iuterdigital membranes, are dull yellowish, but were
probably flesh colored in life. The rest of the webs and toes are black.

The above is a copy of Dr. Schlegel's description of this s apposed species, of
which the author further says: " I have not been able to refer this species
to any one hitherto described. It appears allied to the Proc rostrata, Peale,
* * but has the under tail coverts dark colored instead of white, and its
colors generally are less brownish." It is to be deplored, that in introducing
a species into so difficult a family as the present one, a more detailed descrip-
tion was not given.

As well as I can judge by the description, the species is about the size of I'.
rostrata, but distinguished from the latter by the different color of the under
tail coverts, and a less decidedly brown tinge of the upper parts generally.
It is probable also that if the bill possessed the turgidity which characterizes
that of rostrata, together with the peculiar outline of the frontal feathers,
these points would not have escaped the attention of Dr. Schlegel. The bird
may pretty safely, then, be separated from rostrata.

I think that it is to the immature plumage of yEstrelata Lessoni that the
species is to be referred, if it be really not valid. There were no recognized
specimens of this latter species in the Museum of the Pays-Bas when incerta
was founded. It comes in all respects exceedingly near the plumage I des-
cribe above as that of the young Lessoni ; so much so that I fail to detect ma-
terial discrepancies. Still I should not like to reduce any species founded by
a competent naturalist, except by autopsy ; and therefore leave it as described
by its author; only desiring to call attention to the necessity of careful com-
parison with the plumage of the young Lessoni.

I can offer no opinion concerning this supposed species, except to state that

it may possibly be, as Dr. Schlegel himself seems inclined to suspect, the

^Estrelata parvirostris. But this latter species itself is so very near mollis

Gould, that it may hereafter prove to be only a state of plumage of the latter.

"Total length 16 inches; bill 1^; wing 12; tail 5| ; tarsi £; middle

The preceding is a copy of Mr. Gould's description of this species. This
author further says of it. "This is a remarkably robust and compact bird.

1 shot a single individual in Bass' Straits, on the 13th of March 1839. M.
Natterer thought that it might possibly be identical with the bird figured in
Banks' drawings, and to which Dr. Solander has affixed the term melanopus,
an opinion in which I cannot concur. I have accordingly named it in honor
of that celebrated botanist. The specimen above described may possibly
prove to be not fully adult, as the dark coloring of the under surface only
occupies the extreme tips of the feathers — the basal portions of which are
snow-white."

I have not enjoyed an opportunity of examining a specimen of this species,
and none, so far as I am aware, are contained in any American collection. It
appears to be exceed;ngly distinct from any other species of sEttrelata, if not
in colors at least in proportions of bill and feet, as compared with the abso-
lute size of the bird. The dimensions of these parts as given by Mr. Gould, —
particularly the shortness of the tarsi, as compared with the lengths of the
toes, are quite different from that of any other species of the genus ; so much
so that the bird may not be a true sEstrelata ; upon which point however I
cannot now give a definite opinion. The type of the species is doubtless, as
Mr. Gould surm'ses, not fully adult ; and when mature the dark coloring of
the under parts will in all probability disappear, leaving the whole inferior
regions of the body white. The unicolor pattern of the feet is diverse from
the ordinary style which prevails in nearly all the species of the genus.

By Bonaparte the species is referred to his "genus " Cookilaria, though
for what reason is not obvious, since Mr. Gould particularly notes that his
species is a " remarkably robust and compact bird," while the type of
"Cookilaria" is the leucoptcra Gould; almost the very smallest and most
gracefully formed species of JEilrelata. Dr. Schlegel's identification of So-
landri with grisea of Kuhl is elsewhere commented upon.

This is a species of Latham's which has not so far as I am aware been identithd by later

conclusion regarding it. it is. however, in all probability some species of iV. rt.ris, of the l'ttffinetu :
fo that we need not therefore be prevented trom using Kuhl's came of grisea for a bird of the

The preceding description is compiled from the diagnosis of a species given
by Dr. Schlegel (as above cited) from the Australian seas. That writer iden-
tifies it with the grisea of Kuhl, and gives Solandri of Gould as a synonym.
I am unacquainted, autoptically, with any species differing from mollis Gould,
by the characters as sjiven by Dr. Schlegel. That gentleman, however, has a
specimen indicating such a species, and upon the competent authority of the
accomplished Director of the Pays-Bas Museum, I recognize the species as dis-
tinct from mollis. The color of the plumage I do not think can be regarded
as a constant and valid character, since some ages of mollis present exactly
the tints described as those of grisea. The species must therefore be separa-
ted, if at all, by the more compressed bill, different colors of the feet, and dif-
ferent proportions of some of the parts. Taking Dr. Schlegel's description and
specimen as the only tangible basis on which the supposed species I am now
treating of rests, there are presented for our consideration the following points
of synonymy.

Attentive study of Kuhl's description of the bird he calls " grisea L.," and
examination of his figure (fig. 9) will show clearly that it is by no means the
species described by Latham under the name of "Gray Petrel, P. grisea."
Latham gives the bill as two inches long, while Kuhl's figure delineates a bill
measuring just one inch along the chord of the culmen. Other discrepancies
are palpable throughout. Latham's grisea appears to be a Nectris, while
Kuhl's is an ^Estrelata very near mollis. Kuhl himself takes occasion to note
some descrepancies between his bird and Latham's.* Kuhl's expressions
" rostro valde compresso ; * * corpore et tectricibus alarum inferiori-
bus ciuerascente fuliginosis, pedibus pallidis " together with his measure-
ments, are entirely pertinent to the bird whose characters are given by Dr.
Schlegel ; so that the only question is the distinctness of the species from
molhs.

While I thus entirely agree with Dr. Schlegel in this identification of Kuhl's
name, I can by no means assent to the referring of Mr. Gould's P. Solandri to
this species. P. Solandri is certainly radically distinct ; and so different in
its proportions that I cannot understand how Dr. Schlegel could have recon-
ciled it with P. grisea.

Dr. Kuhl (1. c.) says of the P. lugens of Forster (ic. 21) that he considers it the
same as grisea ; he also adduces P. lugens Banks, (tab. 21 and 22,) as a syno-
nym of the latter. My quotation of these names is entirely upon Dr. Kuhl's
authority.

The jEstrelata inexpectata of Bonaparte's Conspectus evidently belongs here
rather than to the true mollis. The author quotes Kuhl's grisea as a synonym ;
and the diagnosis he gives presents nothing incompatible with the present
species. The true inexpectata of Forster is, I think, mollis, as I attempt else-
where to demonstrate.

As a summary of the preceding remarks I may state that if there be a spe-

those characters laid down by Dr. Schlegel, and of which the specimen in the
Museum of the Pays-Bas is an example, then the synonyms adduced at the
head of this article are most properly to be referred to this species ; but other-
wise they must be considered as appertaining to mollis.

Form.% Bill as long or slightly less than the tarsus, nearly equal to the
middle toe without its claw ; compressed, a little higher than broad at the
base. In the details of its shape it does- not differ from the typical species of
JEstrelata. The proportions of tarsus and toes are also as in other species of
the genus. The tail is only moderately rounded, instead of being decidedly
cuneate with some projection of the median rectrices, as in jE. haisitata ; its
length is contained in that of the wing from the carpal joint slightly more
than twice. The folded wings reach considerably beyond the tail. The spe-
cies in size and general contour of the body approaches Daption capensis.

I do not notice that the plumage is softer, fuller, or more mollipilose than
iu some other species of the genus.

Color. There is a transocular black fascia, the greater part of. which lies
below the eye. The clear ashy gray of the upper parts extends over the ver-
tex, becoming more or less mixed with white on the front and cheeks, accord-
ing to age. Most of the feathers of the back have slightly paler margins. The
primaries are nearly concolor in all their extent ; (compare description of No.
15,706 Smithsonian Collection, infra ;) being only a little duller or more fuli-
ginous on their inner webs. The under surface of the wing is chiefly dusky
brownish ; but there is an illy-defined and interrupted area of whitish, par-
ticularly towards the bases of the primaries. The upper tail coverts and tail
are chiefly concolor with the back ; but some of the outer rectrices are marbled
with white.

In the majority of specimens the color of the back extends on the sides of
the breast for a considerable distance; sometimes quite across the middle:
hut in very adult birds most of the breast is pure white. The color is pro-
duced by a clouding of the tips only of the feathers, their basal portions be-

iug white ; and often is not uniform in tint, but is minutely undulated or
punctulated with lighter and darker shades.

The front, lores, lower part of cheeks, and whole under parts, including the
lower tail coverts, are white. The lateral rectrices are on their inferior aspect
chiefly white, with some light cinereous marbling.

In general terms it may be stated that the older the bird, the clearer and
purer is the cinereous, and the more trenchantly defiued are the boundaries
of the several differently colored areas ; the difference in this respect being
especially notable in the forehead and sides of the breast.

Young birds are all over of a pretty uniform deep brownish ash, or fuligin-
ous cinereous ; inclining to smoky brown on the wings and tail. The whole
under parts are not notably different from the back, though, however, the
dark color only occupies the tips of the feathers ; their basal moiety remain-
ing white. The transocular dark fascia is always present. But the chin and
face are much mottled with whitish ; and in specimens otherwise wholly dark
on the under parts, the chin aud throat may be chiefly white, striatulated
with ashy brown.

Moulting specimens, or those in poor plumage from the age and worn con-
dition of the feathers, show scarcely a trace of cinereous on the wings and
tail, these parts being of a dull brownish, more or less tending to gray. The
same tendency to brownish or grayish instead of cinereous is observable on
other parts. Sometimes a pure white chin and throat coexists with complete
dusky clouding of the other under parts.*

The bill and feet hardly differ in color with age. The bill is black; the
tarsus, basal half of inner toe and contained web, flesh colored : (dull yellow-
ish when dry ;) all the rest of the toes and webs, with all the claws, black.

Dimensions. (No. 1678, Phila. Acad., J. Gould.) Bill (chord of culmen)
1-10. Height at base -45 ; width slightly less. Tarsus 1-33. Outer toe and
clawl'75; middle about the same, inner 1*50. Wing average 1O00 ; but
may range from 9-50 to 10-50 ; tail4"50 ; the graduation of the rectrices about
1'30. These are nearly the average dimensions of six examples.

There is a specimen, No. 15,706, in the Smithsonian Museum from the
Antarctic Ocean, by Mr. T. R. Peale, which, with the size and general appear-
ance of mollis differs as follows : The under surfaces of the wings are, except just
along the edges, purely and uninterruptedly white ; as much so as in C okii.
The inner vanes of all the primaries, instead of being simply duller and grayer
than the outer, have trenchantly defined pure white areas ; these white spaces
occupy the whole of the webs at the base ; as they extend more towards the
apex they become less wide, leaving a narrow space of dark color along the
inside of the shafts ; apically they terminate with an acutely pointed outline,
which stretches towards the tip of the feather, and is bounded internally and
externally by dark colored portions of the feather. The general pattern is
exactly that seen in the primaries of most Lari ; and the definition of the two
colored areas is as strict. In other respects the bird is like a quite young
mollis, being dark colored both above and below ; but the tint of the cloud-
ing below is more intensely sooty than in any specimen of typical mollis I have
9een ; and there is this peculiarity in addition, that the under tail coverts
remain pure white.

I do not wish to introduce a new name upon the above basis ; though pos-
sibly in any other family than the very one of the Petrels I would do so. The
points which would consiitute its specific characters are elucidated in the pre-
ceding paragraph ; and should the differences above pointed out be substan-
tiated as persistent in other specimens, it would, I think, then be proper for
the ornithologist who makes the verification to forma ly introduce the species.
The specimen in question before me is the only one contained in the United

States Wilkes' Exploring Expedition collection ; and is, therefore, in all
probability, the very individual upon which Mr. Peale based his description
of gularis ; which name should, therefore, stand for the species, in the event
of its proving valid ; even though Peale's description does not notice the
peculiar markings of the primaries.

Bibliography. It is possible that the P. melanopus of Gmelin and Latham
was based upon this species. Their bird evidently was an JEstrela/a, and
"thirteen inches long;'' and the description of the colors would apply pretty
well to an immature mollis. But mollis has a bill by no means an inch and a
half long ; and is not found, so far as we know, " circa Americani septen-
trionalis." The only known North American species of ^Eslrelata is the
hcesitata ; of which the bill is nearly of the length stated by Latham. Under
the circumstances, I do not think this name is to be adopted for ei her species.

I think there can be no doubt that the inexpectata of Forster is really this
species. I find no points of the description, nor any of the measurements, at
all incompatible with this supposition. Dr. Lichtenstein refers inexpectata to
grisea of Gmelin ; certainly incorrectly, whatever may be its relations to
grisea of Kuhl.

The name mollis Gould bears the same date of publication as inexpectata,
(1844) : so that it is difficult to say which actually has priority. I think, if
any choice is allowed us, we should, by all means, use mollis, so definitely
characterized and well known. Mr. Gould, in describing the species, says
that it had been identified with lugens of Banks, and with grisea of Kuhl (nee
Gm.) This may very possibly be the case ; although, for the present, I give
grisea Kuhl, (of which lugens Banks is a synonym,) as a distinct species,
for reasons stated elsewhere.

In the Ibis, as above, Mr. G. R. Gray has a species P. Phillipii from Norfolk
Island; based upon the "Norfolk Island Petrel," Phill. Hot. Bay, p. 161 ;
with P. alba, var. Lath., and P. mollis Gould, as synonyms, the latter queried.
No description is given, and I merely follow Gray himself, in placing the
name as a queried synonym of mollis. Vieillot, (Nouv. Diet., xxvi. 1S17, p.
420,) refers to this same "Norfolk Island Petrel."

tuberance at the symphysis acute, if not very prominent. The commissure
is, as usual, very sinuate. The nasal case is contained nearly four times in
the length of the culmen ; broad, depressed, its dorsal outline straight, its
apex very obliquely truncated, its orifice subcircular, each naris oval ; the
septum of considerable thickness, and coming forward to the very end of the
ease. The frontal feathers do not extend at all forward on the base of the
culmen, but embrace the sides of the bill as extensively as they do its b.ise
above ; and thence they slope very rapidly backwards, making a considerable
angle just above the edge of the commissure.

The wings are sufficiently elongated to extend, when folded, a little beyond
the end of the tail, which is, itself, rather longer than in most species of this
group. The second primary is nearly as long as the first ; the rtst are
rapidly graduated.

1 he tail is so long as to be only contained exactly twice in the length of
the wing from the carpus, and the graduation of the lateral feathers is about
as great as in hcesitata, (greater than in mollis,) though the median pair of
rectrices are not specially produced. The upper tail covirts fall far short of
the end of the tail : the under ones reach quite to it.

The legs are short and slender ; the tibiae bare for but a very brief space.
The tarsi are considerably shorter than the middle toe without its claw, and
about equal to the inner ; quite slender, moderately compressed, with the
ordinary rectifications. The tip of the inner lateral claw just reaches the
base of the middle one. The middle and outer toes are of equal length, but
the claw of the latter is much shorter than that of the former : which last is
but very slightly dilated on its inner edge. All the claws are small, slender
and weak, but still much curved and acute. The hallux is of the ordinary
size and shape.

Dimensions. Chord of culmen 1-00; height of bill at base -35 to *40.
Length of nasal case "25. Wing 8-50 to 9-00 ; the distance from end of
longest secondary to tip of first primary in the folded wing 2-75. Tail 3-75
to 4-25; graduation 1-00 to 1-50. Tarsus 1-10; outer toe and claw 1-25;
inner do. 1-12, middle do. 1-33. From upper tail coverts to end of
tail 1-40.

Color. Adult. Above blackish cinereous. On the crown of the head and
its sides to a little below and before the eye, and on the nape the color tends
more towards sooty brownish than to cinereous ; but on the neck behind
this color merges insensibly into the quite pure deep cinereous, which occu-
pies the middle dorsal region, the interscapulars, and some of the tertials.
The rump is darker and more like the crown ; the upper tail coverts again
being cinereous, if anything a little lighter than the back — tending to pure
grayish instead of dusky cinereous. The superior surface of the tail is
plumbeous blackish, lightest and most cinereous basally. Inferiorly the tail
is lighter colored than on its upper surface ; the lateral rectrices particularly
being light plumbeous gray, almost whitish basally. The shafts of the
feathers are above brown, below white, except at their extremities. The
superior wing coverts and all the primaries and secondaries are brownish or
fuliginous black ; deepest along the edges of the wings, and outer borders
and tips of the quill feathers. The inner vanes of the primaries are light
grayish fuliginous, becoming grayish white towards their bases ; but the
transition is quite gradual. The shafts are black above, brownish beneath.
All the under wing coverts are pure white, except one row, the smallest, just
along the edge of the ulna and metacarpus ; producing a broad uninterrupted
white area. On the radial edge of the antibrachium there is a narrow but
well-defined white line:* visible from both upper and under aspects of the

wing. The front, the lores, the sides of the head nearly to the eyes; the
side of the neck, and the whole under plumage, pure white. The color of the
hack almost always, to some degree, clouds the sides of the hreast.

The above is the plumage of a very mature bird. Usually the plumage is
rather as follows. The upper parts generally are less decidedly cinereous —
having more of an admixture of brownish — though the upper tail coverts are
quite notably plumbeous. The forehead is speckled with black : sometimes
the latter color being in excess over the white. The sides of the breast are
very strongly clouded with dark cinereous gray, which may reach quite to
the median line ; though this color is only a wash on the extremities of the
feathers. Some of the feathers on the flanks, and a few of the under tail
uoverts are also lightly touched with plumbeous gray.

Young, The upper parts show scarcely a trace of cinereous anywhere,
except, perhaps, on the upper tail coverts. The front is so much obscured
by dusky that the white only appears in small sparse specks. The whole
under parts are tinged with a plumbeous black hue from the breast back-
wards ; this color being deepest on the breast where it is pure and uninter-
rupted : on other parts appearing as a clouding ©r marbling. The chin and
throat in all the specimens I have seen remain almost pure white, in marked
contrast to the rest of the under parts. The under wing coverts are as de-
scribed in the adult: and the white line along the edge of the fore arm also
exists.

It will be noted that the changes of plumage above described are quite
homologous with those to which mollis is subject.

The bill is black. S mewhat more than half the inner web. and rather less
than half the outer web, together with the tarsus, are light flesh color. The
vest of the toes and webs are black. The colors of the bill and feet seem
subject to little variation with age.

Syrionyma. The name Coolii of Gray has priority by about a year over
leucoptera of Gould ; as, indeed, the latter author himself allows. That
these two names were based upon the same species is not doubted, so far as I
can learn, except by one author. Bonaparte would have it that the bird
figured in plate 51 of the Birds of Australia, and called " Coolii Gray " by
Mr. Gould, is not the species really so named by Mr. Gray ; but another ;
differing slightly in size, though quite identical in color, and for which he
adopts the name relox. In this conclusion, he is quite unsustained by orni-
thologists.

The specimen collected by Mr. T. R. Peale, now before me, which doubtless
is the type of his brevipes of 1848, is an example of this species.

This little species is liable to be confounded with no other, except, perhaps,
the succeeding one ; uuder the head of which latter the apparent differences
are noticed. I find no names of the older writers which seem referrible to
this species ; and its synonymy is less confused than that of most other
components of the genus.

throat, breast, abdomen, crissum and under wing coverts white. Forster's
editor, Dr. Lichtenstein, merely says of it, "inter P. dlbce Lath, varietates

species. An accurate definition of its characters, and an exact exposition of
its relationships, together with its synonyms, if it have any, are greatly to be
desired.

The bird is apparently some small species of yEsfrdata. All the points of
coloration given, especially those of the under wing coverts, are quite con-
sistent wilh the characters of AS. Cookii. But the dimensions as stated are
quite at variance with those presented by Cookii, those of the bill and feet
being much too large, while that of the tail is too small ; these dimensions
being rather those of a small Puffinus. In view of these discrepancies, I pre-
fer to coincide with Mr. Gray's high authority in holding it, for the present
at least, as distinct ; especially as its reference to any described species
would be entirely upon supposition.

This is a species with which I am unacquainted through autopsy. It is
the smallest known component of the genus, being less than the little Cookii.
I have copied Umelin's original indication of the species ; and Dr. Schlegel's
measurements of a typical example, from the Temminckian collection ; the
individual upon which Dr. Kuhl, in ls20, based his description. Both
Gmelin and Latham speak of some portion of the bill as being yellow ; which
was probably an accidental feature in one specimen ; for, as is well known,
all the j^Estrelatas have black bills.

This species is so small, and otherwise so well characterized, that it stands
in the enviable position of having hardly a synonym, although described in
the eighteenth century. I have not met with, or seen anywhere cited, a
single synonym, except that of Bonnserte, above given.

" ? Procellaria lugubris, Tschudi, " according to Bonaparte. Not of Natterer,
which is a Thalassidromine.

Habitat. — Antarctic Oceans. Coast of Africa. (Smith). Van Diemen's
Land. (Gould).

This is a species which I recognize with much doubt. Not having access
to the original description by Smith, 1 cannot speak with certainty regarding
it. It is admitted by Bonaparte, who says of it : " Ex toto fuliginoso-cinerea ;
rostro nigro ; pedibus fiavidis." On the other hand, Dr. Schlegel refers it to
the atlantica ; and the measurements of two specimens in the Pays-Bas
Museum, (one an undoubted atlantica received from Mr. Gould, and the
other a supposed macroptera,) by no means differ in size to a degree incom-
patible with specific identity. If the expression " pedibus flavidis " is cor-
rect, the species would be easily separable. As it is, the only data given by
most authors are the larger size, longer wings, and grayer face, as compared
with atlantica.

It is quite possible that the specimen upon which Dr. Schlegel unites the
two names is not a veritable example of macroptera. Bonaparte evidently
separates macroptera from atlantica on the strength of the difference in the
color of the feet. Mr. Gould says of this species : '' I think that a bird I
killed in the seas off Van Diemen's Land, where it was tolerably abundant,
and which differs from atlantica in being of a larger size, having inuch longer
wings and a grayer face, may be identical with P. macroptera of Smith, and
I therefore retain it under that appellation, in preference to assigning it a
new name." Here is an instance in which an author who, in extensive and
practical knowledge of the Petrels, is surpassed by no other naturalist, deems
the species sufficiently distinct from atlantica. But it is quite possible that
the bird here referred to is not the true macroptera of Smith ; and may likely
enough be an undescribed species of Pterodroma, different from both macrop-
tera and atlantica, as, indeed, Bonaparte hints, (page 191, Conspectus).

On page 611 of Lesson's Traite, ' (1S31,) there is described a Procellaria
brevirostrts, as follows: "Bee noir, court, tres recourbo ; tarses jaune ;
plumage en eutier brun fuligineux ; ailes et queue noir intense. Mus. de
Paris." This is evidently some species of Pterodroma ; and upon this de-
scription, apparently, or, very possibly, upon the specimen itself in the Paris
Museum, Bonaparte has drawn up his diagnosis of the species he calls
"macroptera Smith." I cannot see why he does not employ Lesson's name,
which has priority over mwroptera Smith, provided the two are synonymous.

As a resume of the subject, I may state that I think it quite possible there
are two species confounded in the synonyma at the head of this article. One
is brevirostris Lesson, entirely fuliginous, and with yellow feet. The other is
the species referred to by Mr. Gould, as above, as distinguished from the
common atlantica by its larger size, longer wings, and gray face. Whether
the latter is the true macroptera of Smith remains to be proven. Dr. Schlegel
may be perfectly right in referring the mac r opt era Smith to atlantica Gould ;
and yet the two species I am speaking of may also exist, distinct from each
other and from atlantica.

By Bonaparte the Procellaria lugubris Tschudi* is referred with a query to
this species. As will be seen by the accompanying foot-note, the bird is
evidently some species of Pterodroma ; though the description is so brief
and wanting in measurements that it is impossible to say to which one it is to
be referred, or whether it be really a valid new species.

5-00. Total length 15 to 16 inches.

Fine examples of this well known species are in the Philadelphia Academy,
some of them typical specimens received from Mr. Gould, and labelled by him
" atlantica."

This species is certainly the fuliffinosa of KuhPs monograph (No. 12, pi. x.
fig. 6.) Indeed it is seldom that the descriptions and measurements of the
earlier writers are found so entirely pertinent and readily identifiable as in
the present instance. The figure of the bill agrees exactly. This identifica-
tion is made by both Bonaparte and Schlegel. Although the name fuliffinosa
has been applied by several other authors to different species, none of them
fall in this genus or indeed among the JEstrelalcse. (Examine my synonyma,
mipra.) There would seem to be therefore no good reason why the
•name should not stand for this species, taking precedence over atlantica of
Gould. To Dr. Schlegel is due, I believe, the credit of restoring Dr. Kuhl's
name.

It is quite at variance with the usual great accuracy of Mr. Gould's identifi-
cations, that he should have saidf that this species " i3 the grisea of Kuhl "
(No. 15, fig. 9.) I have endeavored to show, ante&, what I think the grisea of
Kuhl really is; but whether my identification — which is the same as that
made by Dr. Schlegel — be correct or not, Kuhl's grisea is certainly widely
different from the present species.

In ray Review of the Puffinece, page 124 of these Proceedings for 1864, I
maintain the opinion that fuliginosa, Forster, sp. 18, p. 23, of Liehenstein's
edition, is a species of Ncctris; which view 1 am now satisfied is erroneous.
Procellaria fuliginosa Forster is the present species, as maintained by Prof.
Lichtenstein and Prince Bonaparte. Impressed with Kuhl's remark that his
fuliginosa is ''nmnino diversa a Nectri fuliginosa Forst.," I did not discriminate
between this latter name and the Procellaria fuliginosa Forst. p. 23 of Lichen-
stein's edition ; whence my mistake.

I know nothing of the Nectris fuliginosa of Forster, nor do I attempt to iden-
tify Proc. fuliginosa, sp. 27, (;< Banks tab. 23 ") of Dr. Kuhl's monograph. The
latter has recently been identified by Mr. Gray with Proc. pacijica of Latham,
which is some large species of Puffinus (Cat. Birds Pacif. Isl. p. 55.)

In the "Ibis" for 1862, page 245, Mr. G. R. Gray institutes a Procellaria
J'urkinsoni ; which is said to be the bird of Bank's icon. ined. No. 19, and (in
part) the Puffinus icquinoctialis of Gray's list of Anseres of the British Museum,
page 100 , and is compared with xquinoct ialis as follows : " being smaller in all
its proportions; the bill is nearly one-third less than that of sequin octialis ; the

body is sooty black throughout, being without the white on the mentum ; the
tips of the mandibles are inclined to black." This description does not show
well whether the bird is a Majaqueus or a P terodroma ; the comparison with
sequinoctialis would seem to indicate the former; while the citation of Banks'
Drawings No. 19 (by Kuhl placed under his P. fuliginosa — which is the Ptero-
droma atlantica,) would make it a component of the latter group. The habitat
of the supposed species is New Zealand.

blackish fuliginous ; the feet are yellowish, or light colored, passing into black

Habitat. — Atlantic Ocean. Coast of Africa and Europe. Dr. Schlegel has a
specimen from Greenland. Very possibly to be included in the Fauna of North
America.

This interesting species is the smallest of the genus, and quite distinct from
its congeners not only in size but in some of its proportions. It has compara-
tively a longer tail than most species of the genus ; bearing a proportion to the
wing from the carpal joint of 4£ to about 8, or more than half. The tail is
very cuneate, the difference between the median and outer feathers amounting
to 1-75 inches; and the central pair themselves are considerably longer than
the next. The under tail coverts, — at least in the specimen before me, — fall
nearly two inches short of the end of the longest feathers, being in fact no
longer than the upper ones. The folded wings hardly reach to the end of the
tail. The bill is about as long as the tarsus, or the middle toe without its
claw: of the ordinary J^strelatean type ; quite stout at the base, compressed
throughout ; tbe unguis large and rising almost immediately from the nostrils,
and exceedingly convex ; the sulcus on the lower mandible is deep and well
marked; the outline of the rami is nearly straight, the gonys very concave ;
and there is considerable of an emiuentta symphysis. The first primary is
hardly if at all longer than the second. The feet present no special peculiari-
ties in relative size or proportions; the inner toe is perhaps slightly shorter
than ordinary.

The fuliginous color is deepest, being almost black, on the wings and tail ;

dimensions. Chord of culmen 0-85. Tarsus slightly longer, -90 to 1-00 ;
middle toe and claw 1*10; outer do. about the same; inner do. 0-85. Wing
8-00; tail 4-50; graduation of lateral feathers 1-75.

Tbis little species has been very variously arranged in the series by different
authors, as will be seen by the synonyms which head this article. In my
mind there is no doubt that Dr. Schlegel has correctly indicated its affinities
in placing it in intimate relation with, and next after aterrima Verr., albeit he
retains it in his somewhat extensive "genus" Procelluria. My own reasons
for referring it to JEstrelata will be found in my remarks under the head of
that genus.

I am not enabled to state positively what was the first specific name applied
to this species, of the three which head this article. Bonaparte gives prect-
dence to columbina ; but MM. Webb and Berthelot, in giving this name quote
anjinho, Heineken, (1829) as above, which must therefore have been published
anterior to their own appellation columbina. The title page of the work where
the latter name appears, bears the date " 1836 — 44." Dr. Schlegel and most
other writers give prioriiy to Bulweri of Jardine and Selby's Illustrations, a
work extending over a series of years. It is figured in volume ii. pi. 65 ; but
the title page bears no date. If not published anterior to 1829 then the name
anjinho Heineken has priority.

through the kindness of my friend Dr. P. L. Sclater, of London, of the identi-

in the Proceedings of the Zoological Society as Pterodroma Carribmi, Carte. I
was surprised at learning that it is a "Pterodroma" as I had confidently
anticipated that it would prove to be one of the Prionese ; po-sibly however
being prejudiced by the following note upon it by Richard Hill, Esq.-)- " From
the dimensions of our bird, 13 inches long, by some 26 inches in the extent of

physis slight, the tip a little decurved. The interrarnal space is narrow, and
densely feathered to the symphysis. The nasal tubes are exceedingly short,
but broad, high, and turgid, the median line only obsoletely carinated. Their
apex is very obliquely truncated, not at all emarginated. The orifice is large,
and nearly circular ; the internasal septum very thin, and not extending to the
termination of the nasal case. The frontal feathers extend far on the base of
the bill, running forward on the nasal case with a narrowly rounded termina-
tion, and sloping rapidly backwards and obliquely downwards. The outline
of the base of ihe nasal tubes is thus rendered nearly as oblique as their
apex.

The wings are rather short, when folded not reaching to the end of the tail.
The second primary is not much shorter than the first. All the primaries are
rather narrow, regularly tapering to their somewhat acute tips. The tertials
and inner primaries are much abbreviated, making the distance in the folded
wing, from their tips to the end of the first primary unusually great. The tail
is very long, broad, and but slightly rounded, ami is contained only about
twice in the wing from the carpal joint. All the rectrices are broad to their
very tips ; which latter are squarely truncated.

The tarsus is as long as the middle toe; moderately stout and compressed ;
covered with small somewhat elongated irregularly shaped plates, which are
rough and elevated, especially posteriorly, and are not notably different in size
or shape on the two aspects of the tarsus. Thetibire are feathered to very near
the joint. The inner lateral toe with its claw barely reaches the base of the
middle claw. The outer lateral toe is longer than the middle; its claw how-
ever so short, as hardly to rf ach to the tip of the middle claw. Claws are
rather large, little curved, moderately compressed and acute ; the inner edge
of the middle one dilated. The hallux is unusually developed, and somewhat
depressed in situation ; long, stout, acute, and a little curved.

The size is moderate; the form compact and robust; the color entirely pure
white.

This is one of the most remarkable generic types of the Proccllariinx. It is
doubtless most nearly related to Daptioh, with which genus its " build " cor-
responds closely. But, as will be seen on comparing the diagnosis given, it
differs in many details of structure, particularly those relating to the bill. From
^■Estrelata the pecularities of bill, of the hallux, comparative lengths of wings
and tail, etc., readily distinguish it. The genus has a " physiognomy" or
" facial aspect " that is peculiarly its own. The long depressed sloping fore-
head is found in no other Procellaridian. This is produced mainly by the flat-
tening and elongation of the bones composing the forehead ; but aided to a
considerable degree by the great forward extension of the frontal feathers,
which gives to the bill and nasal tubes their extreme brevity ; causes such a
long rictus ; and places the eye, apparently, at so great a distance from the
corneous base of the bill.

Independently of differences in absolute size of body, the species presents
unending variations in size, and, to some degree, in shape, of the bill. Speci-
mens differ in this respect by as much as a fourth of the whole length of the

bill, which may be quite unaccompanied by corresponding differences as to
depth or width. The length of the nasal tubes, and the amount of turgidity,
and obliquity of truncation vary greatly. Differences in the depth and robust-
ness of bill are surprisingly great.

I have never seen, of many specimens, any which were separable specifi-
cally from the typical form. But some individuals are so strikingly small,
that were it not for intermediate sizes, they might readily*be supposed distinct.
Upon this charncter a variety minor was founded by Bonaparte which has
been adopted by so accurate and cautious an ornithologist- as Dr. Schlegel.

The only synonym of note I have met with is candidus of Peale, (1848.) The
original description of P. nivea by Gmelin speaks of black shafts of some of the
feathers. As Mr. Cassin justly remarks (Orn. U. S. Ex. Exped. 1858, p. 416)
should this ever.be found to characterize a species, the present must bear Mr.
Peale's name of Candida. I think it probable that dark spots or streaks would
be indicative of inmaturity ; but being unfamiliar with the plumage of very
young birds, I cannot speak with certainty.

The bill is much shorter than the skull, about three-fourths the tarsus,
rather more than two-thirds the middle toe, very stout, depressed, about as
broad as high for its whole length as far as the unguis, where it is suddenly
much compressed and higher than broad. Culmen is about straight or a little
concave from the nostrils to the root of the unguis, which latter is moderately
large, but not very convex nor much decurved. The lateral outline of the bill
is decidedly convex from its base to the unguis where the convexity suddenly
ceases; it is produced by the large, inflated and protuberant lateral lamina?
Just inside the cutting edge of- the bill is a series of oblique rugae, extending
the whole length of the bill. The lateral sulcus is well defined, running from
the base of the nasal case to the unguis, obliquely downwards and forwards ;
it is most distinct posteriorly, more shallow anteriorly, where it merges into
the depressed portion of the culmen. The lower mandible is perpendicularly
narrow, but horizontally is unusually broad, the rami widely diverging from
each other immediately from the symphysis. The gonys is short, scarcely con-
vex in outline, its angle small and inconspicuous. The interramal space is
very broad, in consequence of the wide divergence of the inferior mandibular
rami, and their mutual concavity. The rictus is exceedingly ample; and the
capacity of the fauces increased still more by the looseness and dilatability of
the enclosed skin. The feathers on the side of the lower mandible extend but
a short distance ; those in the interramal space only as far as a point opposite
the end of the nasal tubes; and by no means fill the space from side to side
when the skin is at all distended.

The nasal case is very long for a component of the group JEstrelatesr, being
a third as long as the culmen. It is broad, depressed, a little more elevated
towards the apex, its dorsal outline a little concave and moderately carinated.
The orifice is subcircular, nearly vertically truncated, a little emarginated.

The wings are of moderate length, about equal to the tail when they are
folded. The second primary is nearly as long as the first; the rest rapidly
graduated. The tail is rather short, contained about two and a half, times in
the wing from the carpus ; is moderately and very evenly rounded ; the rec-
trices being broad to their extreme tips. The upper tail coverts fall an inch
short of the end of the tail ; the inferior ones quite reach its extremity.

But a very brief portion of the tibia is naked of feathers. The tarsus is much
shorter than the middle toe and claw, about equal to the inner toe ; very stout,
though much compressed ; covered externally with very small, irregularly sub-
circular plates ; which on the inner aspect are much larger and more regular

in shape; the median series of them so broad as to nearly stretch across the
inner face of the tarsus. The inner toe is short, the tip of its small weak claw
hardly reaching to the base of the middle claw. The outer toe without its
claw is decidedly longer than the middle one ; but the much greater size of the
claw of the latter makes up the difference. The hallux is large and stout; a
straight, almost perfectly conical, moderately acute, claw.

This genus is trenchantly separated from all others by the characters of the
bill ; in the lateral dilatation of which, the widely divaricating rami of the un-
der mandible, and the partially naked and distensible skin of the interramal
space, there is seen an approach to Prion of the Procellariince, and also to Pele-
canoides of the Halodrominse. The superior lateral mandibular laminae are so
wide and large, and so inflated, that they give a bulging convex lateral outline
to the bill. In the same manner the inferior mandibular rami rapidly diverge
from each other, their concavities presenting to the interramal space. In all
these points there is an interesting resemblarce to the genus Pelecanoides ; fur-
ther heightened by the broad ample rictus, loose dilatable skin of the floor of
the mouth, which is only partially feathered. These peculiarities are not shared
by any other genus of Procellariinse except Prion ; and leaving out of considera-
tion the widely diverse nostrils, the bills of Pelecanoides urinatrix and Daption
capensis are very similar in shape.

The genus is of moderate size, of robust and compact form, and variegated
in the distribution of its colors. Its only known species is the type upon which
it is based, the well known D. capensis.

This is one of the three species of Procellaria given by Linnaeus in 1758. It

has remarkably few synonyms, in consequence of its marked characteristics.

lis features are so well known that no mention of them is necessary in this

connection, as the peculiarities of its bill have been elucidated under the head

of the genus.

Section PRIONEJE.

The presence of laminated serrations along the inner edge of the upper man-
dible so trenchantly defines this group, that further characterization is unnec-
essary. A great similarity of color is found to prevail throughout.

After elimination of the genus Halobzena on the ground of its square tail
and some other peculiarities, I find among the so-called Prions two very dis-
similar types ; which I consider as of generic import, and am therefore com-
pelled, however reluctantly, to separate under a new designation.

The three genera here recognized may be thus distinguished : —

A. Bill compressed, its unguis large, its serrations moderate in extent, or con-

fined to the base of the upper mandible.

I. Tail truncated Halobsena.

II. Tail graduated Pseudoprion.

B. Bill excessively dilated, depressed, its unguis small and weak ; the serra-

tions large and perfect to the extremity of the bill.

III. Tail graduated Prion.

Chs. Bill provided with a few laminated serrations at the sides of the base
of the upper mandible, just within the commissural edge of the upper mandi-
ble ; in length slightly less than the tarsus, equal to the inner toe without its
claw; slender, compressed throughout, a little higher than wide at the base.
Superior lateral sulcus well marked, nearly straight ; inferior shallow and in-
distinct. Unguis of upper mandible small, short, only moderately convex. In-
ferior unguis acute, much decurved, the gonys very concave, the ramal outline
straight. Interramal space fully feathered. Nasal tubes only a fifth the length
of the culmen, short, narrow, elevated, compressed, not carinated, terminally
obliquely truncated; nares narrowly oval. Folded wings reach far beyond tail.
Tail contained rather more than 2\ times in the wings from the carpal joint ;
square, with no graduation of the lateral feathers: all the rectrices so broadly
rounded as to be nearly truncated. Tarsus equal to middle toe without claw ;
outer rather longer than the middle ; but its claw so short as to make its total
length rather less than that of the middle. Tip of inner claw just reaching
base of middle.

The principal character which distinguishes this genus lies in the short,
square tail; a feature which is quite unique in this family, being found in no
other genus of the Procellariida. Its type and only known species is the old
ccerulea of Gmelin, a small delicately formed species, whose colors tend chiefly
to bluish and white.

In general features of external form, proportions of tarsus and toes, and par-
ticularly the shape of the bill, which is much compressed, this genus is quite
similar to JEstrelata, especially to such of its smaller species as mollis and Cookii.
Nevertheless, the presence towards the base of the bill of distinct serrated
laminae, which constitute the essence of the Prionitic type,* indubitably fix its
position among the latter group, to which also it so closely approximates in
color. These laminaj only exist for a short distance on either side of the base of
the bill ; but still they are quite palpable and decided in character; perhaps as
much so as in Pseudoprion turtur or ariel. The small and rather weak unguis,
which does not begin to curve almost directly from the unguis, is essentially
Prionitic, as distinguished from typical JEstrelatines. The bill though higher
than broad in its whole length, is hardly more compressed than in P. turtur.
From these considerations, and esteeming, as I believe justly, that the lamina-
tions are the essential character of the Prionece. and consequently more weighty
than all others, I include the somewhat anomalous genus in this latter group.
I regard it as the connecting link between the JEstrelatem, on the one band,
through the genus Daption, and the Prionex on the other, towards the true
type of which latter it approximates through the subtypical genus Pseudo-
prion.

I quote the reference to Isidore Geoffroy on the authority of Bonaparte, not
having the means at hand of verifying the citation. I do not know what spe-
cies is typical in the original founding of the genus. If it be the one named
Halobsena typica in the Conspectus, then Halobsena is equivalent to, and has
priority over my Pseudoprion ; and a generic name is wanting for the /'. cceru-
lea of Gmelin.

* In some genera not of the Prionere, e. g. Daption, Ossifraga, etc., there are to be found along
the inner border of the cutting edge of the upper mandible, a series of ruga? or alternate depres-
sions and ridges, obliquely placed. These, however, are part of the mandible itself, and by no means
distinct elements, and therefore are radically different in morphological character from the lami-
na? of the Prionex.

Color. There is a short and not very conspicuous infra-ocular white line,
and a superciliary streak of the same color; but not, however, running far
down on the auriculars behind the eye. Above the bird is of a clear cinere-
ous or grayish blue ; extendirg as delicate clouding around the sides of the
breast ; and deepening on the head, most of the wing-coverts, the outer edgc3
and tips of the four outer primaries, into brownish ash. It is chiefly the lesser
wing coverts that are thus darkened; most of the greater ones being nearly as
clear as the back. The secondaries and tertials are clear cinereous, edged
and tipped with white; their inner webs being almost wholly of this color.
The iuner vanes of all the primaries, but particularly of the first four, are
almost wholly pearly white except at their tips. The upper tail coverts ere
concolor with the back. The exterior pair of rectrices are white, with dark
brown shafts; the next two are colored like the back; the rest similar ex-
cept that a fuscous hue deadens the cinereous towards the end of the feathers,
and their tips are squarely, trenchantly, and purely white ; each for an in-
creasing dit-tance from without inwards. Forehead, cheeks, lower auricular.-1,
under surface of wings and whole under parts of the body pure white.

Younger birds may be known by a less decidedly cinereous or bluish gray
tinge of the upper parts ; which tend more or less strongly towards brownish.
The forehead is not pure white but mixed with about an equal amount of
brownish ash. I have never seen specimens entirely fuscous or brownish
ci'<ereous below; but think it probable that such a state of plumage charac-
terizes very young birds.

(ur, ariel and ? brevirostris, and Prion proper, the following comparison is in-
stituted.

The fringe of laminae is smaller and weaker, and inflected inwards rather
than descending vertically ; and it is either restricted to a short space near the
base of the b\\Y (turlur, ariel, ? brevirostris) being quite obsolete more anterior-
ly; or if as in Banksii it extends to the unguis, it is small, weak and incon-
spicuous. The lateral lamellae of the bill have scarcely more of development
and inflation than in other genera of Procellariinse, instead of being immensely
hypertrophied ; and they have a lateral, vertical aspect, instead of a superior
nearly horizontal one. The commissural edge of the upper mandible looks
downwards, with little inflation or reflection outwards, and nearly (though not
quite except apically) touches the under mandible. There is no groove for
the reception of the fringe of the upper mandible; but in its place the ordinary
lateral sulcus of the sides of the lower mandible is apparent, though not very
strongly marked. The inferior mandibular rami divaricate at an acute angle,
and are quite straight, instead of widely diverging with a mutual concavity.
The submental space, narrow and triangular instead of broadly conoidal, is
quite fully feathered, instead of nearly naked ; and doubtless has little of the
distensibility which characterizes that of Prion. The extent of the feathers on
the lower mandible is much more restricted. The unguis of the bill is larger,
stronger, more convex, its tip more decurved, the chord of its convexity form-
ing more instead of less than a third of the length of the culmen. The lateral
outline of the bill is straight not convex. The tail is shorter than in Prion,
being contained nearly twice in the wing ; and it is less cuneiform, The nos-
trils and the proportions of the feet, are as in Prion ; while the entire simi-
larity, almost identity, of the coloration has doubtless had much to do with
the referring of the species of this genus to Prioo.

In the following antithetical table the main diagnostic points of the two
genera are contrasted.

This species may be readily recognized by the continuation io the unguis of
the fringe of laminas, whereas in the others of the genus it is confined to a
short sp .ce near the base of the bill. The laminations are, however, very
small anteriorly ; and are somewhat deflected inwards.

In colors the species of both Pseudoprion and I'rion are so nearly identical
that, compared with Prion vittatus, the present species seems to differ in hardly
aught else than in the less amount of blackish towards the tail. On the mid-
dle feathers it is about an inch in depth ; laterally decreasing so rapidly that
there is hardly a trace of it on the three outermost. The bill and feet, how-
ever, are differently colored.

A species absolutely identical with P. Banksii in colors of plumage ; but
readily to be distinguished from that species by its somewhat smaller size, de-
cidedly slenderer and more compressed bill, and especially by the restriction
of the fringe of laminas to the base of the bill, and their very incomplete de-
velopment. The bill and feet are described as similarly colored with those of
Prion vittatus ; the webs flesh colored. The following measurements, particu-
larly of the bill, taken from a specimen in the Philadelphia Academy, are to be
compared with those of Banksii above given.

Chord of culmen 1-00 ; width of bill at base 0-33 ; height at base 0-37; at
unguis the same. Nasal tubes 0-18 ; tarsus 1-15; middle toe and claw 1-45;

^Authors agree in identifying' the Pr. turtur of Banks' and Solander's ineditae
with the species beautifully figured by Mr. Gould under this name, and dis-
tinguished from Banksii by the characters given in the preceding pHragraphs.

1 have not been able to find where thig species is originally described by
Mr. Gould, if it has been at all more than named by him. From Dr. Sehlegel's
description* of typical specimens received by him from Mr. Gould, it appears
to have exactly the colors, and the development of the lamina: of the bill which
obtain in P. turtnr ; and to be distinguished from that species by its smaller
size; and a very slender bill, wider than high at the base.

Synonymy. It is a little uncertain to which species the P. turlur of Kuhl' 3
Monograph, No. 14, fig. 8, really refers. The figure of the bill agrees quite
nearly with a specimen of the turtur Gould, of the preceding article of this
paper; but the description given by Dr. Kuhl, and especially the measure-
ments rather seem to indicate the present species, ariel, Gould. But Dr. Kuhl
also gives the measurements " Avis aliquantum major," which rather are those
of the true turtur. There are cited Bank's turtur, pi. 15, and also Pr. velox
Banks, pi. 16, as synonyma ; the first of which (according to most authors)
representing the turtur of Mr. Gould, and of this paper ; the second indicating
the true ariel of Gould. Under the circumstances, it is evident that Kubl's
turlur may be, without violence, referred to either of the two species; and
authors are about equally divided in opinion regarding it.

Bonaparte's Conspectus does not admit ariel as a valid species ; but has
instead a certain Halobiena typica, Bp. based upon a specimen in the Paris
Museum. He cites "turtur" Lesson, Kuhl, fig. 8, and "velox?" Banks, pi. 16,
as synonyms; and his diagnosis presents no points forbidding the reference of
this H. typica to the Prion ariel of Gould, with which Dr. Schlegel considers
it as synonymous.

I am only acquainted with this supposed species by the plate and descrip-

description does not indicate any tangible points of difference from P. ariel.
By Gray, and, I believe, also by the majority of writers, it is considered as a
synonym of P. ariel.

The essential characters of this genus lie in the peculiar shape of the bill
and the coriiplete development of the serrated laminae, which are the dis-
tinguishing features of the group of which it is typical. The modifications to
which the bill is subjected produce a result which, compared with other Pro-
cellaridie, may be likened to that seen in the genus Cuncroma among the

Ardeidcc. I have not met with as detailed a description of its peculiarities
as seems desirable.

The culmen, from the extremity of the nasal case to the root of the unguis,
is quite straight. Though rising up as a conspicuous ridge between the deep
longitudinal sulci on either side, its outline is broad, flat, depressed, and not
carinated. The unguis of tbe upper mandible is small and weak, and hardly
rises above the level of the culmen proper; its convexity and decurvation are
slight.

On either side of the culmen, from the root of the nasal case to the junction
of the lateral mandibular lamellae with the unguis, lies a well-marked, deep
longitudinal sulcus ; the central line of which depression, from the end of the
nostrils to the unguis, is occupied by a distinctly defined ridge.

The immensely-developed lateral lamellae of the superior mandible have so
great a lateral extension, as to make the width of the bill at its broadest part
nearly two-thirds its length. These lamellae are arched and inflated through-
out : and their surface is superior, not lateral. The free commissural edge is
convex in outline; retreating slightly inwards and backwards from the
broadest point of the bill, which is a little in advance of its extreme base ;
converging more rapidly and nearly in a straight line thence to the unguis ; it
is dilated and bulging posteriorly where it overhangs, but by no means meets
or touches, the inferior mandibular rami ; more anteriorly, it is deflected
downwards, and terminally rests against the unguis of the lower mandible.

From the under surface of the lateral lamella near its free edge grow a
series of serrated laminae, which extend from the very angle of the mouth to
the unguis ; their ou'line corresponding nearly to that of the edge of the
lamella whence they spring. They are directed downwards, with a little out-
ward and forward inclination. They are longest, largest, and their " set " is
most oblique at the broadest point of the bill ; whence, as they proceed either
forwards or backwards, they diminish in size and become more vertical in
direction. It is this fringe of serrations that is in apposition with the under
jaw ; forming, therefore, the true commissural edge of the upper mandible.
These laminae are, so to speak, a series of plates, antero-posteriorly thin,
elastic and yielding; transversely wide and resisting; whence it results that
ihey can readily be bent away from each other ; but the series cannot be
laterally deflected, as a whole; exactly as is the case with the teeth of a
comb.

The nasal tubes are very short, measuring hardly more than a fifth the
length of the culmen and unguis ; broad and depressed; placed conspicuously
hieh upon the base of the culmen. They are somewhat more elevated api-
cally than basally ; their apex is so deeply emarginate as to cause a partial
segregation of the two tubes towards their termination. The orifice of each
naris is circular; the internasal septum rather wide.

Corresponding with the general shape of the upper, the lower mandible is
very broad ; its rami widely divaricating, presenting much concavity towards
each other. Its cutting edge is very sharp and strongly sinuate for its whole
length, being curved in several planes oblique to each other. From the
widest point, which is opposite the extremity of the feathers on its side, the
rami rapidly converge to the unguis ; which latter is very small and weak, its
gonys very concave in outline, its tip acute and much decurved. There is
hardly an eminentia symphysis.

The true lateral sulcus of the rami, seen in most Procellariinse, is wanting.
In its place we have, ju3t external to the true cutting edge of the lower man-
dible, a groove which extends the whole length of the ramus; deepest and
most marked posteriorly; apically becoming obsolete. This groove, owing
to the inflection of the edge of the mandibular ramus, looks upwards and
outwards, and into it the fringe of laminae are received. More anteriorly
where the groove is obsolete, the teeth simply abut against the side of the
under mandible.

NATURAL SCIENCES OF PHILADELPHIA. 169

The broad space between the widely-separated, mutually concave inferior
mandibular rami is occupied by soft, more or less distensible skin, naked of
feathers, except a small triangular wedge which extends forwards from the
base only to a point but a little in advance of the termination of the feathers
on the side of the lower mandible. Even this patch does not fill the space
from side to side. The feathers on the side of the lower mandible extend as
far as the broadest point of the bill. The frontal feathers project a little on
the nasal ^ase. Retreating somewhat, they then stretch transversely across
the base of the lateral lamella1, with no obliquity backwards, to the very edge
of the bill ; which is thence densely feathered to the angula oris.

Bill about as long as the tarsus ; the latter equal to middle toe without its
claw; covered with quite regular hexagonal plates, largest antero-interiorly.
Outer toe and claw about equal to middle. Tip of inner reaching base of
middle. Hallux strong, straight, conical, placed rather low down. Folded
wings not surpassing tail. First and second primaries about equal ; last suc-
cessively more rapidly graduated. Tail long; two-thirds the wing from the
carpus, or contained one and a half times in it; cuneate ; central rectrices
acuminately rounded and somewhat projecting; lateral ones more broadly-
rounded and much graduated in length.

Critical Review of the Family PROCELLARIIDiE ;— Part V ; embracing the
DIOMEDEIN.E and the HALODEOMINiE. With a General Supplement.

BY ELLIOTT COUES, M. D., U. S. A.

The group composed of the Albatrosses is so trenchantly distinguished from
all other Natatojes, that for its definite characterization it is only necessary to
advert to the absence of the hallux, and to the position of the rhinothecas. In
other morphological points the Albatrosses conform closely to the type of
structure which obtains throughout the Procellariinx.

The Halodromes, if really components of the family Procellariidce, are the
most curiously aberrant of all the Gavix or Longipennine Natatores. They
appear to hold a quite anomalous position, intermediate between several nata-
torial suborders. The very short falcate wings, no less than the absence of the
hallux ; the general configuration of the body, and especially the position of
the posterior extremities relative to the axis of the body; as well as the com-
pactly imbricated, glossy plumage ; indicate a close aflinity with the Urinatores,
or Brachypterous Natatores. These structural resemblances are borne out by
the attitudes, habits, and mode of life of the species, so far as we are acquain-
ted with them ; which are rather those of Guillemots than of Petrels. The
dilation of the bill, particularly of the under mandible, and the partially naked
and distensible submental skin, which forms an imperfect pouch, point to a
type of structure extensively prevailing among the Totipalmi. Most of the lat-
ter have the rhynchotheca segmented ; so that almost the only character of the
Halodromes which is strictly Procellaridian is the tubulation of the rhinothe-
ca ; and even in this feature the details of shape and direction of axis are en-
tirely unique. So far indeed as external characters are concerned, arguments
are adducible for their reference to either of the three tribes above alluded to ;
and especially to the Urinatores. It remains for the scalpel to finally deter-
mine their true affinities.

By Illiger* the tubulation of the rhinotheca has been made indicative of a
tribe {although called a family) Tubinares, which is attaching to it a value
coordinate with such a character as e. g. the membranous union of the hallux

* Prodromus, 1811, p. 274.

NATURAL SCIENCES OP PHILADELPHIA. 173

with the inner anterior digit, which defines what we now recognize as the tribe
or rather suborder Totipalmi, embracing numerous families. Proceeding upon
this basis we should be obliged in like manner to form a tribe or suborder
" Linear inares " of what is now known as the family Laridx, and erect its four
recognized subfamilies into as many families.

By Bonaparte* the order Gaviae is made to consist of two tribes, the Toti-
palmi and the Longipennx ; the latter containing two families, — Laridx and
Proccllariidse — the differences between which essentially rest in the linear or
tubular form of the nostrils; for continuity or division of the corneous rostral
envelope does not always point to one or the other family, as the Lestridinw of
the Laridce have somewhat the features of the ProcellariidcB in this respect. In
this arrangement an essentially brachypterous bird, — one truly a "diver"
rather than a "flyer " in the sense in which these words are technically ap-
posed— is classed among the Longipennines.

If a tubular rbinotheca be really the most essential feature, and at the same
time of no more than family value, then its modifications may with propriety be
held as indicative of three subfamilies Diomedeinse, Frocellariinen, and Ilalodro-
minsa. But it is questionable whether such be indeed the case. An approach
to this feature is seen in the Les(ridi?ite, (of a family otherwise exhibiting
strictly linear basal nostrils, aud an undivided rhynehotheca ;) in which the
so-called "cere" is really a segmentation of the corneous envelope and pro-
bably also indicative of tubulation of the nares. It is by no means proven
that the peculiar nostrils of the 1'rocellariidx as generally defined, should not
be held as subsidiary in importance to, or at least of no more than coordinate
value with, other points of structure. Upon such an hypothesis the birds now
called Procellariidx would be divisible into ihree families, somewhat accord-
ing to ihe following schedule : —

I. Tridactyle.

A. Maciopterous ; "flyers;" the tubular nostrils disjoined,

lateral, horizontal Diomedeidm.

B. Brachypterous; "divers;" the tubular nostrils united.

culminal, vertical Halodromidce.

II. Tetradactyle.

Macropterous; " flyers ; " the tubular nostrils united, cul-
minal, horizontal Proccllariidse.

But this arrangement is as faulty as the others, in the presence of an incon-
gruous brachypterous element; and we should moreover be obliged to recog-
Lize a tribe or suborder for the three families thus collocated.

It will be evident, therefore, that so long as we regard a tubular rbinotheca
as a primary fundamental character, not permitting of a wide separation of the
forms in which it is present, we shall bring into juxtaposition certain types
widely dissimilar from each other in most other respects ; and that we do not
obviate this difficulty when we make this character indicative of a suborder,
under which several families may be ranged, any more than in considering it
as of family importance, aDd forming our subfamilies upon its modifications.
In either case we are met by the same objection. It remains to be proven that
tubulation of the external nares is not a feature of subordinate importance to
others and as such, one whifh may coexist in types otherwise presenting a
widely diverse assemblage of characters. In which event, at least one genus
now held as Procellaridian will be found to constitute a family of quite a dif-
ferent suborder ; and certain others will form at least a family distinct from
that of the Petrels proper. The test of anatomical investigation must be ap-
plied before the question can be definitely settled ; for in one sense external
characters of every sort are but the indices, as it were, of fundamental struc-

tural modifications ; and as such unavailable for the truly scientific definition
of groups of a higher grade than families.

In calling attention to the foregoing considerations, I wish to be understood
as offering no opinion upon the questions involved, and particularly as by no
means asserting that the Halodromes are not true Procellaridians. It is rarely
of use to exchange one doubtful opinion for another ; and for the present I
shall follow the usually received classification. But it is safe to affirm that by
the determination of the proper affinities of these birds the exact value of the
character of tubulation of the rhinotheca is to be ascertained.

Subfamily DIOMBDEINJE.

In a careful study of the Albatrosses, the interesting fact becomes evident,
that we have an easy and convenient means of accurate diagnosis of species in
the characters afforded us by the bill alone. All the known species differ from
each other by perfectly tangible and readily appreciable variations in the size,
shape and color of the bill ; in the configuration of its several corneous ele-
ments, and in the outline of the feathers around its base. This latter feature,
conjointly with the shape of the corneous covering of the culmen in that por-
tion of its extent which is posterior to the nares, gives us such reliable data
that we need hardly enquire further. I shall, theiefore, in the following pages
confine myself chiefly to detailed descriptions of the bill ; and it will be noticed,
as supporting the foregoing assertions, that a synoptical table may be drawn
up solely upon the characters mentioned above.

As we shall study the bill somewhat in detail, I introduce, for convenience
of description, several words expressive of the different corneous elements
which cover it; the meaning of which will be obvious. I may remark that the
piece interposed between the inferior mandibular rami at the lower border of
their symphysis (here called the " interramicorn,") is a feature which also
definitely characterizes this group, as it is present in no other. The presence
of a well defined membranous fringe on the exterior toes is also highly charac-
teristic.

In the following pages I describe eleven species — one of them supposed to be
new — and indicate the possible existence of a twelfth. Of these one differs so
much from the rest that it may be properly made the type of a genus distinct
from Diomedea. The remaining species have also been subdivided into several
genera, chiefly by Prof. Reichenbach. Such a collocation of species is cer-
tainly natural, regarded as simply expressive of the fact that certain of them
are more intimately allied to each other, than they are to the species of another
group ; but the differences presented seem hardly sufficient to warrant our at-
taching generic import to them. The following will serve to explain the point
alluded to.

Group A. Comprising exidans, brachyura, nigripes, gibbosa. Of largest and
medium size. The bill is very broad, stout and heavy ; and especially very
wide at its base, and is uniform in color. The colors of the plumage are white,
variegated with black, especially upon the wings; or uniform fuliginous. The
tail is very short. The nostrils are large, and wide. Exulans may be consid-
ered as typical of this group. The length of tail reaches its minimum in bra-
chyura, upon which character Prof. Reichenbach founds his genus Phcebas-
tria.

Group B. Comprising melanophrys, Gilliana, n. sp. cauta, culminata, chloro-
rhyneha, olivaceirostris. Of medium and rather small size. Bill shorter, weaker,
and considerably compressed, usnally bright or parti-colored. White, with black
back and wings. Tail long, slightly rounded. Melanophrys may be taken as the
type of this group, which constitutes the genus 21halassarche Reich. Both mela-
nophrys and Gilliana differ from the other three species in the character of the
culminicorn, as will be hereafter more particularly elucidated.

So varying are the characters of shape of bill, outline of frontal feathers,
length of tail, etc., that I think they can hardly be made typical of distinct

Habitat. — Southern Hemisphere at large ; ranging to a considerable distance
north in the Pacific.

The great size of this species renders it easy of recognition in any of its very
diverse plumages. I will confine myself to a description of the bill, the gen-
eral features of which may be taken as the standard of reference for all the
species of the subfamily.

The frontal feathers form a rather obtuse angle on the forehead, whence they
run forward on the side of the upper mandible to a point a little posterior to the
root of the nostrils ; whence, with a slight backward obliquity, they extend to
the commissure. On the side of the lower mandible tbey come forward far
beyond those on the upper, and have a very convex — almost angular — outline.
This latter feature is constant, and of great value in distinguishing small exu-
lans from large brachyura when both are in fuliginous plumage. (Compare
outline as described under brachyura.) The point, of greatest extension is
nearly opposite the middle of the nosirils. The frontal feathers form a more
reentrant concavity on the forehead, and a more salient convexity on the side
of the lower mandible, than in any other species except fuliginosa.

By gentle maceration in warm water, into which a little potassa or soda has
been thrown, the various corneous elements of the bill readily separate from
it and from each other, so that we can advantageously study them.

The " culminicorn" is transversely broad a >d rounded, but may be some-
what compressed or even a little cannated ; a great difference in these
respects being observable in a large series of bills. Its dorsal outline descends
in a nearly straight line from the base to the middle of the bill; whence it
more rapidly rises with much concavity to the base of the UDguis. Its inferior
border is curved with a convex border from its distal extremity to the
nostrils ; then a considerable concavity is formed by the cutting away of a
space for the emergence of the nostrils. Behind these, it again dips down with
a salient convexity to join the upper edge of the latericorn ; their union, how-
ever, being rather a point than a line. The outline of the base corresponds
with that of the frontal feathers above given; and there are usually found a
few corrugations parallel with this outline. The distal extremity is more or
less fused with the superior unguicorn or dertrotheca, especially on the median
line of the culmen.

The " latericorn " corresponds in its superficies with the shape of the mandi-

bular ramus of the intermaxillary. Its superior border is nearly straight for its
whole length ; no emargination existing opposite the nostrils, nor hardly any
decurvation in its terminal portion. A corneous ridge, incompletely fused with
it, separates its true superior border from the inferior border of the culraini-
corn — occupying the length of the sulcus from the nostrils to its termination.
Its inferior border is sharp and regularly curved in outline for its whole length.
Internal to the commissural edge, it extends as an exceedingly delicate, thin
lamina to line the roof of the mouth, fusing, anterior to the palatal fissure,
with its fellow of the other side; more posteriorly distinct, and descending to
cover the large swollen palatal bones, which latter make a prominent ridge on
either side of the roof of the mouth towards its posterior part. The basal
outline of the latericorn is that of the lateral frontal feathers, as above
described. It terminates in an acute angle anteriorly.

The " unguicorn " or dertrotheca is large and strong, in size, shape and
general appearance calling irresistibly to mind the claw of one of the large
Felidx. It is much thicker, heavier and stouter than any other of the corneous
elements. The convexity of its dorsal outline is great, being more than the
quadrant of a circle. Its commissural edges are thin and sharp, very concave
in outline: usually with an obsolete tooth, or, at least, a slight lobe.

The " naricorn " or rhinotheca is an irregularly convoluted little scroll, very
thin, and delicate in texture. Its general shape is that of a turgid cone,
whose apex presents backwards, and whose obliquely-truncated, irregularly-
shaped base is anterior. This is simply inserted in the emargination of the
under edge of the culminicorn, above described. A corneous parietes is want-
ing on the side which lies towards the median line of the bill; and, more
auteriorly, there are numerous delicate convolutions, impossible to describe
intelligibly. The general effect of these, however, is to produce a division into
two parts of each nasal orifice, by a process which projects upwards and
inwards. When the naricorns are in situ, the outer of these divisions, irre-
gularly circular in shape, forms the most conspicuous part, and looks forward
and a little upwards. The inner is much smaller, aud hidden under a project-
ing ridge ; and its aspect is quite lateral.

The "ramicorn" which covers the sides of the rami of the lower mandible is
chiefly noticeable for the peculiar outline of its base, which, as already stated,
formed the distinguishing feature of the under mandible of this species. It is
deeply concave in outline ; the superior cornu of the semilune running as an
acute process, far upwards and backwards to the commissural termination.
Terminally, the fusion with the inferior unguicorn is very incomplete. Its supe-
rior border runs downwards with a long concave sweep from base to tip ;
having posteriorly an obsolete groove for the reception of a ridge from the
upper mandible. Inside the mouth, more anteriorly, the inner face of the
ramicorn presents an elongated extensive ridge, whose superior aspect is con-
cave, both longitudinally and transversely. This ridge rises higher and
higher as it proceeds forward, till at its termination it is on a level with the
commissural edge. The ridge in the bone itself is slight in size, compared
with that produced by the folding over it of the heavy corneous covering.

The "inferior unguicorn" or myxotheca is subrectangular in its lateral
aspect, the antero-superior angle being rounded off, and its posterior margin a
little convex. Its tomial edges are sharp ; and rise considerably above the
edges of the bone they cover.

The " int^rramicorn" forms the gonal element of the bill. It is narrow, elon-
gated and subcylindrical in shape; anteriorly completely fused with the myx-
otheca; posteriorly extending on the median line a considerable distance into
the interramal space, running to a fine point, and very gradually merging its
corneous texture into that of ordinary dermal tissue.

The general shape of the bill appears sufficiently elucidated in the preced-
ing descriptions of its several elements. The features whereby it is differ-
entiated from that of any other species are these : Its great size, (chord of

eulmen 6-50 to 7-50;) its great breadth and strength ; width and concavity of
the eulmen; huge, strong unguis; peculiar convolutions of the naricorn ;*
the outline of the feathers, particularly on the side of the under mandible ; and
the uniform, very light yellowish color. These points will always separate
from brachyura specimens of every variety of size and color.

The D. spadicea of Gmelin and Latham is now universally conceded to be
based upon the young of this species. Latham's spadicea var. B., however, I
consider to be the young brachyura, for reasons stated elsewhere.

Moils. R. P. Lesson, holding that spadicea is distinct from exulans, commi's
the curious error of citing in support of his views a note sent him by Dr.
Garnot, which refers to Phocbetria futiginosa.f

Diomedea adusta Tsch. seems hardly different from this species, to which it is
unhesitatingly referred by Dr. Schlegel.

As is the case with other species, this one is readily diagnosticable by its
bill alone. This is of the same fundamental characier as that of exulans ; but
it is smaller, weaker, more compressed, with a vastly less concave eulmen, less
elevated, robust, and more attenuated and decurved unguis; and there is a
very marked difference in the outline of the feathers around its base.

Tbe frontal feathers embrace the bill in a near'y straight Hue as far as the
lateral sulcus; forming almost no concavity on the eulmen. Along the base
of the latericorn, they run slightly obliquely backwards to the commissure.
On the sides of the lower mandible they extend but slightly further than ou
the upper, having a scarcely convex outline.

The bill is stout, being especially wide at its base, which is large and heavy.
Anterior to the nostrils, the culminicorn is compressed, and sometimes obso-
letely carinated ; posterior to them, it very rapidly flattens and widens, and
extends so far downwards on either side that there is allowed no projection of
the post ro- superior corner of the latericorn. Ttte latter, with the exception
of this feature, and of a straighter commissural edge, is much as in exulans.

The dertrum is comparatively small : hardly rises above the level of tbe
r/ulmen; and is by no means so convex and hooked at the tip as in exulans.
The myxa is longer, narrower and more attenuated.

The straigbtness of the commissure as compared with that of exulans; and
the different ou line of the feathers on the side of the lower mandible, are the
main points whercia the outline of the ramicorus of the two species differ.
The nostrils are as in exulans, but smaller. The variations in plumage of

this species are quite parallel with those of exulans, and need not detain us, as
they are well known. A shining rusty yellow suffusion of the feathers of the
head and neck is met with in perhaps the majority of adult specimens.

That this species is the spadicea var. B. of Latham, as above, when in the
fuliginous state of plumage, is evidenced, if not by Latham's brief description,
by his citation of PI. Enl., No. 963, which gives correctly the outline of the
frontal feathers and other points, whereby it is distinguishable from the young
exulans. The same plate is also cited by Temminck himself as representing
the young brachyura.

A specimen before me, unquestionably brachyura, is in precisely the state of
plumage described under the name epomophora by Lesson in his works above
cited, and recognized as a valid species by Tschudi and Bonaparte. The
relative amount of black and white on the wings is very variable, tbe latter
color sometimes pervading all the coverts; and at others being restricted to a
small spot at the elbow, producing the appearance which suggested Lesson's
name.

The questions arising from the confounding of nigripes Audubon with this
spfcies are discussed under head of the latter.

Note. — I find in the Smithsonian Institution a skull of an Albatross, want-
ing tbe lower jaw, in general features mott like that of brachyura, (numerous
examples of which are before me,) but differing as follows : —

It is considerably narrower and smaller in nearly all of its dimensions ; the
bill especially being slenderer, weaker and more compressed, with a less ele-
vated and smaller unguis. The frontal outline is decidedly more concave on
the median line. The culminicorn was narrower and less flattened basally :
did not descend so low to meet the latericorn behind the nostrils, and was
more convex along its dorsal outline. The fronto-maxillary suture is nar-
rower. The palatal bones are smaller and narrower, and sink to the level of
the commissural edge murh sooner.

A most marked difference is seen in the supra-orbital fossa for the lodgment
of the gland, whose secretion is poured into the nasal cavity. It is very
soi*U, and particularly narrow ; so that, the least width between it and its
fellow is greater than in brachyura, although the skull is narrower. These
fossae have no floors whatever on their anterior halves.

Numerous other minor differences may be summed up as resulting from the
smallness and narrowness of the skull, which is well illustrated by the follow-
ing measurements. It will be noted that the bill is absolutely longer, and
therefore still more comparatively elongated than in brachyura.

Description* Bill about a third longer than the head, slightly surpassing the
tarsus, equal to the middle toe without its claw : comparatively stouter, and
basally wider, than that of any other species (except gibbosa?). The culmen
is perfectly straight to the middle of the bill; and has thence only a just
appreciable concavity to the unguis ; which latter is weak and small, scarcely
rises above the level of the culmen proper, and is only moderately decurved
and acute. The culminicorn is moderately wide, and subcnrinated beyond the
nostrils ; posterior to them it is flatter and wider, spreading down so far on
either side as to overlap the upper edge of the latericorn. Its comparative
width is greater than in any other species. Although the basal outline i3
essentially rounded, as in brachyura, there is yet a slight angle formed on the
median line, readily perceptible, which is not the case in brachyura. The
great comparative width of the bill is produced chiefly by the turgid and pro-
tuberant latericorns, which give it an air of great thickness and solidity. Tne
lateral sulcus is nearly straight from nostrils to unguis, and thence is only
slightly decurved. The commissure is almost straight to the unguis. The
outline of the inferior mandibular rami is quite straight to the inferior unguis.
the point of which is somewhat elongated and decurved. The interramicorn
is small and short, though quite convex in outline. The feathers on the side of
the lower mandible extend further than on the upper ; their outline has a gentle
convexity. The nostrils are of moderate size ; very short ; rather obliquely
placed, presenting upwards and forwards ; and the emargination of the cul-
minicorn, to allow of their protrusion, is very deep.

The tail is of moderate length, contained about three times in the wing from
the carpal joint ; is nearly square, the feathers having but a slight graduation,
and all being broad to their very tips. (The tail of brachyura is contained
about 31 times in the wing.)

The tarsus is less than the middle toe without its claw, about equal to the
inner without its claw ; slender, moderatelv compressed. The outer toe is
longer than the middle ; the tips of the claws fall together. The tip of the
inner claw about reaches the base of the middle one.

The plumage is dark chocolate brown ; lighter and rather tending to plum-
beous gray on the under parts generally. Some of the dorsal feathers, and
most of the wing-coverts, have light grayish brown edges, as if faded ; and a
few feathers on the elbow are whitish except terminally. The region all around
the bill is hoary white for a limited space ; and then shades rapidly into the
prevailing color of the head. A streak over arid behind the eye and a spot
just in front of it are nearly pure black. The primary quills are black, with a
plumbeous cast on their inner vanes; their shafts bright yellow to near the
tips. The tail is brownish black; paler below; the shafts dull whitish except
apically. The long upper tail coverts which reach within one and a half
inches of the end of the tail, are lighter brown than the rest of the upper parts,
having sometimes a slight rufous tint. The feet and webs are black. The
bill in the dry state is dark brown, almost black on the nail; its basal por-
tions with a hoary glaucescence, its median portions tinged with reddish
brown.

Chord of culmen 4-00, its curve 4-60, from feathers on side of upper mandi-
ble to its tip 3-50; ditto lower mandible 3-20; height of bill at base 1-50;
greatest width 1-25. Tarsus 3-70 ; middle toe and claw 4-50, outer do. 4-50,

batross, very abundant in the North Pacific. It is readily distinguishable from
the young brachyura, to which it assimilates so closely in its plumage, by its
bill, which Dr. Schlegel has happily described as " tres court, quoique gros."
The shortness of the bill ; its great width, especially basally where the cul-
minicorn is so broad and descends so low as to ovetlap the latericorn ; the
general straightness of its several outlines, and its color ; the relative propor-
tions of the wings and tail ; and the proportions and color of the feet, all fur-
nish data ample for its separation from brachyura. So far as now known, tbe
fuliginous plumage above described is its only one ; but should it ever assume
a livery like that of brachyura, still the above points of form will readily char-
acterize it. The only question then is as to the came to be employed for it.
American writeis have without exception identified the " nigripes " of Audu
bon with the young brachyura.

Unfortunately I cannot find the type specimen of nigripes among the many
types of other species of Mr. Audubon now in the Smithsonian Museum. I have
before me the types of his " chlororhynchos " and " fusca ; " but " nigripes "
has been mislaid. We have therefore only his description as a guide ; from
which we must determine whether he had in view the present sp< cies or a
young brachyura, also found on the Pacific, coast of North America. In the
latter event nigripes would become a synonym, and a new name be required for
the species now under consideration.

Examining the dimensions given by Audubon we find several discrepancies.
In general they may be stated as too large. The bill is by no means '' five"
inches long, — especially along the edge of the under mandible. The tail is six
or more instead of " three " inches. The dimension given for the inner toe
(ljfl) is doubtless a typographical error. By carefully measuring Audubon's
specimen of "chlororhynchos," I find that he took the curve of the culmen,
not its chord. Applying this test to the specimens before me tbey measure
4-50 to 4-75 inches ; which is sufficiently near the dimensions he states. But
five inches along the edge of the under msndible is too great, even for the
majority of adult brachyura; while three inches as the length of tail, is wide of
the mark for either species. Eliminating palpable errors however, there is
nothing in his description or measurements absolutely incompatible with the
present species, though much confirming a suspicion that he may really have
had a young brachyura in view ; and I therefore think it best, at least until his
tj pe can be found, to accept his name, now well established, for this species,
■ especially as the necessity for a new one will thereby be obviated.

Of this species, which is autcptically unknown to me, Mr. Gould says: "It

and raised form of the upper mandible, whiflfa moreover rises high up on the

This supposed species is by Mr. G. R. Gray placed as a synonym of nigripes
Audubon. The dimensions and description in general accord well ; ana cer-

impossible that gibbosa is based upon the fully adult nigripes, in a plumage
unknown until described by Mr. Gould. But comparisons of specimens are

and of authors generally.

Habitat. — Southern Oceaus generally.

The bill is moderately compressed throughout, least so at the base where
it is very high or deep. The culmen is transversely rounded, non-carinated ;
its dorsal outliue moderately concave, descending from the forehead nearly
in a straight line to near the middle of the bill, whence it gradually ascends
to the unguis. The latter is very convex and much decurved, though not
rising so high as in some other species. The culminicorn basally descends a
little on either side to overlap the roots of the nostrils, and to coalesce witli
the latericorn ; no space of soft skin being interposed. The lateral sulcus fol-
lows very nearly the curve of the culmen, to near the unguis, where it rapidly
decurves. The commissural edge of the upper mandible is lightly curved.
The outline of the rami of the inferior mandible is nearly straight; the inter-
ramicorn somewhat protuberant, and extending far into the submental space.
The inferior unguicorn is much compressed, not very deep, its apex rather
acute, but little attenuated.

The nostrils are short and small; quite different in this feature from those
of exulans or brachyura. They are subconical in general shape ; being consid-
erably dilated anteriorly, and basally narrowirg to a point ; their orifices con-
siderably dilated, with thin margins ; suboval in shape, looking upwards and
forwards. This description of nostril is applicable to the other species of this
subdivision of the genus.

The frontal feathers embrace the base of the bill in a nearly straight line ;
hiving a slight forward obliquity, however, as they descend on the sides of
the upper mandible. On the culmen a very slightly reentrant curve (not angle)
is formed. On the side of the lower mandible the feathers begin slightly pos-
terior to their termination on the upper; extending somewhat forward, and
with a slight convexity, as they go downwards.

The bill is yellow, more or less pure and uniform in tint ; in immature birds
clouded with brown. Some portion of the unguis is usually dark colored.
The soft skin at the extreme base of the bill makes a narrow black line all
around.

White; back plumbeous black, more cinereous anteriorly, where it merges
gradually into the white of the neck. Wings and tail black; the latter with
a grayish or plumbeous tinge, especially basally. Shafts of quills yellowish,

Belonging to the group of white, black-backed Albatrosses of which melano-
phrys is typical, and with the characters of the culminicorn generally as in that
species. The shape of the bill, however, most nearly approaches that of cul-
minata ; but the characters of the culminicorn posterior to the nostrils are
quite diverse from those of the latter species, as follows : —

Instead of continuing, between the nostrils and the forehead, no broader
than it is anterior to them, it there widens, descending on either side to over-
lap their roots, and to coalesce by a simple sulcus with the upper edge of the
latericorn. There is thus left no space to be filled by soft skin. Tee dorsal

outline of the culminicorn is not so concave as in culminate/; does not begin
to curve downwards so immediately from the forehead ; does not dip so low
down at the middle of the bill ; is less flattened and depressed on top, and has
a more decidedly rounded transverse outline. The culminicorn has considera-
bly more of lateral extension downwards before it reaches the lateral sulcus.
The outline of the frontal feathers shows an approach to the character seen
in fuliginosa ; the root of the culmen extending nearly as far up on the fore-
head as in exulans. Still the outline is a simple concavity, not a sharp reent-
rant angle. On the sides of the lower mandible the feathers start a little pos-
terior to their termination on the upper and curve downwards and considera-
bly forwards with a decidedly convex outline.

The base of the culminicorn and latericorn are transversely rugose ; the cor-
rugations being mainly parallel with the outline of the frontal feathers.

The lateral sulcus is gently curved from base to unguis ; and on its ungual
extent is less deflected than in any other species. The interramicorn is promi-
nent; and extremely elongated before it finally looses itself in the submental
space.

In the dried specimen the bill presents none of the bright parti-coloration of
culminata, chlororhyncha, and cauta ; while its color as well as its shape are
sufficiently diverse from those of melanophrys. It is a plain uniform olivaceous
brownish throughout; the ungues darker, and inclining to black ; the extreme
tip of the upper mandible yellowish. That this color is not an evidence of
immaturity is evinced by the plumage which is palpably that of a fully adult
bird.

Cnord of the culmen 5 00 inches. Height of bill at base 1-75 ; a't middle
slightly over one inch ; at unguis 1-12. Width at base 1-45. Tarsus 3-00;
middle toe 4-V5, outer toe 4-60, inner toe 4-00. Wing about 20 00 ; tail about
900.

The coloration of the plumage is that of melanophrys and the rest of this
group, with this exception : The whole under surface of the wings is concolor
with the upper ; whereas in the other species a large area is white.

In carefully examining the superb series of Albatrosses in the Philadelphia
Academy, which contains examples of all known species except olivaceirostris
and gibbosa, I find a specimen of which the preceding paragraphs are descrip-
tive. It is unlabelled as to name, locality or donor; and Mr. Cassin has no
recollection whence it was obtained. I find it impossible to refer it to any
known species ; and am therefore constrained, somewhat reluctantly, to regard
it as a previously undescribed one. I am autopically familiar with all the re-
cognized species except olivaceirostris and gibbosa. The former of these is said
to have a bill " 3 inches and tbree-eignths long from the gape to the tip, and of
a uniform olive green, and in form more slender and elegant," etc. ; with which
description the characters of our bird are totally discordant. There is no
" peculiar swollen and raised form of the upper mandible " suggestive of the
name gibbosa, or rendering its reference to that species admissable.

From chlororhyncha, culminata, and cauta it is at once distinguished by the
color of the bill and especially by the lateral extension downwards of the base
of the culminicorn, and its coalescence with the latericorn, thus cutting off the
naked space which exists behind the nostrils of these species.

Agreeing in this latter respect with melanophrys, the shape no less than the
coloration of the hill, as well as the peculiar color of the under surfaces of the
wings forbid its reference to that species. Until these features are shown to
be accidental, or not incompatible with the variations to which melanophrys is
subject, the species must be regarded as a valid one ; since there are no others
than those above compared, to which it bears any sort of resemblance.

I trust that this species may prove valid, if for no other reason than that it
may continue to bear the name I have fixed to it in pleasant remembrance of
years of uninterrupted friendly intercourse ; although Professor Theodore Gill
needs no such slight tribute from me, to enhance the enviable reputation to

Habitat. — From the south coast of Van Diemen's Land.

A beautiful species having the colors of plumage of the melanophrys group ;
readily distinguishable from all other species by the following peculiarities in
the shape and color of the bill, and outline of the frontal feathers.

The frontal feathers lie in a straight or slightly convex outline across the
base of the culmen, and then descend perprtidicularly to the commissure ;
forming a slight reeentrant angle on each side of the base of the culminicorn.
From exactly opposite their termination on the commissural edge of the upper
mandible those on the lower start, and descend in a straight line with a
slight forward obliquity, forming a very obtuse angle with those on the upper
mandible.

The dorsal outline of the culmen descends from the forehead with a gentle
curve, to rise again on the unguis, but not so high as at the forehead. The
point of greatest concavity is opposite the middle of the bill. Basally the
culminicorn agrees with that of culminata and chlororhyncha, and differs from
melanophrys, in not widening behind the notnls, nor descending to overlap
their bases and meet the upper edge of the latericorn ; a uarro.v sub-
rectangular space thus left being covered only with soft skin.

The latericorn is very broad throughout as compared with the culminicorn ;
i. e., the lateral sulcus is placed high up. The latericorn is exceedingly deep
at its base, running high up towards the sides of the ba>e of the culminicorn,
and, in consequence of the strong upward inflection of the commissure
towards its base, the sides of the under mandible are also very deep basally,
and run high up to form an acute angle with the feathers at the commissure.

The nostrils present no discrepancies from other species of this group.

"Bill light vinous gray or bluish horn color, except on the culmen where
it is more yellow, particularly at the base ; the upper mandible is surrounded
at the base by a narrow belt of black, which also extends on each side of the
culmen to the nostrils; base of lower mandible surrounded by a belt of rich
orange, which extends to the corners of the mouth." (Gould.)

Chord of culmen 475 ; height at b-tse 1-90; width 1-25; height at unguis
1*25; from feathers ou lower mandible to the tip of its unguis 3-75. Tarsus
3-25 ; middle toe 5-00 ; outer toe 4-75 ; inner 4-25 ; wing 22-00 ; tail 10-00.

The plumage is th it of melanophri/s even to the transocular dark fascia ; but
this in the specimen before me extends quite to the bill, which is not the case
in the numerous specimens of melanoplirys examined.

A suffusion of the head and neck with pearly gray is doubtless indicative
of immaturity, as is the case with other species.

This bird is superbly figured in Mr. Gould's and Mr. Gray's plates cited
above. The latter is an exceedingly accurate delineation of the bill.

This species in color of plumage is quite identical with chlororhyncha, and
the bill, in its general characteristics of shape, most resembles that of the
latter species. But the bird is much larger, stouter and heavier, as will he
seen by comparing the dimensions given. The bill in general terms may be
stated to be heavier and stronger, though not longer than that chlororhyncha ;

much less compressed ; deeper at the middle, notwithstanding that the con-
cavity of the cuhnen is much greater; and with other wall-marked peculiar-
ities, as follows : —

The dorsal outline is exceedingly concave, dipping down rapidly from the
forehead, and then again being much elevated on the ungual portion. The
culminicoru is broad, flattened, depressed, with no trace of carination. Its
colored base, instead of being acutely pointed, (as in chlororhyncha,) con-
tinues of a uniform width past the nostrils to the feathers, where it is broadly
rounded with a geitle convexity. Tnere exists posterior to the nostrils a
naked space of soft skin ; but this is trapezoidal, not triangular in shape, in
coosequ<-nee of the different shape of the base of the culminicorn, just
described.

The lateral sulcus is nearly straight to the unguis, where it is greatly
deflected. It runs high up along the bill; or ra'her the dorsal outline of the
cultnen dips, towards the middle of the bill, so far down, that it almost lies
on a level with this sulcus. The culminicoru is thus allowed scarcely any-
thing of a lateral aspect in the middle portion of its extent. The latericorn,
as a consequence, is very deep throughout, and its commissural outline is
de-idedly less curved. The two ungues are stout, deep and short; with con-
siderable more convexity of outline, and less elongation and decurvation of
their apices than is seen in chlororhyncha.

The dorsal outline of the inferior mandibular rami is quite straight. The
interraniicoru is prominent, but not so long as in chlororhyncha.

The outline of the feathers is almost exactly as in melanophrys ; i. e., they
lie over the base of the culmen iu nearly a straight line, or with a slight con-
cavity ; and thence extend nearly straight down the sides of the bill. There
is no trace of the reentrant angles at the sides of the base of the culminicoru
seen in chlororhyncha. The feathers on the lower mandible have the same out-
line as those of melanophrys or chlororhyncha.

The colors of the bill are quite different from those of any other species,
though coming nearest to chlororhyncha. The culminicorn is clear light yel-
low ; (not bright orange ;) and the edges of the inferior mandibular rami for
three fourths their extent are also yellow. There is no yellow line along the
sides of the base of the lower mandible at its junction with the feathers. The
rest of the bill is black. " In its youthful state the head and neck arj dark
^ray, and the bill is of an almost uniform brownish black, with only an indica-
tion of the lighter color of the culmen." (Gould.)

The plumage is quite the same as that of chlororhyncha. The color of the
back is darkest posteriorly, being anteriorly more plumbeous, and shading
into the grayish pearl which washes the neck and head of the majority of
specimens. Usually the feathers about the eyes are more or less dark-colored.

In young birds the whole head and neck is clouded with plumbeous gray ;
and the transocular fascia is more conspicuous.

Bill (chord of culmen) 4-50; height at base 1-75 ; at middle 1-10, at unguis

I have before me Audubon's type of the u chlororhynchos" of his works. It
is an example of culminata Gould ; and was doubtless procured elsewhere
than "not far from the Columbia River," as falsely stated. This specimen
(No. 2726 of the Smithsonian Register) is also described by Mr. Lawrence,
1. c, under the same name.

I have a distinct impre-sion of hiving seen, in some old work, a plate of
this species (as evidenced by the yellow along the ramus of the under man-
dible inste-id of at its feathered base) under the name of " chlororhynchos ;"
but I cannot now call to mind the reference.

tralian and South Pacific Oceaus generally.

T:ie bill is compresned in it? who'e extent more than in any other species
except fuliginosa ; and although somewhat stouter at the ba;e, it is there very
high as compared with its widih. Its dorsal outline is very concave, descend-
ing rapidly from a point a little anterior to the extreme base of the bill, to
about the middle; and not rising; again very high on the unguis. Although
the culminicorn is narrow and with compressed sides, it is not carinated along
ltr> dorsal lin*. It has a peculiar termination basally, quite uuique iti the genus,
which single character separates it trenchantly from any other Albatross. The
culminicora does not (as in exulams, melanopkrys, etc.,) spread downwards and
outwards behind the nostrils to overlap their bases, but terminates by rapidly
narrowing to an acute angle on the median line of the bill. Its hard, brightly
colored, pointed base does no' quite reach to the feathers. There is thus left,
between the base of the culmi'cicorn and the upper edge of ihe latericorn, a
somewhat triangular space of sottish integument, not brightly colored ; and
corrugated in the dry state.

The lateral sulcus on the upper mandible does not extend further towards
the base of the bill than the nostrils : the soft skin just spoken of taking its
place thence to the feathers. Beginning then with the nostrils, it has a slight
downward convexity as far as the unguis; thence it, is greatly deflected. As
Qsual, a slight ridge lies in this sulcus for its whole length. The commissural
edge of the upper mandible is strongly curved, its convexity looking down-
wards. The dorsal outline of the inferior mandibular rami is straight or very
slightly concave. The inter rami corn is thin, not very prominent, but pro-
longed far nl >ng the chin before it merges into soft skin.

The two ungues, taken t gether, are characterized by their slight compara-
tive depth and degree of convexity, and their extreme compression and
elongation ; and by the acuteness and rlecurvation of their apices.

The nostrils are exactly as described under melanopkrys.

The frontal fea:hers arp peculiar in outline. They lie straight across the
bise of the culmen, or even have a slight convexity, as far as the upper corner
of ihe base of the latericorn. Thence ibey descend the side of the bill, with a
slightly convex outline, and some little obliquity forwards ; forming more de-
cidedly reentrant angles at the superior basal cornets of the latericorns than is
found in any other species. On the side of the lower mandible, beginning at a
point slightly posterior to their termination on the upper mandible, they de-
scend with an outline parallel to that of those on the upper mandible.

specimens is clouded with pearly gray. There is more or less of a grayish
plumbeous transocular fascia, as in melanopkrys. The culminicorn is bright
orange yellow ; and a narrow line of the same color lies along the sides of the
bfise of the und- r mandible. The rest of the bill is blackish ; there being no
bright color along the dorsal outline of the inferior mandibular rami, as seen
in culminata. The feet are livid flesh, or bluUh white.

Habitat. Southern oceans at large.

The bill of this species is remarkable in its extreme compression; its basal
outline ; and the presence of a sulcus on the lower mandible.

The feathers retreat rapidly, with a gentle curve, from their point of great-
est development on the commissural edge of the upper mandible to form an ex-
ceedingly acute reentrant angle on the forehead. Those on the side of the lower
mandible extend in an exceedingly acute salient angle, to a point much beyond
the termination of the nostrils ; their upper outline a trifle oblique to the com-
missural edge of the lower mandible ; their under more decidedly oblique to
the outline of the inferior mandibular rami.

The culminicoru is much compressed, with but slightly convex sides, and
a decidedly carinated ridge. The dorsal outline forms a gentle and continu-
ous curve from the very feathers to the base of the unguis. The latter hardly
rises above the level of the culmen proper: is rather the reverse of robust ;
its top moderately decurved, and only slightly'overhanging the lower. The
curve of the superior lateral sulcus is intermediate between exulans and
brachyura. The commissure forms a gentle and continuous curve from the
base of the unguis.

The commissural edge of the under mandible corresponds to that of the
upper. The dorsal outline of the rami is perfectly straight. The inferior
unguicorn is convex and protuberant, but extends only a short distance into
the mental space.

The median longitudinal lateral sulcus of the lower mandible terminates
abruptly at the unguis. Basally it divaricates to receive the salient feathers ;
the upper cms being the best marked, and forming the real continuation of
the sulcus. This groove is sometimes concolor with the bill ; more often it
is brightly colored, being yellow or pinkish.

The nostrils are peculiar in their very small calibre, perhaps less than that
of any other species. They are almost buried between the culminal and late-
ral elements of the bill, the two meeting posterior to the nares. The orifice
is subcircular, presenting forwards and upwards with no lateral aspect.

The graduation of the lateral rectrices is enhanced in producing a cuneate
tail, by the elongation of the median pair which project beyond the next
ones, and are narrowly accuminate. The tips of the lateral feathers are
rounded.

NATURAL SCIENCES OF PHILADELPHIA. 187

The bill is black, except its sulcus. The feet are flesh colored or dull
whitish, becoming yellowish in the dried state. The edges of the eyelids are
pure white except just at the anterior canthus.

The perfectly and uniformly fuliginous color (darkest about the face and on
the wings and lail) which is the ordinary plumage, sometimes gives way to a
much lighter, clearer and more cinereous color. Examples of this coloration,
doubtless due to age, are in the Philadelphia Academy and Smithsonian In-
stitution. The most extreme case I have met with is as follows : Neck all
around, upper part of back and whole under parts nebulated with ashy or
grayish white. Lower part of back, wing-coverts, scapulars, etc., light
plumbeous gray. Wings and tail ashy or plumbeous blackish, lightest on their
inner webs, their shafts chiefly whitish. On the face, crown and sides of
the head the fuliginous holds, deepest in tint immediately around the bill.
The nape and hind neck, and some of the wing coverts show traces of ferru-
giueous.

Chord of culmen 4 to 4-50, height of bill at base 1-50, at unguis 1-00, width
at base -75. From feathers on commissure to tip 3-50, from feathers on lower
mandible 2.50. Tarsus about 3-00 ; middle toe and claw 4-75, outer 4-50, inner

Concerning these numerous names which have been proposed for this genus

[May,

NATURAL SCIENCES OF PHILADELPHIA. 189

the preponderance of authority is in favor of the adoption of that of Illiger.
I can, however, discern no cause why Lacepede's name should be superseded.
The reasons given by Illiger, in proposing Haladroma, and by Lesson in
founding Puffinuria, certainly seem invalid. To G. R. Gray is. I believe, due
the credit of restoring the rightful appellation of Lac6pede.

The type which represents the genus, although so curiously anomalous, is
so well known, that a detailed description would be out of place here. Only
a few of its more salient points need be noticed.

The perfectly vertical nostrils are surrounded by an elevated wall, whose
contour, in consequence of a slight emargination posteriorly, and a corres-
ponding protuberance anteriorly, on the median line, is somewhat cordiform.
The wall has considerable thickness basally ; but much bevelling superiorly
gives it an extremely thin edge. The internasal septum is moderately thick ;
and from either side a process projects transversely into the nasal orifice. In
shape each nostril is suboval ; being somewhat elongated anteriorly, and a
straightening of its inner border being produced by their mutual appo-
sition.

The dertrum or unguis is long, reaching quite to the nostrils ; and, for this
family, is only moderately uncinated. Except at its extreme base it is dis-
tinctly carinated, aud its sides are much compressed.

The myxa is unusually small and narrow, with a very acute tip, and ex-
tremely concave gonys. The sulci separating the myxotheca from the rest of
the mandible, and the lateral one on the gnathidia are strongly marked.

The unusual amount of divarication of the concavo-convex gnathidia, which
causes so wide a submentum, is, in the upper mandible, accompanied by a
corresponding dilation of the lateral elements ; which latter are also turgid
and inflated.

The tarsus is excessively compressed, and at the same time very deep
antero-posteriorly ; giving to its transverse section a narrowly elliptical shape,
like that which obtains in the Colymbidas. It is reticulated as in the Procel-
laridse, and also the majority of the Alcidcc, though Mtrgulus has anteriorly
transverse imbricated scales. The proportions of the anterior toes are as in
the other Procellariidce.

In the wings and tail the urinatorial aspect is most decidedly marked.
The very short wings, with their stiff, falcate, subacuminate primaries hardly
reach to the end of the exceedingly abbreviated tail.

The plumage is essentially diverse from that of any other Prgcellaridian, in
its compact imbrication, and oily glossiness, which comes nearest to that of
the Loons; and is eminently adapted to resist the action of the water in
which the habits of this species cause them so constantly to be submerged.

Concerning the number of species *o be enumerated authors are greatly at
variance. To a comparatively recent date but a single oue was supposed to ex-
ist. M. Temmiuck, in figuring the type of MM. Quoy and Gaimard's P.
Berardii, is of opinion that both urinatrix and Garnoti should be referred to it.
M. Lesson, after describing Puffinuria Garnoti in 182G, doubtfully refers it to
Proc. urinatrix Gm.* Prince Bonaparte unites Garnoti and urinatrix, and con-
siders Berardii&s distinct. Mr. G. R. Gray, and more recently, Dr. H. Scble-
gel agree in regarding all three of the supposed species as valid. A sufficient
amount of material is not at my disposal to settle these doubtful points. In
a considerable number of specimens from various localities I can see what
has been called P. Berardi, differing in some respects from the ordinary type :
but have failed to detect tangible differences indicating three species. Very
possibly, however, none of the specimens before me indicate the true urinatrix,
as distinguished from Garnoti.

The three supposed species are based entirely upon size: a varying degree
of length or robustness of bill : and coloration of the feet. Some specimens

190 PROCEEDINGS OF THE ACADEMY OP

before me are larger than is indicated by Dr. Schlegel as characteristic of
Garnoti : while the feet are colored as in the smallest species, Berardii. A
considerable amount of variation is found in examples of undoubtedly the
same species ; so that perhaps we might without great violence consider the
different species as extremes of a single very variable type.

I am mainly indebted to Dr. Schlegel's excellent article for characters
whereby to tabulate the supposed species with their synonyms. This author
has had before him examples which he has considered as indicative of three
species : and for the present I rely upon his judgment.

It will be observed that the differences between the size of the smallest and
largest of these supposed species is not great ; that an intermediate form oc-
curs between the two extremes ; that each is liable to considerable variations
in size; and that the colors of the plumage of all three are identical.

Recapitulation.
The following is a summary of the genera and species of Procellariidce
treated of in the series of papers of which the present article is conclusive.
The numbers in the third column are those of species which I have recog-
nized, but which seem to require confirmation before their claims to validity
can be considered as fully established. It will be seen that more or less of
doubt attaches to 17 out of the 92 described.

Note. The following supposed species are not given in the body of my
papers ; and I only know of them by the descriptions.

Puffinus Rollandii Quoy and Gairaard, in Freynete, Voy. Antour du Monde ;
and Zool. Journ. iii. p. 271.

Procellaria lugubris, Tschudi, Cab. Journ. f. Ornith. 1856, iv. p. 185, (not of
Natterer.) " The whole body is dark brown ; the back somewhat deeper col-
ored than the belly; the tail wholly black ; the inner side of the wing darker
than the outer. Bill and feet reddish ; iris ashy gray. Surpasses in size ea-
pensis ; also compressed in form. The description of P. antarctica is too in-
accurate to say with certainty if it be the species here described. Between
46° and 36°." [Tschudi, ut supra.) It is impossible to say from the descrip-
tion what species of Nectris or Pterodroma this is.

Procellaria maculata, loc. cit. "Island of Juan Fernandez; 33° S. Head,
breast and belly wholly white; the back bluish-white with darker spots, the
wings gray with bluish spots, the tips of the four longest primaries wholly
black. Tail fan-shaped, grayish blue. Bill and feet deep orange yellow. Iris
dark brown. About the size of the preceding species." Evidently an JEstre-
lata ; but the description applies to no species with which I am acquainted.
It comes nearest to alba Lath, or Lessonii Garnot.

Procellaria bicolor, op. cit. p. 187. "Bill and feet black; neck, back, and
lesser wing coverts deep blackish gray, wing feathers and tail somewhat
lighter. Head and throat wholly black; belly pure white." Doubtless a
young .Eslrelata ; but of what species the description gives no hint.

SUPPLEMENT.

Some few additions to, and corrections of my previous papers, which sub-
sequent investigation has brought to my knowledge, may with propriety be
inserted here.

Procellariese.

P. 79, line 25, for "size" read "length." H. microsoma is rather smaller
than P. pelayica in actual size of body, though the length of wings and tail is
not less. This explains an apparent descrepancy in my statements on p. 79
and p. 90.

* I would now unite Thiellus and Nectris with Puffinus, leaving but three gonera to be recog-
nized.

t These six are Buhveria MacgilUvragi and Proeellaria ParJcinsoni, Gray ; P. neglecla and P.
incerta Schl.; ySCstreiata grisea and M. gavia of my paper.

X Prion brevirostris Gould.

j Which are P. trthys Bp., P. lugubris Natterer, P. melitensis Schembri; Thalassidroma Segethi
Ph. and Ldbk. ; Fiegctta Luivrencii Bp.

JS P. seric.fus Less.

«[ D gibbosa Gould, which may be nigripcs Aud., and my D. leptnrhyncha.

** As just stated, the three recognized species of Pelecanoides require additional evidence to
prove conclusively that they are not merely the extremes of a single variable species.

1866.]

192 PROCEEDINGS OF THE ACADEMY OP

Pp. 80, 81, 90. There can be no doubt of the propriety of referring P. lugu-
bris Natterer, and P. melitensis Schembri, to pelagica L. Proc. tethys Bp., also
seems hardly distinct.

Pp. 81, 90. Thalassidroma fasciolata Tschudi has been recognized by other
writers as valid.

Pp. 84, 91. Oceanil.es segethi ex Ph. et Ldbk. is undoubtedly a synonym of
0. gracilis ex Elliot, as intimated in my paper.

Pp. 87, 91. Fregetta Lawrcncii Bp. is probably a synonym of grallaria Bp.
ex Vieill. as Mr. Lawrence himself originally believed. The point cannot now,
however, be positively determined, as the specimen is lost.

Pp. 88. 91. Bonaparte's identification of Linnaeus' Proc. frrgata, which I fol-
lowed, is by no means proven; and in view of the uncertainty attaching to
Linnaeus' diagnosis (which may refer to some species of the genus Fregetta) it
may be as well to take our specific name from Latham's unequivocal indica-
tion of P. marina ; calling the species Pelagodroma marina after Reichenbach.

Fujfinese.

Pp. 122, 142, 143. Genera " Thiellus " and " Neetris." The points in which
these groups differ from Puffinus proper, are exceedingly trivial, as I state in
my paper. I am now indisposed to retain them, even on the plea of utility,
and would accordingly unite all their species under Puffinus.

Pp. 119, 141. Adamasfor Bp. According to Mr. G. R. Gray the type
of the genus Priofinus of Hombron and Jacquinot is based upon the bird Bo-
naparte calls Adam, lypus, and it has priority over Bonaparte's designation.
If this be the case the three species should stand as Priof. cinereus, Priof.
gelidus and Priof. sericeus.

Pp. 118, 141. Majaqucus Reich. If Proc. Parkinsoni Gray, (Ibis 1864) is a valid
species, it may belong to this genus rather than to the fuliginous group of
yEstrelata under which I have considered it. Additional data concerning it are
greatly to be desired.

P. 121. Add Daplion geHdurn Steph. Shaw's Gen. Zool. xiii. p. 245, to syno-
nyms of Adamastor gelidus.

P. 123. Puffinus fuliginosus. I have received specimens from the Pacific
coast of North America which I cannot distinguish from the common Atlantic
bird. It is quite different from the species I have named Puffinus amavriso-
ma, p. 124. By a misapprehension of a remark of Dr. Kuhl, I erroneously
state that fuliginosa Forst., Descr. sp. 18, is a species of Neciris ; whereas 1 am
now satisfied it is the same as Kuhl's sp. 12, which is ihe Pterodroma atlantica
of Bonaparte. Compare my remarks under JEstrelata fuliginosa in part iv. of
these papers. Kuhl's fuliginosa sp. 27, after Banks' tab. 23, is identified by Mr.
Gray with paeifica Lath.

P. 126. N. carneipes. On the authority of Dr. Schlegel I placed cinereusjuv.
Smith, and gama Bp. as synonyms of this species. Mr. Gray considers them
as referring to a species of Ncctr is or rather Puffinus not recognized in my pa-
per, viz.: P. tristis Forst. I am entirely unacquainted with this bird, if it be
a valid species. Bonaparte and Schlegel make it the same as tenuiroslrit
Temm.

Pp. 131, 144. A second specimen of Puffinus ere a lopus has been received
from the same locality.

Pp. 141, 144. Procellaria nugax Sol. This unpublished specific name should
not take precedence over assimilis of Gould.

Fulmarese.

Add Fulmarus antarcticus Steph. Shaw's Gen. Zool. 1825, xiii. p. 236, to the
Eynomyms of Thalassoica glacialoides.

' Add Daplion antarcticum op. cit. p. 242, to synonyms of Thalassoica antarc-
tica.

NATURAL SCIENCES OF PHILADELPHIA. 193

Bibliographical Appendix.

It may be well to give in this connection a synopsis of the works of some
of the older authors, as far as they relate to the subject in hand. The earlier
authorities to be particularly consulted in a study of the Procellariidse* are
the following : —

Linn-eus, Syst. Nat. ed. 10 (1758.)

In this edition, the first in which species are presented, there are named (p.
131) three species ; sc. pelagica, (type of genus Procellaria ;) wquinoctialis and
capensis.

Linnjeus, Syst. Nat. ed. 12, vol. i. (1766.)

1. Proc. pelagica, p. 212.

2. Proc. fregata,-p. 212. I followed Bonaparte's authority in referring this
name to the species subsequently named marina by Latham ; but there seems
to be nothing in the Linnajan diagnosis requiring this identification ; the name
being very probably based upon some species of the genus Fregetta as now re-
stricted.

3. Proc. glacialis, p. 213, = Fulmar us glacialis Leach.

4. Proc. lequinoctialis, p. 213, = Majaqueus lequinoctialis Reich.

5. Proc. capensis, p. 213, = Daption capensis Steph.

6. Proc. puffinus, p. 213,= probably P. anglorum (Ray.) Temm. Bas been
identified also with P. Kuhlii Boie, and P. major Fab., and almost every other
Atlantic Puffinus.

Gmelin, id. Linn. Syst. Nat. vol. i. part. ii. (1788.)

7. Proc. obscura, p. 559. Oue of the smaller Puffini, the habitat of which is
given as " insula nativitatis Christi." Now universally applied to the common,
bird of the Atlantic, called obscura by Vieillot, Nouv. Diet. p. 423, in 1817.

8. Proc. pacifica, p. 560. Not identified with any other known species. A
large Puffinus, from the island of Euopoa.

9. Proc. cozrulea, p. 560, = Halobsena carulea Bp.

10. Proc. vittatus, p. 560, = Prion vittata Lac£p.

11. Proc. urinatrix, p. 560, = Pelecanoides urinatriz Lace*p.

1. Proc. pelagica, p. 561. Variety B. is probably fictitious.

2. Proc. fregata, p. 561. Same as that of Linnams.

12. Proc. furcata, p. 561, = Oceanodroma furcata Reich.

13. Proc. fuliginosa, p. 562. Based upon Latham's species of this name,,
and not yet identified. A small species, eleven inches long, with a forked
tail ; from Otaheite. Generally supposed to be a species of Thalassidroma.

14. Proc. desolata, p. 562. Now recognized as a valid species of JEstrelata.

15. Proc. nivea, p. 562, = Pagodroma nivea Bp.

1 6. Proc. melanopus, p. 562. Not identifiable, except opinionatively. Evidently
some species of ^Estrelata. Said to come from North America, which would
make it referrible to JE. hxsitata. Description applies in most respects to
mollis Gould.

3. Proc. glacialis, p. 562, = Fulmarus glacialis Leach. The var. B. is the
Thalassoica glacialoides (Smith) Reich.

*The indications of the Diomedeinx are generally so definite that the consideration of them
may be here omitted.

18G6.J 13

194 PROCEEDINGS OF THE ACADEMY OF

17. Proc. cinerea, p. 563. A stumbling block, concerning which authors are
greatly at variance. Usually employed by European authors as the name of
the species I describe as Puffinus Kuhlii Boie ; and applied by American writers
to P. major Fab. By Bonaparte identified with his Adamastor typus ( = hsesi-
tata Forst. Gould, Reich, nee Kuhl, Temm. = Adamastor cinereus of my paper,)
in which opinion I entirely concur. According to Mr. Gray, the genus Prio-
finus Homb. et Jacq. is based upon this same bird, and antedates Adamastor of
Bonaparte. The proper name of the species in question would then be Prio-
finus cinereus.

18. Proc. gigantea, p. 563, = Ossifraga gigantea Reich.

19. Proc. brasiliana p. 564. Very dubious. May be the same as the pre-
ceding species ; or the Oracalus brasilianus, as identified by Bonaparte.

4. Proc. sequinoctialis, p. 564, and var. B., = Majaqueus sequinoctialis Reich.

20. Proc. grisea, p. 564. Unidentifiable.

21. Proc. gelida, p. 564. I think that this name was based upon the species
subsequently named flavirostris by Mr. Gould, the proper name of which ap-
pears to be Priofinus gelidus.

22. Proc. alba, p. 565. Evidently a species of JEstrelata, and probably some
one of the plumages of JE. Lessoni.

Latham, Index Ornithologicus, ii. (1790.)

Of Dr. Latham's three principal works this is the one usually referred to,
as being the only one in which Latin binomial names are used. Most of the
species given in this work have exactly the same import as those of Gmelin,
and need not therefore be noticed. The following are the chief points re-
quiring attention : —

6. Proc. alba, var. B., p. 822. — "Norfolk Island Petrel." A species subse-
quently named Proc. Phillippi by Gray, with which P. mollis Gould is consid-
ered as probably synonymous.

18. Proc. marina, p. 826. — First definite characterization of the type of the
genus Pelagodroma {Pel. fregata Bp. Pel. marina, Reich.)

21. Proc. Forsteri, p. 827, = Proc. vittata Gm.

23. Proc. pacifica p. 827. Same as that of Gmelin. The name is unidenti-
fiable, unless we regard it as expressive of a valid species. By Mr. Gray it is
so considered (Cat. Birds Pac. Isl.) and the'following cited as synonymous :
Nectris fuliginosus (Sol.) Banks, ic. 23. — Proc.fuliginosa Kuhl, sp. 27 ; (hxxmot
Kuhl's sp. 12 !) Puff, pacificus Gray, Gen. Birds, p. 647. It is a large Puffinus,
22 inches long, with flesh-colored bill and feet; from Euopoa.

24. Proc. obscura, p. 828, = that of Gmelin. By Mr. Gray this name is con-
sidered the same as that of Vieillot, (Nouv. Diet. xxv. p. 423, and Gal. Ois.
tab. 301 ;) and is made to include the Australian form (figured by Mr. Gould,
pi. 59 of the B. Aust. and named by him assimilis,) which is considered dis-
tinct by the majority of writers.

Vieillot, Nouv. Diet. oVHist. Nat. xxv. (1817.)

The article " Petrel " of this work is in general a close copy of Gmelin and
Latham. Certain points, however, may be noticed.
Proc. pelagica, p. 416. Mentions under this head the "Petrel 6chasse" of

Temminck.
Proc. grallaria, Vieill. p. 418. First name of the species subsequently named
leucogaster by Gould ; unless as is possibly the case fregata of Linnaeus
be this species rather than the Pelagodroma marina.
Proc.fuliginosa, p. 418. Latham's Otaheite species, whatever that maybe.

[May,

NATURAL SCIENCES OP PHILADELPHIA. 195

Proc. grisea, p. 419. Unidentified. = that of Gm. and Lath.

Proc. alba, j>. 419. Mentions under this head the "Norfolk Island Petrel,"
subsequently named P. Phillippii by G. R. Gray.

Proc. puffinus, p. 421, = Puff, anglorum. Cites PI. Enl. 962. The " Proc. puf-
finus var. Lath. PL Enl. No. 39 " may refer to Puffinus Kuhlii Boie.

Proc. pacifica, p. 422. " Se trouve en Europe " by error for " Euopoa."

Proc. sequinozialis, p. 422. Refers as a variety of this species to the " Kurile
Petrel " of Latham and Pennant, from Kamtschatca ; a bird now general-
ly supposed to be some species of Nectris ; which latter identification re-
quires confirmation.

Proc. leucorhoa, Vieill. p. 422. First designation of the Thalassidroma Leachii
Temm.

Proc. obscura, p. 423. Is this the same as Gmelin's species? This reference
to Vieillot should rather be cited for the name of the common small At-
lantic Puffinus.

Heinrich Kuhl, Beit. Zool. u. Vergl. Anat. (1820.)

In this work there is presented a " Beitriige zur Kenntniss der Procellari-
den " which is a very important contribution to the bibliography of the
family, marking perhaps the first decided advance over the writers of the
eighteenth century. The following species are given in this monograph :

1. Proc. /areata " L." p. 136. = Oceanodroma furcata Reich.

2. Proc. oceanica " Banks," p. 136. == Thalassidroma Wilsoni (P. pelagica
Wils.) of most ornithologists, now Oceanites oceanica mihi.

3. Proc. marina " Lath." p. 137. = Pelagodroma fregata Bp. and of my
paper ; Pelag. marina Reich.

4. Proc. Leachii "Temm." p. 137. = P. leucorrhoa Vieill. = Cymochorea
leucorrhoa Coues.

5. Proc. /regatta " Banks," p. 138. = P. grallaria Vieill. nee Licht, (= leu-
cogaster Gould.)

6. Proc. pelagina, p. 139. = P. pelagica Linn.

7. Proc. glacialis, p. 139. = Fulmarus glacialis Leach.

8. Proc. capensis, p. 140. = Daption capensis Steph.

9. Proc. gigantea, p. 140. = Ossifraga gigantea Reich.

10. Proc.cequinoctialis, p. 141. = Maj'aqueus cequinoclialis Reich.

11. Proc. hasitata " Porst." p. 142. But not of Forster. Kuhl's hasitata is
the same as that of Temminck, PL Col. 416, which is an JEstrelata. 'jEst.

12. Proc. fuliginosa, p. 142. = fuliginosa Forst. nee auct.. = Proc. atlantica

13. Proc. desolata, p. 143. = JEstrelata desolata Bp.

14. Proc. turlur, " Banks," p. 143. — I prefer Mr. Gould's identification of
this species to that of Dr. Schlegel. See remarks in my paper on Prionem.

says that he " thinks it is P. grisea L." which, according to his use of this
name, would make it the species described in my paper upon Dt. Schlegel's
authority as JEstrelata grisea.

21. Proc. " Forst. tab. 20," p. 145. An undetermined species.

22. Proc. puffinus, p. 146. == Puffinus major Fab.

28. Proc. vitiata p. 149. = Prion vittatus Lacep.

Stephens, Continuation of Shaw's General Zoology, xiii. (1825.)

This work closely adheres to Gmelin's and Latham's authority. A few
points may profitably be examined.

Proc. oceanica, p. 223. Not the Oceanites oceanica {Thalassidroma Wilsoni) but
a species of Pregetta, probably F. grallaria. Author refers to Forster ; to PI.
Enl. 993 ; to Temm. Man. p. 520 ; and to Bp. Journ. Acad. Phila. v. iii. p. 8.
On the followiug page (p. 224) " Proc. Wilsoni" is presented.

Puff, cinereus, p. 227. The synonyms adduced are chiefly those of Adamastor
cinereus ; description applies either to this latter or to Puffinus Kuhlii Boie ;
the description of the young would do for Puffinus major Fab.

Puff, sequinoctialis, p. 229. Cites Proc. pacifica Lath, as a queried synonym.

Puff, obscurus, p. 230, is Gmelin's species.

Genus Fulmarus instituted, p. 233.

Fulmarus antarcticus, Steph. p. 2313, is based upon Proc. glacialisY&r. B. Lath.
Ind. Orn. ii. p. 823, ( = Var. A. sp. 9, p. 405, of Lath. Gen. Syn.) which is
the Thalassoica glacialoides. This synonym of the species was accidently
omitted in my paper on the Fulmarese, and the omission not discovered until
too late.

Genus Daption instituted, p. 239, with capensis as type. The author "ven-
tures to attach the numerous Southern Petrels described by Latham thereto,"
producing a heterogeneous assemblage in which figure antarctica, nivea. deso-
lata, gelida, grisea, (of Linn^nec Kuhl, Schl.) alba, and fuliginosa ( = Latham's
Otaheite species.)

Genus Pachyptila "111." adopted; under it are arranged,, besides its type
vittata (here called " Forstcri") ccerulea Gm., marina Lath., fregata Linn, and
furcata Gm., nearly all of which are typical of distinct genera.

Joan. Rein. Forster, Descr. Anim. etc. curante Henr. Lichtenstein. (1841.)

The numerous species described and named by Forster have an important
bearing upon the bibliography of the Family. It is greatly to be regretted
that they were only published at a comparatively recent date: and that his
figures still remain inedited. Forster appears to have had very little regard
for priority in the matter of names ; but his descriptions are in the main so
excellent, that nearly all his species are identifiable. The following is a list
of the species given by him :

Proc. capensis, p. 20.

Proc, vittata, p. 21.

1'roc. fuliginosa, p. 23. = Proc. atlantica Gould. = Plerodroma atlantica Bp.
= JEstrelata fuliginosa of my paper. Not of Gm. Lath. Vieill. Not of

throughout conducted, with the sole desire of elucidating truth. Should the
undertaking prove a failure, and the meagre results incommensurate with

Observations upon the Cranial Forms of the American Aborigines, based npon

Specimens contained in the Collection of the Academy of Natural

Sciences of Philadelphia.

BY J. AITKEN MEIGS, M. D.

The early record of every science abounds in crude facts, imperfect obser-
vations, and, consequently, in generalizations so hastily formed as to partake
more of the character of mere speculation than of strictly logical deduction.
These erroneous statements and premature generalizations are at first gene-
rally accepted as scientific truths. A few cautious observers, it is true, may
withhold from them their assent, but their opinions find no support beyond
themselves, until these facts and hypotheses come in conflict with others bet-
ter known and better established, or, are employed in developing still higher
and more comprehensive theories. Then, for the first time, they are subjected
to a rigid investigation, and their true value, at length, ascertained. Nowhere
can we find a more instructive example of this assertion than in the doctrine
which ascribes to the American aborigines a homogeneous cranial type.
For the philosophical ethnologist this doctrine is full of interest. If the

physical, and more especially the cranial, characteristics of the native
races of the New World are at once common and peculiar to them, it is strong-,
presumptive evidence that they are isolated or distinct from the rest of man-
kind in origin. If, on the contrary, it can be shown that the skulls of these
people really belong to different, well-marked types or forms, which, if not
identical with, are, at least, the homoiocephalic representatives of those of
the Eastern Hemisphere, it becomes very probable that there is for the Ameri-
can variety of man neither unity nor genetic isolation. The discussion of the
origin and affiliations of this widely spread race has an important bearing
upon the higher and more complex question of the unity of the entire human
family. As this discussion involves, among other facts, the consideration of
the osteological characters of the aboriginal American, it becomes very im-
portant to determine with exactitude the typical, cranial form or forms of this
race.

The extraordinary doctrine of a uniform American type of skull originated,
as is well known, with the late Dr. Samuel George Morton. He was also the
most enthusiastic and persistent advocate of this scientific dogma. A variety
of circumstances combined to give unusual acceptance to his views. He be-
gan his craniographic researches two years after the completion of Blumen-
bach's Decades Craniorum, by accumulating what was then, as far as I can
learn, the largest and most diversified collection of human skulls in the world.
These he long and attentively studied, until he acquired the right to speak
authoritatively concerning them. No one was in possession of so many na-
tive American crania as he, and so little interest was manifested in human
craniography at that time, that but few if any persons ever examined his col-
lection with the object of testing the validity of his conclusions. Moreover,
prior to the publication of Crania Americana, Dr. Morton had already acquired
the double reputation of a naturalist and a physician, and for several years
before his death occupied the most prominent, official position in the Acade-
my of Natural Sciences. In view of these facts, it is not at all surprising
that his opinions, instead of being controverted, as they now are, found ready
adherents ; and that one of the most eminent of living naturalists should have
employed them, as well established facts, in his attempt "to show that the
boundaries, within which the different natural combinations of animals are
known to be circumscribed upon the surface of our earth, coincide with the
natural range of distinct types of man."*

In 1856, while preparing for publication an article on the cranial charac-
teristics of the various races of menf I especially directed my attention to
those groups of crania in the Academy's collection which had not been de-
scribed by Dr. Morton. With regard to American and Egyptian skulls, which
he had so long and so carefully studied, I contented myself with reproducing
the conclusions which he had already published, my object being to exhibit
in general panoramic review the skull-forms of the human family. In the
concluding remarks of that article I observed that just as "the Kalmuck or
true Mongolian, the Tartar, Chinese, Japanese and Turkish types of skull are
all, to a certain extent, related, and yet are all readily distinguishable from
each other, and as each of these groups again presents several cranial varie-
ties ; so, among the barbarous aborigines of North America, notwithstanding
the general osteologic assimilation of their crania, important tribal distinc-
tions can be readily pointed out." I also remarked: " It is a general and
very well known fact — first noticed by Buffon— that the fauna and flora of the
Old World are not specifically identical with the fauna and flora of the New.
Their relationship is manifested in an interesting system of representation,
or as Schouw expresses it, of geographical repetition according to climate.
To a certain extent, human cranial forms appear also to fall within the limits

of this system. As far as my own opportunities for examination have gone,
I have not been able to find a single aboriginal American type of skull which,
in all its essential details, could be regarded as strictly identical with any in
Europe, Asia, Africa or Australia," " The massive, heavy skulls of northern
temperate Asia and Europe are represented in America by those of the Bar-
barous tribes — decidedly different, but allied forms. So the comparatively
small-headed Peruvians represent the equally small-headed Hindoos."*

In 1859, while attempting to determine the ethnic type of a singularly de-
formed skull from Jerusalem,! by comparing it with other crania, I noticed,
for the first time, how much the form of the occiput differed in the various
tribes of Indians. I also observed that "upon our side of the Atlantic the
Swedish crania find their representatives in the Arickaree Indian skulls."
Subsequently, in another paper, published in the Proceedings of the Academy ,\ I
endeavored to show that the conformation of the occiput varied as much among
the aboriginal American races as among the natives of the Old World. I pro-
pose now to demonstrate that this diversity'is not confined to the occipital re-
gion only, but is exhibited by the skull as a whole. Before, however, interroga-
ting upon this point the magnificent collection which science owes to the untir-
ing industry and sagacity of Dr. Morton, it becomes necessary to inquire for
a moment how this eminent craniographer was led to adopt the singular con-
clusions which he has given to the world in Crania Americana and subse-
quent publications.

It is well known that, with few but important exceptions, the earlier trav-
ellers who visited the New World, and certain historians also, speak decided-
ly of the general resemblance which pervades the aboriginal American tribes.
Their uniformity of aspect, customs, &c, led Herrera to assign to them a com-
mon origin§. "Whoever," said Don Antonio Ulloa, "has seen an Indian of
whatever region may say that he has seen them all."|| Bernard Romans was
" firmly of the opinion that God created an original man and woman in Ame-
rica of different species from any in other parts of the earth. "*[ Robertson
declared that all the inhabitants of America, except the Esquimaux, " must
be pronounced to be descended from one source."** Malte Brun thought
"that the Americans, whatever their origin may be, constitute, in the present
day, by their physical characters, not less than by their peculiar idiom, a race
essentially different from the rest of mankind. "ff In conformity with this
view he placed them alone in the last of the sixteen races into which he di-

formly assigned the American family to a separate group or class. Others
again, like Zimmerman,* Yirey,f Humboldt, J Garnot.$ and various au-
thorities of a still more recent date, associate the aboriginal Americans
with the Mongols or other Asiatics. It is an interesting fact that Cuvier ||
recognized three distinct races of man, into neither of which, however, did he
place the Americans, but left them unclassified.

The statements of the earlier investigators — those of the sixteenth and
seventeenth centuries — concerning the -similarity of physical characters ex-
hibited by the different sections of the American race, harmonize remarkably
with the results of the laborious and protracted researches of different emi-
nent philologists. As early as 1798, Dr. Barton endeavored to show " that in
all the vast countries of America, there is but one language.''^ In 1810, the
celebrated philologue, Yater, to whom had been committed the completion of
Adelung's Mithridates, or Allgemeine Sprachenkunde showed that the general in-
ternal or grammatical structure of the American languages was the same for
all.** Humboldt, in his Personal Narrative, testified to the same remarkable
phenomenon.! f Du Ponceau characterized the peculiar, complicated grammar
of the American idioms from Greenland to Cape Horn by the term polysyn-
thetic.JJ Still later. Gallatin affirmed that all the languages of the native in-
habitants of America from the Arctic Ocean to Gape Horn, have, as far as they
have been investigated, a distinct character common to all, and apparently
differing from any of those of the other continent with which we are most
familiar. \\

While these and other observers were thus surveying the American Races
from a philological standpoint, the late Dr. Morton was industriously en-
gaged in collecting the materials necessary to illustrate their osteology, and
at the same time the distinguished French naturalist, M. Alcide D'Orbigny
was travelling in South America and studying the natives, not with the un-
practised and superficial eye of the curious traveller, but with that of the
closely observant and discriminating anatomist.

The remarkably discrepant ethnological results of the labors of these emi-
nent naturalists were given to the world at the same time. The Crania Ame-
ricana and LI Homme Americain both appeared in the year 1839. In the former
work, Dr. Morton, speaking of the native Americans, declared that "it may
be assumed as a fact that no other race of men maintains such a striking
analogy through all its subdivisions, and amidst all its variety of physical
circumstances."! In a later publication he asserted that " the peculiar phy-
siognomy of the Indian is as undeviatingly characteristic as that of the Ne-
gro ; for whether we see him in the athletic Charib or the stunted Chayma, in
the dark Californian or the fair Borroa. he is an Indian still, and cannot be
mistaken for a being of any other race.,;f \ On the other hand, M. D'Orbigny
affirmed, with equal emphasis, that " a Peruvian is more different from a Pa-
tagonian, and a Patagonian from a Guarani than is a Greek from an Ethio-

pian or a Mongolian."* This language sounds like the echo of the words of
Molina and of Humboldt. " I laugh in my sleeve," said the former, " when
I read in certain modern writers, supposed to be diligent observers, that all
the Americans have the same appearance, and that when a man has seen
one, he may say that he has seen them all." "A Chilian does not differ less
in aspect from a Peruvian, than an Italian from a German. I have seen
myself Paraguaynos, Cujanos and Magellanos, all of whom have their pecu-
liar lineaments which are easily distinguished from those of the others. "f
And Humboldt, too, an eye witness like Molina and D'Orbigny, tells us "that
those Europeans who have sailed on the great rivers Orinoco and Amazon,
and have had occasion to see a great number of tribes assembled under the
monastical hierarchy in the missions, must have observed that the American
race contains nations whose features differ as essentially from one another,
as the numerous varieties of the race of Caucasus, the Circassians, Moors and
Persians, differ from one another." " What a difference between the figure,
physiognomy, and physical constitution of the tall Charibs, who ought to be
accounted one of the most robust nations on the face of the earth, and the
squat bodies of the Chayma Indians of the province of Cumana. What a
difference of form between the Indians of Tlascala and the Lipans and the
Chichimecs of the northern part of Mexico. "J

Blumenbach recorded his conviction that "in the American variety of
mankind, as in others, countenances of all sorts occur. "$ Both Lawrence||
and Prichard, also distinctly recognized the differences exhibited by the abo-
riginal Americans.

" Perhaps the degree of resemblance to a common type subsisting between
the nations of America," says Prichard, " may admit of comparison with
that which is to be traced between the different nations of Europe or among
the races of Africa, or those of the northeastern parts of Asia. It is not
universally prevalent in the same degree, but there appears to be in every in-
stance some approximation to it; yet there can be no doubt tbat the resem-
blance has been in general much exaggerated. It will be easy to prove that
the American races, instead of displaying an uniformity of color in all cli-
mates, show nearly as great a variety in this respect as the nations of the old
continent; that there are among them white races with a florid complexion
inhabiting temperate regions, and tribes black or of very dark hue in low and
intertropical countries, that their stature, figure and countenances are almost
equally diversified." " The nations of South America have in general flatter
faces, and many of them a shorter and broader shape of body than the North
Americans. In these respects the southern people are more like the Tura-
nian nations than the northern tribes."^"

In another work he remarks : "Anatomists have distinguished what they
termed the American form of the human skull; they were led into this mis-
take by regarding the strongly marked characteristics of some particular
tribes as universal. The American nations are spread over a vast space, and
live in different climates, and the shape of their heads is different in different
parts."**

According to Dr. Barton, a writer named Postel "is said to have been the
first ' who made such a difference between the two Americas, by means of the
Isthmus of Panama, that the inhabitants of those two continents have no-

thing common in their origin.' "* The Abbe Clavigero entertained a similar
idea.f

Such, in brief terms, were the conflicting statements promulgated by differ-
ent writers prior to the publication of Crania Americana. With all these Dr.
Morton was thoroughly conversant. Through Cardan he knew that the skulls
of the inhabitants of the old Portus Provincire were square and deficient in
the occiput, that Charlevoix described the heads of one of the Indian nations
of Canada as globular, and those of another as flat ;J that De Pauw speaks
of certain Indians on the borders of the Maragnon having square or cubical
heads, | and that Malte Brun described the aboriginal Americans as having,
among other characters, " heads of a square shape, with the occipital bone
not so convey, and the facial line more inclined than among the Mongol
race." | He knew that Humboldt had declared in his Researches "that the
nations of America, except those which border on the polar circle, form a
single race characterized by the formation of the skull," &c/[ He was fa-
miliar also with the statements of Von Spix and Martius that the Brazilians
resembled the Chinese in possessing, among other physical characters, " a
small, not oblong, but roundish, angular, rather pointed head, with a
broad crown, prominent sinus frontales, low forehead, and pointed and
prominent cheek-bones."** He was also acquainted with the fact that both
Desmoulins and Bory de St. Vincent ascribed to a number of the American
races a spherical head as a prominent characteristic. Among the earlier
specimens added to his subsequently famous cranial collection, were some
brachycephalic skulls, with truncated or more or less vertically flattened oc-
ciputs, ff These, together with the numerous short-headed Peruvian crania
in his cabinet, presented such a striking contrast with the ordinary elongated
head-forms of the human family in general, that he was hastily led to regard
the short, round or angular skull with flat occiput and depressed forehead, as
the typical cranial form of the aboriginal Americans. This form he proba-
bly regarded as the osteological analogue to the holophrastic or polysynthetic
character which the philologist had already declared to be at once common
and peculiar to the American races.

Dr. Morton divided the American race into two great families — the Toltecau
and the Barbarous Tribes. The latter he subdivided into the Appalachian,
Brazilian, Patagonian and Fuegian branches. To the Appalachians he as-
cribed a rounded head ; large, salient and aquiline nose ; dark brown eyes,
with little or no obliquity of position; large and straight mouth ; nearly ver-
tical teeth and triangular face. They included all the nations of North Ame-
rica excepting the Mexicans, together with the tribes north of the river Ama-
zon, and east of the Andes. The Brazilian brancji, located between the riv-
ers Amazon and La Plata, and between the Andes and the Atlantic, embraced
the whole of Brazil and Paraguay north of the 35th degree of south latitude.
The Patagonian branch included the nations south of the La Plata to the Straits
of Magellan and the mountain tribes of Chili. The Fuegian branch comprised
the people who inhabit the island of Terra del Fuego, often called Patago-
nians. The Esquimau or Polar Tribes, Dr. Morton separated entirely from
the American race, and designated them " Mongol Americans."

With regard to the aboriginal American crania, Dr. Morton tells us that
" after examining a great number of skulls, he found that the nations east of

the Alleghany Mountains, together with the cognate tribes, have the head
more elongated than any other Americans. This remark applies especially
to the great Lenape stock, the Iroquois and the Cherokees. To the west of
the Mississippi, we again meet with the elongated head in the Mandans, Ri-
caras, Assinaboins, and some other tribes. Yet even in these instances, the
characteristic truncation of the occiput is more or less obvious, while many
nations east of the Rocky Mountains have the rounded head so characteristic
of the race, as the Osages, Ottoes, Missouris, Dacotas and numerous others.
The same conformation is common in Florida ; but some of these nations are
evidently of the Toltecan family, as both their characters and traditions tes-
tify. The head of the Charibs, as well of the Antilles as of Terra Firma, are
also naturally rounded ; and we trace this character, so far as we have had
opportunity for examination, through the nations east of the Andes, the Pa-
tagonians and the tribes of Chili. In fact, the flatness of the occipital portion
of the cranium will probably be found to characterize a greater or less num-
ber of individuals in every existing tribe, from Terra del Fuego to the Cana-
das."*

At a meeting of the Academy of Natural Sciences held June 1st, 1841, Dr.
Morton, in the course of some remarks upon the ancient Peruvians, again
speaks of "the squared or spheroidal form as characteristic of the American
race and especially of the Peruvians."! At another sitting of the Academy,
which took place on the 6th of July in the same year, he made some obser-
vations on eight Mexican skulls, and directed attention to the "high vertex,
flat occiput, great lateral diameter and broad faces" of these crania as char-
acteristic features of the aboriginal Americans. "Whoever will beat the
pains," he said on that occasion, " to compare this series of skulls with those
from the barbarous tribes, will, I think, agree that the facts thus derived from
organic characters, corroborate the position I have long maintained, that all
the American nations, excepting the polar tribes, are of one race and one spe-
cies, but of two great families, which resemble each other in physical, but
differ in intellectual characters. "J

These opinions Dr. Morton continued to reiterate, from time to time, at va-
rious meetings of the Academy. \ On the 27th of April, 1842, he read at the
Annual Meeting of the Boston Society of Natural History, An Inquiry into the
Distinctive Charateristics of the Aboriginal Race of America. In this paper he
contends still more emphatically for his favorite doctrine of the unity of the
American nations. After alluding to the color and stature of these people, he
says, " The same conformity of organization is not less obvious in their osteo-
logical structure, as seen in the squared or rounded head, the flattened or
vertical occiput, the high cheek bones, the ponderous maxillae, the large
quadrangular orbits, and the low, receding forehead. I have had opportunity
to compare nearly four hundred crania derived from tribes inhabiting almost
every region of both Americas, and have been astonished to find how the
preceding characters, in greater or less degree, pervade them all. This re-
mark is equally applicable to the ancient and modern nations of our conti-
nent ; for the oldest skulls from the Peruvian cemeteries, the tombs of Mexico
and the mounds of our own country, are of the same type as the heads of the
most savage existing tribes. Their physical organization proves the origin
of one to have been equally the origin of all."

In this paper Dr. Morton objects to the observations of Molina and Hum-
boldt, above referred to, in disproof of this pervading uniformity of physical
characters, by saying that the different people mentioned by these writers are
really of one and the same race, and readily recognized as such, notwithstand-

ing their differences of feature and complexion; and the American nations,
he thinks, present a precisely parallel case. But this objection, which is far
from being a valid one, can by no possibility be urged against the analogous
remarks of M. D'Orbigny.

Tn 184G, Dr. Morton contributed to the American Journal of Sciences,* Some
Observations on the Ethnography and Archceology of the American Aborigines, in
which he "avers that sixteen years of almost daily comparisons have only
confirmed him in the conclusions announced in his Crania Americana, that
all the American nations, excepting the Esquimaux, are of one race, and that
this race is peculiar and distinct from all others. The first of these propo-
sitions may be regarded as an axiom in Ethnography ; the second still gives
rise to a diversity of opinions, of which the most prevalent is that which
would merge the American race in the Mongolian."

In the same year he published An account of his Craniological Collection ; with
remarks on the Classification of some Families of the Human Race, in the form of a
letter, addressed to Mr. JohnR. Bartlett, Secretary of the American Ethnologi-
cal Society.f ^n tu's letter he thus writes :

" The anatomical facts, considered in conjunction with every other species
of evidence to which I have had access, lead me to regard all the American
nations, excepting the Esquimaux, as people of one great race or group. From
Cape Horn to Canada, from ocean to ocean, they present a common type of
physical organization, and a not less remarkable similarity of moral and men-
tal endowments which appear to isolate them from the rest of mankind ; and
we have yet to discover the unequivocal links that connect them with the
people of the old world."

Dr. Morton's last contribution to craniographical science, J which was
published after his death, shows conclusively that his views respecting the
homogeneity of the aboriginal American races had undergone no change
whatever. In this paper he still maintains the doctrine of a uniform, cranial
type for these races, with the same arguments and in language almost iden-
tical with that which he employed in his Inquiry ten years before.

I make these references to his published opinious to show that Dr. Morton
perseveringly inculcated this doctrine from the inception to the very close of
his ethnological studies, comprising a period of about twenty-one years ;
that he was thoroughly convinced of its truthfulness, and regarded it as one
of the best established and most readily demonstrable of all the conclusions
at which he had arrived after a long and unwearied study of his cranial
collection.

It is a remarkable fact, however, that opinions diametrically opposed to
these were maintained by two French ethnologists, with whose writings Dr.
Morton was familiar, and whose classifications he criticises adversely in Crania
Americana.^ I allude to Dr. Desmoulins and M. Bory de St. Vincent.

As far back as 1826 Desmoulins divided the aboriginal Americans into two
species, — the Columbians and the Americans. To the first he assigned as
their chief specific character an "elongated head," and to the second " a
generally spherical head." The Columbians occupied the whole of North
America, all the table lands and declivities of the Cordilleras, from Chili to
Cumaua, and also the Caribbean archipelago. The Americans comprised the
Omaguas, Gauranis, Coroados, Puris, Atures, Ottomacs, Botocudos. Guiacas,
Mbayas, Charruas, Puelches, and Tehulletts or Patagonians. "There is no
doubt," says Desmoulins, " that the Columbians, and still more the Ameri-
cans, are each again divisible into several species, as different from each other
as those of Africa. ||

Bory de St. Vincent divided the Americans into four species,— the Nep-
tunian, Columbian, American and Patagonian. Of the Columbians he says:
"Leur tete est bien conformee, il en resulte une figure agreablement ovale,
ou le front est cependant singuliereinent aplati ;" and of the Americans:
" Les hommes ont, a peu d'exception pres, la tete ronde, d'un volume dispro-
portionne, enfonc^e dans les epaules, lourde, aplatie sur le vertex," &c*

In 1839, M. D'Orbigny, speaking of the native races of South America, de-
clared that, after examining a large number of crania, he was convinced that
they differed from each other not only according to race and nation, but also
individually; and that it would be as difficult to prove that the form of the
head is one among the Americans, as to demonstrate rigorously the perma-
nent cranial characters, which would be sufficient to distinguish them from
other nations. f

The late Prof. Retzius communicated to the meeting of the Scandinavian
Association of Naturalists, held at Stockholm, in 1842, a valuable paper on
the Form of the Skulls of Northerns, in which he refers the Greenlanders and
some of the American races to the prognathic Dolichocephali, and others of
the American family to the prognathic Brachycephali.J Two years later he
read before the same Association, at a meeting held in Christiania, in July,
1844, another essay On the Form of the Skull in different Nations,^ in which he
devotes a special section to the American races, and classifies tbem in the
following manner, according to the length of the cranium :

The latest and best elaborated views of Prof. Retzius upon this subject are
contained in a valuable essay, entitled A Glance at the present state of Ethnolo-
gy, with reference to the Form of the Skull.* This paper was read at the seventh
meeting of the Scandinavian Association of Naturalists, held at Christiania
in 1856. In it, the author thus criticises the theory of American unity, so
long and so persistently supported by Dr. Morton :

"No European philosopher has," says Prof. Retzius, " since the time of
Blumenbach, devoted such fertile labor to the subject of ethnological crani-
ology as Dr. Morton, of Philadelphia, in his ' Crania Americana;' the results
of which are, nevertheless, but little satisfactory. Morton, himself, who has
brought forward so many facts of high value, has, like the distinguished
linguist who with such indefatigable labor studied the American tongues,
come mainly to the conclusion that both the race and the language are one.
I am rather perplexed as to this result, for I must confess that, from the facts
brought forward by Morton, and the numerous skulls with which he has so
kindly enricked tke collections in Stockholm, I have arrived at a wholly dif-
ferent inference. I can explain this only by supposing that this distinguished
man has allowed his extensive philology and great learning to affect his
vision as a naturalist. If the form of the skull is to have any weight in the
question of the races of man, there is scarcely any part of the world where
such contrasts are to be found between dolichocephali and brachycephali as in
America, and as such they present themselves to the eye of the naturalist in
Morton's ' Crania Americana.' I may just refer, for proof of this, to plate 2,
' Peruvian child from Atacama ;' plate 32, ' Lenni Lenape ;' plate 38, ' Pawnee ;'
plate 40, ' Cotonay, Blackfoot ;' plate 64, ' Carib of Venezuela ;' plate 65, ' Ca-
rib of St. Vincent ' — all of the most marked dolichocephalic forms ; and, on the
other hand, to plates 30 and 31, 'Natches,' with the great majority of the
figures of skulls from Chili, Peru, Mexico and Oregon, with many others of
equally well marked brachycephalic form. Much as these plates bear the
same testimony, I should scarcely have ventured on such a remark, did not a
very rick series in our own collections, as well as several valuable drawings
by Blumenbach, Sandifort, Van der Hoeven, &c, support my opinion.

"From what I can infer from the American skulls I have seen, whether in
nature or in casts or plates, I have come to the conclusion that the dolicho-
cephalic is the predominant form in the Carribbee Islands, and in the eastern
region of the great American continent, from its most northern limit down
to Paraguay and Uraguay; and the brachycephalic in the Kurile Islands and
on the continent, from Behring's Strait, in Russian America, Oregon, Mexico,
Ecuador in Peru, Bolivia, Chili, Argentina, Patagonia, and Terra del Fuego.

"Morton has also drawings of four Esquimau skulls, from the most north-
ern parts of America, and from the island of Disco, off the coast of Greenland ;
all of the characteristic form. In the text he says that they are always
characteristic, and that they are most decidedly distinguished from the skulls
of tke American Indians ; but adds at the same time, singularly enough, that
these Esquimaux are the only Americans presenting the Asiatic characters.
It is evident that this distinguished man has been guided by his already es-

see that it contains some views of, as I think, great importance ; as in the question of the unity of
the American races, which I have clearly shown false." This letter appears to have been written
not long before the death of this eminent Swedish craniographer.

tablished views, rather than by the strict investigation of facts. He saw in
the formation of the face of the Esquimaux, something Mongolian, that is,
Asiatic ; but he overlooked the prominent occiputs, as well as other charac-
ters which are not Mongolian. In like manner he, as it were, forgot the
beautiful figures given by himself, in his splendid work of dolichocephalic
American Indians; of which some in particular, as Cotonay (Blackfoot),
Cherokee, Chippeway, and, above all, Cayuga (PI. 35), approach the form of
the Esquimau skull, with their large alveolar processes and projecting
occiputs."*

Prof. Retzius refers the aboriginal inhabitants of America to three distinct
sources. As certain Chinese skulls in the museum of the Carolinean Insti-
tute resemble Tungusian and Greenland crania, he traces the pedigree of the
Esquimaux into Asia, among the Chinese population, the transitionary link
being the Aleutians. The dolichocephalic Indians he assumes to be related
to the Guanches of the Canary Islands, and the Atlantic tribes in Africa, as
the Moors, Berbers, Tuaricks, Copts, &c, which are comprised under the
Amazirgh and Egyptian Atlantidas of Latham. The American brachycepba-
lic tribes, which belong chiefly to the side of America looking towards Asia,
the Pacific Ocean, and the South Sea, are allied, he thinks, to the Mongolian
nations, f

D'Omalius d'Halloy, in 1845, divided the American Indians into a northern
branch, characterized with " elongated heads," and a southern branch,
having "the head ordinarily less elongated."!

In 1846 Dr. Zeune, from a careful examination of the skulls in the anatomi-
cal collection at Berlin, adopted three main cranial forms or types for the
western hemisphere. He remarks that, although Blumenbach and Prichard
grouped the races of the New "World together as one, he found greater and
more marked differences among their skulls, than among those of the Old
World. I

In 1850 Dr. Latham endeavored to show, by means of a comparative table
constructed from Dr. Morton's own measurements, that the general ascription
of the brachycephalic form to the American Indians was an error ; and that,
on the contrary, they were more frequently dolichocephalic. ||

In the same year Dr. Knox also expressed a doubt as to the "asserted
identity of the Red Indian throughout the entire range of continental
America."^"

In 1848, Col. Chas. Hamilton Smith declared that "it is vain to assert that
all American Races, excepting the Esquimaux, have originally sprung from
one stock."**

In the years 1855 and 1856, we find three other ethnologists, in widely sepa-
rated localities, expressing their doubts, each from his own independent ob-
servations, as to the validity of Dr. Morton's long cherished views.

"The inspection of the Mexican skulls represented in Crania Americana,"
says Dr. Gosse, " seems to prove that in these the depression of the occiput
was far from being as general and as marked as among the Incas and the
crania examined by Meyen ; for in many of them the head is rather normally
developed behind. "ff

Dr. J. B. Davis also writes that though " this position of Morton's is no

doubt founded in truth, yet it must be allowed to be liable to numerous ex-
ceptions."*

In November, 1856, Prof. Wilson, of Canada, who, for some time before,
had been especially directing his attention to the conformation of the Ameri-
can Indian cranium, published an account of the discovery of some Indian
remains in Canada West.f "No indications," he wrote on that occasion,
"have yet been noticed of a race in Canada corresponding to the brachyce-
phalic or square-headed mound-builders of the Mississippi, although such an
approximation to that type undoubtedly prevails throughout this continent
as, to a considerable extent, to bear out the conclusions of Dr. Morton, that a
conformity of organization is obvious in the osteological structure of the
whole American population, extending from the southern Fuegians, to the
Indians skirting the Arctic Esquimaux. But such an approximation, — and it
is unquestionably no more, — still leaves open many important questions rela-
tive to the area and race of the ancient mound-builders. On our northern
shores of the great chain of lakes, crania of the more recent brachycephalic
type have unquestionably been repeatedly found in comparatively modern
native graves. Such, however, are the exceptions, and not the rule. The
prevailing type, so far as my present experience extends, presents a very
marked predominance of the longitudinal over the parietal and vertical di-
ameter ; while, even in the exceptional cases, the brachycephalic character-
istics fall far short of those so markedly distinguishing the ancient crania,
the distinctive features of which some observers have affirmed them to ex-
hibit."

In August, 1857, Dr. Wilson read before the meeting of the American Asso-
ciation for the Advancement of Science, a valuable and interesting paper on
the Supposed prevalence of one Cranial Type throughout. the American Aborigi-
nes. % In this article, the mere doubt expressed a year before now becomes a
positive conviction, that native American crania do not belong to one type, but
are referrible to dolichocephalic and brachycephalic forms; "and that a
marked difference distinguishes the northern tribes, now, or formerly occupy-
ing the Canadian area, in their cranial conformation, from that which pertains
to the aborigines of Central America and the southern valley of the Missis-
sippi ; and that in so far as the northern differ from the southern tribes, they
approximate more or less, in the points of divergence, to the characteristics
of the Esquimaux. " In the second edition of Prehistoric Man, published eight
years later, he concludes that "the results of his attempts at a comparative
analysis of the cranial characteristics of the American races show that the form
of the human skull is just as little constant among different tribes or races of
the New World as of the Old ; and that so far from any simple subdivision
into two or three groups sufficing for American craniology, there are abundant
traces of a tendency of development into the extremes of brachycephalic and
dolichocephalic forms, and again of the intermediate gradation by which the
one passes into the other. '§

It will thus be seen that Desmoulins, Bory de St. Vincent, Alcide d'Orbigny,
Retzius, D'Omalius d'Halloy, Latham, and, more recently, Wilson, have all
expressed their conviction, in terms more or less emphatic, that the American
races are divisible, according to the form of the skull, into dolichocephalic and
brachycephalic groups. Retzius and Zeune have gone a step further, by re-
ferring the crania of these races to three distinct forms or types. According
to Zeune, these crania are divisible into long, broad, and high forms, corres-

ponding to three similar types in the Old World ; and according to Retzius,
into Asiatic dolichocephalic, (Chinese,) Mongolian, and Semitic forms. Zeune,
in his comparative table, has indiscriminately grouped together normal and
artificially deformed skulls. His classification has, consequently, no ethno-
logic value. To Prof. Retzius is due the credit, as far as I can learn, and as
appears from the above chronological reference to the literature of this sub-
ject,— of being the first to perceive the true ethnological import of the data
set forth in Crania Americana. From 1842 to 1S60, the year of his death, he
as positively opposed the doctrine of aboriginal American unity as Dr. Morton
zealously supported it. Dr. Wilson has indisputably confirmed the views of
Retzius as to the division of the American tribes into long and short heads,
and their consequent cranial non-unity, by means of a valuable series of com-
parative tables of measurements, accompanied with important critical obser-
vations, showing very considerable, judicious, and even enthusiastic research.*
Like Humboldt and Pickering, he favors the Mongolian classification of the
American Indian, and thinks that this classification is " borne out by many
significant points of resemblance in form, color, texture of hair, and peculiar
customs and traits of character."!

From a careful examination of the Morton Collection, I am convinced that
the division of aboriginal American crania into dolichocephalic and brachy-
cephalic groups merely, is wholly inadequate to exhibit thoroughly the ethnic
differences which dispart them, in some instances, quite widely. It is easy
to point out crania which are comparatively shorter than most of the so-called
long skulls ; and others again, which are longer than the so-called short-heads.
Such deviations fall naturally into an intermediate or mesocephalic group,
which differs from the two extreme classes not in length only, but in other
characters also. Moreover, the ethnic value of dolichocephalism and brachy-
cephalism, or of length as compared with heighth and breadth, is by no means
fully determined. This character is not always of primary importance. On
the contrary, it is frequently of secondary value in classification. Two or
more skulls may be equally dolichocephalic, and yet belong to different types
or forms. Compare, for example, the cranium of the typical wooly-haired
negro represented on page 325 of Indigenous Races, with the skull of an
ancient Roman, or of a Circassian, figured on pages 312 and 316, respectively,
of the same work. These are all dolichocephalic ; but the slightest inspection
shows that they belong to very different types, and that the typical or differ-
ential characters are located in the facial bones chiefly. In like manner, if we
compare together the Ottawa and Mound skulls Nos. 1007 and 1512, which
are both brachycephalic, we readily perceive that the one belongs to the
spherical or globular form, and the other to the square-headed or cubical type.
In order to establish indisputably the cranial diversity of the American races,
it is obviously necessary, in view of the above facts, not only to point out

* In his paper, read before the American Association in 1857.— a year after Retzius had publicly
announced his matured views upon American crania to the Scandinavian Association, anil through
it to the scientific world generally — Dr. Wilson says: " Scarcely any point in relation to ethno-
graphic types is more generally accepted as a recognized postulate than the approximative homo-
genous cranial characteristics of the whole American race." "The stronghold of the argument
for the essential oneness of the whole tribes and nations of the American continents, is the sup-
posed uniformity of physiological, and especially of physiognomical and cranial characteristics: an
ethnical postulat" which has not yet. so far as I am aware, been called into question." (Canadian
Journal, Nov., 1857, pp. 409, 416.) When these lines were written, Dr. Wilson appeal not to
have been acquainted with the labors of Retzius in this field; he certainly makes no allusion
to them whatever. These statements are reproduced in 1862, in the first edition of his " Prehis-
toric Wan," (pp. 205, 212.) and again in 1866, in the second edition of this deeply interesting work,
(pp. 425, 430, 431.) In both these editions he alludes to Retzius simply as amongst those who
have recorded conclusions similar to his own. He refers the reader, for the views of Retzius. to the
" Archives rles Sciences Naturelles," published at Geneva in 1860, and, in his "Lectures on Physical
Ethnology," in the Smithsonian Report for 1862, p. 244, accompanies this reference with the state-
ment that his own views on this subject were first published by him at the meeting of the Ameri-
can Association in 1857.

among these races the prevalence of both dolichocephalic and brachycephalie
forms, but also to demonstrate the existence of different well-marked types
into which they may he grouped, and which can be shown to be as different
from each other as any of the distinct forms indigenous to the Old World.
This I have attempted to do in the ensuing pages, carefully abstaining, how-
ever, for the present, from the expression of any opinion concerning the allied
but entirely distinct question of the origin and affiliations of these races. As
this question, in its osteological aspects, is intimately connected with the con-
sideration of the cranial characters of the Esquimau race, I propose, instead
of discussing it at present, to return to it in a future monograph upon the
skulls of the Polar people.

The Human Cranial Collection of the Academy of Natural Sciences of Phila-
delphia, contains at the present time 575 skulls of the Aborigines of Northern,
Central and South America.

The Esquimau Family is represented by thirteen specimens from Baffin's
Bay, Storoe, Cape Alexander, Upernavick and Godhavn. Dr. I. I. Hays, on
his return from the Arctic regions in 1861, brought with him 125 skulls of this
race. This large and very important collection he kindly placed in my care
for study and description, with the request that I should select therefrom and
present to the Academy, as his donations, those specimens which appeared to
constitute the most suitable additions to the Museum.* Through these addi-
tions the Esquimau race, though occupying a region so remote and inacces-
sible, will be more numerously represented in the collection, than any of the
North American Indian tribes.

Of the great Athapascan or Chippewyan Family, lying to the south of the
Esquimau area, and extending from Hudson's Bay westwardly towards the
Pacific Ocean, there is but one specimen in the Museum of the Academy. This
skull, No. 577 of my Catalogue of Human Crania, belongs, moreover, to none
of the tribes living in juxtaposition within the continuous area of the Athapas-
cas, but to a small detached band, called Tlatskanai or Klatskauai,t living in
the mountains south of the Columbia River, near the sea-coast. This tribe,
now nearly, if not quite extinct, belongs to the " Tahkali-Umkwa Family " of
Hale, | which is synonymous with the " Southern Athabaskans " of Latham. §
It is thus classified on account of its philological affinities, which are Atha-
pascan.

It is obviously impossible to determine the craniological relations of the
Tlatskanai, and through these of the Athapascas generally, by means of the
single cranium just referred to. This skull is artificially distorted or com-
pressed like the Chinook crania. The longitudinal and bi-parietal diameters
are nearly equal. Art has, therefore, rendered it brachycephalie. The upper
alveolus is quadrangular in form.

To enumerate the various tribes of Athapascas of which cranial specimens
are wanting in the collection, would be to go over the entire list of these tribes
as now known. In view of the geographical position of this group, this is
much to be regretted. The Koluschians and Athapascans on the west of Hud-
son's Bay and the Algonquins on the east are the only Indians coterminous
with the Esquimaux. The Athapascan area borders upon the Esquimau re-
gion over a much greater extent of surface than that of either the Koluschians
or Algonquins. Among the Athapascas, the Coppermine, Dog-Rib and Hare
or Slave Indians come in contact with the Esquimaux as far north as the Arctic
circle. As they are thus exposed to the same climatic conditions it becomes
very important to compare the crania of these tribes with those of their para-
borean neighbors. The same remark applies to the northernmost of the Ko-

lusehian and Algonquin tribes. Unfortunately for the purpose of such com-
parison no specimens of the skulls of these tribes are in the possession of the
Academy. In other words the collection is deficient in skulls of the Kenai of
Cook's Inlet, the Atnahs of Copper River, the Ugalents or Ugalyakhmutzi, of
King William's Sound, &c, among the Koluschians ; and in the Knistinaux or
Crees, and the various other tribes of Algonquins who formerly occupied the
country between Labrador and the New England States.

The Indians of the north-west coast are represented in the collection by 22
specimens, obtained from various localities in British Columbia, Washington
Territory, and the State of Oregon. Three of the skulls of this series, a Tsitn-
se-ann or Chimseyan and two Nas-kuhs or Naaskoks (Nos. 987, 213 and 214
of tbe Catalogue), belong to the Naas family of Hale, and are from the Naas
River and tbe region of country about Fort Simpson, in lat. 54° 40' N. Con-
sequently of all the Pacific coast crania in the collection they are the most
northern. The Chimseyan skull is a long, low head with a moderately full
and rounded occiput. The coronal region is flat and triangular, narrow at the
forehead between the external angular processes, from which it widens out to
a great interparietal diameter, the parietal protuberances being very promi-
nent. Both the Naas crania are long, oval heads with full and prominent oc-
ciputs. In No. 213 the occipital protuberance is prolonged into a sharp mam-
millated process. The next six in geographical order, (Nos. 208, 944, 946,
1013, 1014 and 1015), are from Puget's Sound. No. 208 is the skull of a Skwale
or Nisqually "Medicine Man." It is artificially flattened. The other five
are flattened heads, obtained by my friend Dr. Thos. J. Turner, of the U. S.
Navy. They probably belong, with one exception, to the Suquimmish tribe.
These six crania together with a Kowalitsk skull, (No. 573) from Washington
Territory, and a Tilamook, Killemook or Killamuck cranium (No. 576) from
the State of Oregon, belong to the Tsihaili-Selish Family of Hales, the Tsihaili
of Latham. The next two crania of this group are Klikatats (Nos. 207* and
461) from Washington Territory. They belong to the Sahaptin Family of
Hale and Gallatin. Of the Calapooya or Kalapuya tribe of the Willamette
Valley, Oregon, there is one cranial specimen, No. 574. There are nine Chi-
nook crania in the collection. Of these Nos. 462, 641, 721, 1349 and 1350 are
Chinooks proper. Nos. 203 and 575 are Clatsops or Klaatsops, a band of the
lower division of Chinooks, occupying the sandy plain at Point Adams, to the
south of the mouth of Columbia River. Nos. 457 and 578 should, in all pro-
bability, be rejected from this series. As they are not flattened nor distorted
in any manner, but retain the natural form, they are very likely slaves, and
as such belong to some other tribes. All the free Chinooks flatten their heads,
and so highly do they value this deformity as a mark of distinction that they
do not allow their slaves to practise it.

Upon this point most of the travellers who have visited the tribes of Colum-
bia River agree. In other respects, however, their testimony is very discrep-
ant. Mr. Townsend, in a letter to Dr. Morton, affirms that he " has occasionally
seen both Chinooks and Chickitats with round or ordinary shaped heads, sick-
ness having prevented the usual distortion while young."f This statement
has evidently led Dr. Morton to regard No. 578 as a true Chinook skull which
has not been subjected to the flattening process. " This head," says Dr. M.,
" differs in nothing from that of the Indians in general, from one end of the con-
tinent to the other ; but it is gratifying to be able to present a perfectly natu-
ral skull of people among whom a round or naturally formed head is consid-
ered a degradation."! Dr. Pickering assures us that as the children, whose
heads have been compressed, "grow up, the cranium tends to resume its

natural shape, so that the majority of grown persons hardly manifest the ex-
istence of the practice. One effect, however, seemed to be permanently dis-
tinguishable, in the unusual breadth of face."* Mr. Hale also says: "In
after years the skull, as it increases, returns in some degree to its natural
shape, and the deformity, though always sufficiently remarkable, is less shock-
ing than at first. "f Dr. Pickering declares "that slaves may in general be
distinguished by the head not being flattened, though they are careful to per-
form this process on their children. "J Mr. Hale, on the contrary, states that
" the children of slaves are not considered of sufficient importance to undergo
this operation, and their heads, therefore, retain their natural form." Mr.
George Gibbs, who dwelt for several years among the coast tribes iu the capa-
city of Indian agent, likewise declares that " the children of slaves are not
allowed to flatten the skull. "§ In another place he says, "among some of
the Pacific tribes, compression of the head is confined to females, or is, at any
rate, only carried to any considerable extent among them. Slaves are some-
times of the same tribe with their owners, but they are more frequently pur-
chased from others ; and it should be noted that on the Pacific the course of
the trade has been from south to north. "|| This gentleman, in an interesting
letter to the writer, dated July 8th, 1850, suggests that " as slaves very rarely
if ever spring from the tribes in which they are held, and as the course of the
slave trade is almost always from the south to the north," the two skulls
above referred to, Nos. 457 and 578 most probably come from southern Oregon
or California. The Klamath and Shaste tribes of California, he thinks, fur-
nish many slaves to the region about Fort Vancouver, while captives from
this region are taken still further northward from Puget's Sound as far north
even as the Russian possessions. In opposition to these statements of
Mr. Gibbs, we are informed by Mr. Townsend that among the Chinooks
those individuals whose skulls were not flattened during infancy, on ac-
count of sickness, "never attain to any influence, nor rise to any digni-
ty in their tribe, and are not unfrequently sold as slaves." Mr. Jas. G.
Swan, in his account of the coast tribes between the Straits of Fuca and the
Columbia River, says, "their slaves are purchased from the northern Indians,
and are either stolen or captives of war, and were regularly brought down and
sold to the southern tribes. "H" My friend Dr. Thos. J. Turner, U. S. N., who
spent some time at Puget's Sound, in 1856, and whom I therefore interrogated
upon this subject, informs me that there is a marked distinction between the
Indian tribes on Vancouver's Island and to the north of the Straits of Fuca,
and those on the southern side. The northern tribes known as Stikanes, or
Cowitchins, are taller, more war-like, and of a lighter color than the southern
Indians, and what is very remarkable, have been seen by him to blush.** In-
stead of compressing their heads into a disc-like shape, as the Chinooks do,
they give to them, by means of bandages, a conical or sugar-loaf form. Fur-
ther north this custom is discontinued by the men, and is confined altogether
to females. Dr. Turner also informs me that unaltered heads, found among
tribes addicted to this practice to a great degree, may safely be assumed to be
those of slaves, and are probably of foreign origin, either directly or ancestrally.
The direction of the slave trade is northward. On this account the southern
tribes are always in fear of their more aggressive northern neighbors. As the

flattened head in all its varieties is considered a mark of distinction among
these people, tliey are very loth to abandon it. In several instances, where
the "papooses" came under medical treatment, efforts were made to induce
the mothers to discontinue the practice, but without avail.

These conflicting statements show how difficult it is to determine satisfac-
torily whether Nos. 457 and 578 are Chinooks or not. The latter somewhat
resembles the Naas skull, No. 214, but is comparatively shorter and broader.
The former is more like the Chimseyan. If they are really Chinooks, it shows
that these people are naturally dolichocephalic. Judging from the deformed
specimens, I should suppose the heads of the Chinooks were naturally short
or brachycephalic. The unflattened Chinook, No. 578, is a rather short, broad
oval, having the vertex regularly and more highly arehed, and the occipital
region less promiuent, rather flatter in fact, than is the case in the Arickaree
and Assinaboin crania. No. 457 approaches the peculiar form exhibited in a
Pocasset skull, presently to be referred to.

Upon a careful examination of all the cranial specimens of these fiat-head
tribes of the Columbia River, I find that the distortion is not alike in all. In
Nos. 203, 207, 208, 461, 577, 641, 721, 946, 1013, 1014 and 1349 the compres-
sion has been so applied as to cause the right half of the occipital region to
be more flattened than the left, and, consequently, the antero-posterior diam-
eter of the right side to be shorter than the left. In Nos. 574 and 575 the
distortion is just reversed. Nos. 462, 573, 576 and 944 are almost symmetri-
cally flattened, and in such a manner that the coronal region forms a horizon-
tal plane parallel with the basis cranii. In the Kawichen skull, No. 1015, the
pressure has been so applied as to give to it the form of a cone or sugar-loaf,
causing it thereby to resemble very strongly the strangely deformed Natchez
crania, and the Mound Skull, No. 1212, from the ancient town of Chiuchiu,
near the Desert of Atacama.

Three crania recorded in the third edition of Dr. Morton's Catalogue of
Skulls, as belonging to " Cotonay or Blackfoot Indians,"* differ from each
other sufficiently to justify the reference of them to two separate groups.
While Nos. 744, a male skull, and 745, a female, are decidedly dolichocephalic,
No. 1227, the head of a chief named the Bloody-Hand, from the upper Mis-
souri, occupies an intermediate place between the long and short heads. It
is a shorter, broader and more elevated or arched cranium. In Nos. 744 and
745 the occipital region exhibits the superiorly inclined or shelving parieto-
occipital flatness so characteristic of Swedish and Norwegian crania. The
occipital flatness of No. 1227 is less inclined and more vertical. In the length
of skull, prominence of occiput, and general shape of the coronal region, No.

744 resembles the cast of a Norwegian skull, No. 1260, which I have in an-
other place already briefly described. The receding forehead, strongly marked
supraorbital ridges, and everted upper alveolus of the Kootenay cranium,
however, serve to distinguish it from the Norwegian. In general form No.

745 resembles the Arikaree type, as that type or form is displayed in No. 619.
No. 1227, in the general outline of the coronal region and flatness of the occi-
put, resembles the short-headed Germanic and Anglo-Saxon forms. On the
other hand, the strongly-marked face, the deep, massive jaw and prominent
maxillary alveoli of this skull are striking points of difference. In Crania
Americana, plate 40, Dr. Morton figures a Kootenay skull loaned to him by
Geo. Combe, the celebrated phrenologist. It is decidedly dolichocephalic.
Dr. M. has cuven us no description of this head, but merely alludes to its
great interparietal breadth. I am inclined to think that No. 741 is really the
cranium from which this plate was drawn. There is not only a close resem-
blance in the outlines of the two, but in the skull there is a hole in the

middle of the right parietal bone, just above the tuberosity, exactly as repre-
sented in the plate. A comparison of this plate with the wood-cut of No. 1227,
in the Catalogue of Human Crania, and also in Indigenous Races, is sufficient
to show that in this group of three skulls two distinct forms exist. No. 744
may be assigned to the kumbecephalic, and No. 745 to the narrow oval sub-
divisions of the oval form or type. Both have flat and receding foreheads run-
ning up to a higher point at the junction of the sagittal and coronal sutures
or just behind this point. No. 1227 falls into the arched type.

To the isolated or unplaced family of the Kitunaha, Coutanies or Kootenays,
therefore I provisionally refer Nos. 744 and 745 ; and to the Satsika or Black-
foot branch of the Algonquins, No. 1227.

To the east of the Blackfoot country, and extending from the Saskachawan
River on the north southwardly to the Arkansas River, and from the Missis-
sippi to the Rocky Mountains, lies an important ethnological region occupied
by the Dacota and Pawnee Families of Indians. The latter live in two sepa-
rate localities, surrounded in great part by the more numerous tribes of the
former.

Of the Pawnee group the collection of the Academy contains three Arikara,
and two Pawnee skulls. The Sioux or Dacota Family is represented by speci-
mens from eight different tribes, viz., Assinaboins, Minetaris, Mandans, Dako-
tas or Sioux's proper, Upsarookas or Crows, Osages, Ottoes, and the isolated
tribe of Winnebagos living on the western shore of Lake Michigan.

Three female Arickaree skulls from the upper Missouri, (Nos. 649, 949, 748)
belong to the dolichocephalic class. The coronal region in No. 64. » is oval
and rather flat, the vertical diameter, therefore, rather small ; the occipital
protuberance quite prominent, as in the Cimbric and Swedish crania in the
collection, and the upper half of the occipital region flat and shelving like
that of the Swedes ; the forehead low, superciliary ridges very small, malar
bones not very prominent ; ossa nas,i quite incurvated. The basis cranii of
No. 649 exhibits some approach to the kumbecephalic form of Prof. Wilson.
No. 949 exhibits the same general characters, but is fuller in the frontal re-
gion, and has a less prominent occipital protuberance. The same remarks
apply to No. 748. In the homoiocephalic comparison of the old and new
worlds, these Arickaree skulls may be fairly regarded as the American repre-
sentatives of the Swedish crania.

The two skulls in the collection marked Pawnee are remarkably discrepant
in form. One of them, No. 1043, is most probably an Arickaree cranium.
The other, No. 540, is a female head from the Platte River. It is figured in
Crania Americana, plate 38. In this skull the forehead is sufficiently de-
pressed, to cause the posterior part of the head to be higher than the anterior.
From the coronal suture, the median longitudinal line, coinciding with the
sagittal suture, curves regularly and evenly round to the upper edge of the
os occipitis. Hence the posterior region cannot be called flat, although at the
first glance it appears so, in consequence of the prominence of the occipital
boss. If the line of the crown is continued evenly to the base of the skull, so
as to cut off the occipital protuberance, it will then be seen that the posterior
region is full and round. This is not the case in No. 1043, also female, which
is^ longer head with a much more prominent occipital boss. The basis oc-
cipitis of this skull is flat, somewhat like that of the Minetaris, while the basis
cranii exhibits a long cimbriform outline instead of the round one presented
in No. 540. In fact No. 1043 resembles the Arickaree forms in many respects ;
and should, I think, be classified with this group. It differs from them, how-
ever, in such minor particulars as the form of the alveolar arch, breadth of
upper maxilla, &c.

To the dolichocephalic group must also be assigned the Minetaris or Gros-
ventres of Missouri. The oblong coronal region of the four cranial specimens
of this tribe in the collection resembles that of the Arickarees and Assina-
boins. The most elevated point of the crown is in the middle of the sagittal

suture, a little anterior to a line drawn through the parietalia from one emi-
nence to the other. The posterior region of the parietalia slopes downwards
and backwards to the irregular and lozenge-shaped occipital protuberance.
The basal portion of the occipital bone is remarkably flat. — nearly horizontal,
in fact, — and the cerebellar fossa? quite shallow. This peculiarity is well-marked
in all the specimens composing this group- This feature and the prominent
occiput give to the Minetari skull the appearance of being pinched or drawn
out behind. This is particularly the case in No. 746. The low crown, flat
sides and base of these skulls give them an angular, oblong or box-like ap-
pearance. The specimens of this group, three of which are females, and the
fourth a male, are remarkably alike.

Three Assinaboin skulls, also from the upper Missouri, (Nos. 659, 1230, 1231)
are larger than the Arickarees, as shown by their greater internal capacity.
They are more massive and roughly marked, and in general present more of
the rude Indian character. They are broader between the parietal bosses
than the Arickaree heads ; and, consequently, have a less narrow, and some-
what differently shaped coronal region. The contour of the latter slightly ap-
proximates the Germanic form. The occiput in No. 659, a male skull, is equally
protuberant, more massive and flat in the upper part, and the nasal bones less
incurvated than in the Arickarees. These features are not so well marked in
Nos. 1230 and 1231. It will thus be seen that No. 659 differs more from the
Arickarees than Nos. 1230 and 1231, but the two latter, like the Arickaree
specimens, belong to the female sex. Upon the whole, the base is not so long
and narrow.

The Mandans of the upper Missouri are a long-headed people. The general
form of their skulls resembles very closely that of the Arickarees and Assina-
boins. This is very well shown in Nos. 643, 644, 738 and 742 ; of which the
first three are females, and the last a male. In No. 739, a female skull, the
occipital protuberance is not so fully developed, but the posterior interparie-
tal diameter is greater. The coronal contour, consequently, undergoes some
change. In a male skull, No. 740, the broader coronal region is more oblong
than oval. In No. 741, also a male skull, the greater elevation of the breg-
matic region gives to that skull the arched or upsicephalic form presently to
be described. No. 738 closely resembles the Kootenay skull, No. 745.

No. 204, the skull of a Dacota or Sioux Indian, belongs to the Creek type,
as exhibited in No. 1454, though the occiput is a little more prominent, and
the head slightly longer and narrower. Its form is transitionary from the
broad oval of the Assinaboin skull. No. 112. the head of a Dacota child, is
markedly dolichocephalic, with an occipital region like a shelving roof. No.
605, the skull of a Dacota or Sioux Indian from Wisconsin, somewhat resem-
bles the Chetimache type, as the reader will perceive at a glance, by compar-
ing plates 19 and 39 of Crania Americana. The truncation of the occiput is
confined entirely to the upper part of the os occipitis and is but slightly marked.
Indeed the posterior region taken as a whole is full and rounded or globular
like that of the Pawnee skull, No. 540. These two heads, in fact, resemble
each other closely, so that it is difficult to say whether both be Pawnees or
both Dacotas. They certainly appear to belong to the same tribe. Dr. Mor-
ton speaks of having once seen in Philadelphia, in 1837, twenty-six chiefs
and braves of the Sioux nation. " Every man of them," says he, " bad a
broad face, high cheek bones, the large Roman nose expanded at the nostrils,
a wide but low forehead and flat occiput/'

The Osages are brachycephalic, as is particularly shown in No. 54, in which
the coronal region is almost round like that of the true Germanic head, and
the occiput perpendicularly flattened. This skull, which is that of a young
warrior named the Buffalo Toil, from Arkansas, is figured by Morton in Cra-
nia Americana, plate 41. The face is large and rude, the malar bones mas-
sive, and the alveoli prominent ; but the forehead is less recedent than in
many of the Indian crania. The skull belongs to the angularly round or

1866.]

216 PROCEEDINGS OF THE ACADEMY OP

square-headed Gothic type. No. 650, from the upper Missouri, is an older
and longer head, inclining rather to the Swedish form. It is not a Brachyce-
phalus, but occupies a position intermediate between the long and short heads.
The Ottoes of the upper Missouri belong partly to that intermediate form
which I have designated in the preceding pages as the arched type, and partly to
the short-headed groups. The oblong crown in No. 755 is considerably elevated
at the junction of the sagittal and coronal sutures. The occipital region is
full, broad and round, and not flattened. These skulls all incline to the brachy-
cephalic type. Indeed No. 756, which may be said to represent the Calmuck
form, and No. 758, should be classed among the short heads. No. 758, the
head of a young child, though longer, has a vertically flat occiput.

The Upsarookas or Crow Indians of the upper Missouri are long-heads. The
two skulls of this tribe in the collection are males, and resemble each other
very closely. They are long, oval crania ; the upper part of the occiput pro-
tuberant and lozenge-shaped ; the face long, the ossanasi high, and the depth
of the upper alveolus so considerable as to give a peculiar osteological expres-
sion to the face not easily described.

Of the Winnebagos, one, No. 559, is a short, angularly round head ; the
other, No. 560, is of an oblong form. In No. 559 the slight posterior flatness
is confined entirely to the upper part of the os occipitis. In No. 560 the oc-
ciput is more protuberant, and the base and crown longer than in No. 559.

Of the great and widely extended Algonquin Family, the Museum of the
Academy contains 79 skulls of 21 different tribes. These tribes are the Mas-
sasangas or Missiosigees, and the Chippewas of Upper Canada, the Penobscots
of Maine, the Mohegans of Connecticut, the Narragansetts and Pocassets of
Rhode Island, the Naumkeags of Massachusetts, the Naticks of Nantucket,
the Lenni-Lenapes or Delawares of New Jersey. Pennsylvania, &c. ; the Nan-
ticokes of the Wyoming Valley ; the Ottawas, Menominees and Pottawotomies
of Michigan ; the Sauks, Ottigamies and Illinois of Illinois and Wisconsin ; the
Miamis of Indiana ; the Skawnees and Mingos of Ohio ; the Shyennes of Mis-
souri, and the Blackfeet.

The Iroquois family is represented in the collection by 13 crania of Mo-
hawks, Oneidas, Senecas, Cayugas and Hurons. The former habitat of these
tribes was the country around and between Lakes Huron, Erie and Ontario,
in the heart of the Algonquin area. Of the southern Iroquois the collection
contains not a single specimen.

The Massasauga cranium, (No. 27,) of upper Canada, is a decidedly dolicho-
cephalic head with a protuberant occiput, a moderately elevated coronal re-
gion, and an oval base. In its general form it resembles the Arickaree
skulls.

The Penobscot skulls may also be classed with the Dolichocephali. They
are narrow and rather long, with a regularly oval crown. The occipital region
is rather narrow, but not flat, being smoothly rounded ; the elevation of the
crown about the middle of the sagittal suture, by increasing the vertical diam-
eter, slightly approximates this skull to the arched type. These remarks par-
ticularly apply to No. 89, an Indian of the Gepepscot tribe of Maine. No. 105
is very similar to it, but being fragmentary, and of uncertain locality, it need
not further occupy our attention.

A Mohegan or Mohican skull of the Quinnipiack tribe, (No. 26), is broad and
globular with a rounded occipital region. It occupies a position intermediate
between the long and short heads and approaches the Mongol form, as that
form is exhibited in the Calmuck, Cossack and Burat crania.

A Pocasset cranium (No. 1036) is comparatively short with a flattened oc-
ciput and triangular coronal region. It strongly resembles the Narragansett
head, No. 693, and should probably be grouped with this specimen.

The Narragansetts of Rhode Island are dolichocephalic. The ten skulls
representing this tribe in the collection are not equally elongated. On
the contrary, Nos. 693, (male,) 953, (female,) and 956, (male,) are much

[May,

NATURAL SCIENCES OF PHILADELPHIA. 217

shorter, and may be said almost to belong to the Brachycephali. No. 693, the
fnc simile of the Pocasset skull just referred to, is a peculiar head. The coro-
nal region is irregularly oblong ; the head widens out backwards from the os
frontis, attaining its greatest width between the parietal centres of ossification.
Moreover, the low receding forehead slants upwards to the same interparietal
diameter. The broad posterior region slopes downwards to the foramen mag-
num, as if pressed under the overhanging parietalia. Nos. 050, (female,) 951,
(male, ) 954, (female, ) 957 (male) and 1040, (female, ) are oblong heads, having
for the most part the superior occipital flattening seen in Swedish crania, and
also the protuberant occipital process, which is of the usual size and appear-
ance in Nos. 950 and 954, and forms a very large triangular knob in No. 951,
projecting in a straight line beyond the inferior and posterior edges of the
parietalia, as in the Swedish skull, No. 1249. In No. 957 the protuberance
disappears, or is very much softened down, in consequence of the cone-like
manner in which the whole posterior region converges to a blunt point. The
basal surface of the occiput is non-symmetrically flattened, the right half be-
ing pressed up towards the parietals more than the left. This flattening is
probably posthumous. In No. 955 we have another instance of this appa-
rently posthumous deformity. The highest point of the vertex in No. 957 is
at the anterior fontanelle. In No. 1040 the protuberance of the occiput over-
hangs the basal portion like a ridge. In this skull is also exhibited the basi
occipital flatness which, as we have just seen, characterizes the Minetari
skulls. No. 952 is asymmetrical, the right half being a little shorter than
the left. No. 953 belongs to the arched type. A slight flatness is observable
in the posterior, inferior part of the parietalia, but the occipital bone curves
regularly round to the foramen magnum without any flatness whatever. The
same remarks apply to No. 956. Nos. 953 and 957 are remarkably prognathic.
In No. 953 the prominence of the maxilla? gives to this skull a negrodike ap-
pearance.

A Naumkeag skull (No. 567) from Salem, Massachusetts, is a long, narrow
oval head with a projecting occiput, and a high coronal region which is dis-
tinctly carinated.

Five Natick skulls from Nantucket, upon the whole, appertain rather to a
form intermediate between the Dolicho- aud Brachycephali, than to either
one of these classes. The elevated vertex and but moderately prominent oc-
ciput give to No. 103 the arched form. No. 104 is a longer head, with a
flatter crown and a more protuberant occiput. No. 107 is an oblong, dolicho-
cephalic head. In No. 110 the upper part of the hind head is flat, and the
protuberance of the occiput lozenge- shaped.

The Natick and Narragansett skulls may be said to represent the woolly-
haired African form.

The Lenape or Delaware Indian skulls in the Academy's collection, also
fall, for the most part, into the dolichocephalic class. With the exception of
Nos. 205, 206 and 1263, they are long, though not strikingly narrow heads.
The general outline of the coronal region resembles that of the Arickarees,
Assinaboins, Cherokees and Iroquois, —occupying a place in fact between the
latter two. The occipital boss, though protuberant, is less so than in the
Arickaree, Assinaboin and Cherokee heads. The occipital region is superiorly
flattened. The upper jaws are more salient than in the heads already de-
scribed, amounting in the female skull, No. 40, as shown in Crania Americana,
plate 32, to negro-like prognathism. No. 1263 may be regarded as a Brachy-
cephalus. In consequence of the posterior, interparietal diameter being
greater than the frontal, the contour of the coronal region differs from that of
the others of this group, and resembles that shown in some of the German
skulls, especially No. 706. The posterior region is broad and perpendicularly
flattened. The coronal outline of No. 1265 resembles in some respects that of
No. 1263. Nos. 205 and 206 dug up from a street in Philadelphia, and sent
to the Academy as Delaware Indians, are very similar in form to Nos. 1263

1866.]

and 1265. They appear to be very old. The ten specimens composing this
whole group appear to belong to a form or type of skull differing in many re-
spects from those to which most of the heads already alluded to belong.
Nos. 40 and 115 are narrow ovals ; Nos. 118 and 418 maybe classed in the
same group, but they approach the arched type by being higher. They are,
indeed, transitionary in form to Nos. 1264 and 1265, which are still more
elevated in the coronal region. The form again changes in No. 1263, which is
shorter, has a triangular crown and a natter and broader occiput, and is
arranged therefore among the short heads with vertical occiputs.

The Nanticoke head (No. 1219) is a broad, low skull, with a full rounded
occiput. It resembles somewhat, No. 26, the Quinnipiack or Mohegan cranium.

The form of the Mingo skull (No. 455) is a long oval, with a broadly oval
crown and base, and a prominent occiput.

The Ottawas of Michigan may be partly referred to the arched type. No.
1007 is brachycephalic. It is a broad, low and round head. A greater pro-
minence of the occipital boss in Nos. 1006, 1008 and 1009, causes these three
skulls to depart somewhat from this type and approach the Swedish form. I
have consequently placed them in the dolichocephalic division.

The cranial specimens of the Menominees of Michigan, in the collection, differ
from each other in their general configuration not a little. No. 35, the cra-
nium of a female, resembles the Pocasset skull above referred to, — a skull
the principal characters of which are a recedent forehead, a relatively broad
posterior, interparietal diameter, and a flatly-rounded occiput. No. 563,
also a female head, resembles No. 35, but is rather less recedent in the
forehead, has a broader base, and a fuller and broader occipital region. No.
78, a male skull, is a long head, with protuberant occiput, the protuber-
ance flattened vertically, and the lower and posterior parts of the parietalia
flattened like an inclined plane. The median longitudinal line of the crown,
in consequence of the more expanded forehead, approaches an oval figure. A
fuller forehead, less prominent occiput and higher bregmatic region gives to
No. 44, (a female head,) the arched form. The contour of the coronal region
of No. 1220 is a broad, rounded oval. The posterior region is full and rounded.
In No. 1222, a Menominee chief, the crown is a longer oval, the line of the
sagittal suture more arched, and the occipital protuberance well pronounced.
No. 4."p4, figured by Morton in Crania Americana, is a short, round and asym-
metrical head, with a fuller frontal region and a less flat occiput than we find
in the others. It has a Germanic crown.

Two male Chippewa or Ojibway skulls in the collection (Nos. 683, 684,)
belong to the Dolichocephali. In the general form of the calvaria they re-
semble Swedish crania. They differ from the latter, however, in other re-
spects, particularly in the face, which, singularly enough, in its osteological
expression is very like the face of the Chinese skull. In this respect No. 684
(Chippewa) resembles No. 94 (Chinese) not a little.

Among the Miamis of Indiana we again encounter the dolichocephalic type.
No. 542, the skull of a chief, (plate 30 of Crania Americana) is in many re-
spects like the German heads in the collection, especially those from Tubin-
gen, Frankfort, Berlin, &c. It is less full in the forehead, and more promi-
nent about the middle of the sagittal suture. It has the Swedish occiput. In
the whole series, except Nos. 541, 1055, 1058 and 1233, the outline of the
crown forms a more or less rounded oval. In No. 1055, a female skull, this
outline approaches the angular Gothic form, which is still better displayed in
Nos. 1058, a young child, and 1233 also a female head, and is characterized
by a disproportionate breadth between the parietal protuberances. No. 541
is a narrow, oblong head. No. 106 approaches the arched type. In all the
specimens the forehead is quite well developed ; and in most of them the
upper part of the occiput is slightly flattened. In Nos. 1058 and 1233 the flat-
ness is nearly vertical.

In the two Illinois skulls the occipital region is wanting. No. 1010 evidently

belongs to the mesocephalic form. No. 1051* is a Mound skull. It was found
in 1848, iu a tumulus on the Blue River, Illinois. Enough of the parietals
has been preserved to show that the posterior region was flattened and that
the head should be placed among the Mesocephali.

The Ottigamies or Fox Indians, of Illinois and Wisconsin, belong to the short-
heads. Nos. 639 and 694, both male skulls, strongly resemble the angularly
round or square form. The outline of the coronal region is nearly a rounded
square. The occiput is almost vertically flat. No. 209 differs from these
two in having a, less wide sinciput. No. 415, a half-breed, is a long head with
a retreating forehead, a broad crown and the Swedish form of occiput.

The Pcttawotomies of Michigan are Dolichocephali. No. 657 (plate 34 of
Crania Americana) is a rude, massive, male skull, "remarkable," as Dr.
Morton has observed, "for its capacity behind the ears, and for the great
length and flatness of the coronal region." The apparent flatness of the crown
is in part due to the angular prominence of the parietal bones at the anterior
third of the sagittal suture. The forehead is low ; the posterior region large,
broad and angular, with no very decided or marked flatness. In No. 737, a
male skull, the crown is broader in proportion to its length than in No. 657,
and less flat ; the posterior region round and full. The parietal bones at the
anterior portion of the sagittal suture are less prominent than in No. 657. No.
1322, a young Potawatomie warrior, varies from the others in being narrower
and having a somewhat more prominent os occipitis. The face reminds me
of the Chinese physiognomy.

No. 736, the cranium of a young cbild, is brachycephalic, with a flat occiput
and bulging parietalia.

The Sac or Sauk Indians may be called long-heads. In No. 561 the crown
is oblong ; the highest point at the junction of the coronal and sagittal su-
tures. The upper part of the occiput is irregularly lozenge-shaped and pro-
minent, the basal poition rather flat. No. 1246 is a rudely carved and mas-
sive head, almost vertically flattened behind. The lower part has somewhat
the appearance of being pressed underneath towards the foramen magnum.

Two of the three skulls in the collection, marked Shawnee, are dolichoce-
phalic, the other is brachycephalic. They are of uncertain history and locality,
however, and cannot be relied upon as genuine representatives of this tribe.
No. 606 is a long, narrow, oval head, resembling the Pawnee and Arickaree
forms. No. 691, a remarkably inequilateral skull, belongs to a very different
form. The whole head is broader, and the posterior region flattened almost
entirely to the right of the median line. No. 1210, like No. 606, is a long,
narrow head ; the median, longitudinal line of the crown slightly carinated
after the fashion of the Eskimau skulls. The posterior region is broader and
more protuberant than in No. 606, while the elevation of the vertex causes
the skull to approximate the arched form.

A Shyenne skull, (No. 1041), from Fort Williams, Arkansas river, belongs
to the arched form. The superior alveolus is prominent, while the back of
the head shelves downwards and backwards like an inclined plane. This
cranium resembles the Chippeway (No. 684) and Blackfoot (No. 1227) heads.
No. 939, also a Shyenne, from the neighborhood of Fort Kearney, differs some-
what from the preceding. It is less highly arched, the occipital region is less
prominent, and the crown more triangular and broader between the parietal
protuberances.

The Iroquois skulls in the collection are Dolichocephali. They may be
classed very appropriately with the Cherokees. No. 16, exhumed near Lake
Erie, closely resembles No. 632. The occipital region is flattened superioiily.
No. 989 is probably not an Iroquois skull, though so marked. Its form differs
very much from the others. These three crania, though grouped with the
oval forms, occupy in reality an intermediate place between the oval and
arched types.

220 PROCEEDINGS OP THE ACADEMY OP

Of three Mohawk skulls exhumed near Manheim, in New York, two are long-
heads, (Nos. 895, 896), and one (No. 897) is intermediate in form between
the long and short-headed groups. They may be said to belong to the arched
form. They are shorter, broader and rounder in the base than the Cherokees,
Arickarees, Assinaboins, Minetaris, Iroquois, &c, but less round than the
Creeks, Chetimaches, &c. The posterior region is full, and the occipital pro-
tuberance though well developed, is not so prominent a feature as in some
of the long heads.

The Oneida skull (No. 33) exhibits the arched form. It is a long, narrow
head with a long, narrow face and small cheek bones.

The Seneca cranium (No. 1516) belongs to a peculiar variety of the same
general form, but is broader, and has fuller frontal and occipital regions, and
a broader base. Both it and the Oneida are long heads. Occipital region
rather flat.

The skull of Wan-yun-ta, a Cayuga Chief, (No. 417), is a very long, narrow,
oval head, somewhat kumbecephalic, with a prominent occipital protuberance.

The Huron crania belong partly to the Brachyephali, and partly to the
Mesocephali. No. 15, the head of a Huron Chief, killed near Detroit, is a
massive, strongly marked and brutish skull. The forehead is flat and re-
ceding ; the superciliary ridges very prominent ; superior maxilla everted ;
lower jaw ponderous and flared out at the angles after the manner of the typical
Eskimau skull ; malar bones projecting ; ossa nasi much incurvated ; junction
of parietal bones ridged or keel-like ; skull rather narrow ; occipital pro-
tuberance pretty well marked ; anterior bregmatic region elevated, giving an
arched outline to the whole head ; occipital flatness in the upper part of the
posterior region. In its general configuration, as viewed laterally, it resem-
bles the Creek and Chetimache skulls, but differs from them in greater eleva-
tion of crown. This coronal elevation is shown also in the other three skulls
in this group, (Nos. 607, a female, from Cleveland, Ohio, 1217 and 1218, also
female, from Detroit), which all exhibit this arched form, except No. 1217,
which is nearly round. They are all short-heads. Nos. 607 and 1218 have
the Swedish form of occiput ; the shelving, however, is not well marked, and
the occipital protuberance not very prominent. In No. 1217 the occiput
is flattened both above and below the protuberance. The whole posterior region
is here broad and flat.

Thirty-five crania from eight different tribes have been contributed to the
collection from the States of Louisiana, Mississippi, Alabama, Georgia, Florida
and the Southern part of Tennessee ; or, in other words, from that section of
the United States comprised between the Cumberland River and the Gulf of
Mexico, and the Savannah and Sabine rivers. These tribes are the Cherokees,
Muscogees or Creeks, Yamassees, Seminoles, Uches, Choctaws, Natchez and
Chetimaches.

There are six Cherokee skulls in the collection. Of these two, (Nos. 632, 634)
belonged to women, and two (Nos. 633, 635) to young girls, while two ancient
crania from the mounds in South Carolina (Nos. 1285, 1297) are males.

No. 632, found "in a cave at Springtown, Polk Co., Tennessee, north of the
river Hiwassee, and near an ancient battle-ground," is a beautifully formed
female head, setat 20 years. It is regularly and symmetrically oval. The
forehead, though low, rises evenly and gradually from the nasal suture »p
towards the coronal region, which region slopes away as gradually and is lost
in the flattened and shelving upper half of the occiput, below which appears
the regularly and smoothly protuberant occipital prominence. The head is a
long, narrow oval, and belongs to the Dolichocephali. The base is long and
narrow, the face small, and the nasal bones moderately prominent, with a
rather sharp line of junction. It is a better formed head than the Assinaboin
and Arickaree skulls. The Arickaree approaches it more nearly than the
Assinaboin. No. 633, a Cherokee girl, astat 14 years, which was found with
the preceding, has the same general characters, but is not so regularly oval

in contour. The nasal bones are natter, and the superior maxillary more
prominent. The latter bone, singularly enough, somewhat resembles that of
a Japanese skull in the collection. The rest of the head is, however, very
different. In No. 634, a woman, setat 20, the receding forehead rises much less
regularly and more abruptly towards the vertex. The posterior region as a
whole i? fuller and rounder, in consequence of the protuberance of the occipital
bone being less prominent, and the shelving and flattening of the upper part
not so great. The base is fuller posteriorly and less narrow than that of No.
632, approaching in this and some other respects the two Mound heads,
presently to be noticed. No. 633 may, in fact, be regarded as intermediate in
form and characters between these Mound heads and No. 632. In the characters
just mentioned, the two Mound heads (Nos. 12S5, 1297) exhibit some differ-
ence. The whole head is larger, has a higher internal capacity, and is very
roughly marked, the prominences and depressions being particularly well
developed. The coronal region is oblong instead of being oval, the forehead
flatter, the superciliary ridges strongly displayed, the nasal bones small and
iucurvated, the alveolar margin of the superior maxillary prominent even to
prognathism, malar bones heavy, protuberant and rough ; occipital region
flatly protuberant, the flatness not being confined to the upper part, but
ascribable to the whole occipital region, a feature mainly due to the greater
prominence of the superior and anterior portion of the ossa parietalia, the
diminished inclination of the posterior part of these bones, and the flat surface
presented by the occipital protuberance. The base behind the meati is very
broad, the mastoid processes large and heavy, and the lower jaw massive and
deep at the symphysis. Still these heads are Dolichocephali.

The crania of the Creek nation exhibit the same peculiar type to which the
Chetimache skull belongs, and of which it may be regarded as the standard.
No. 441 (Creek warrior from Alabama) is brachycephalic. No. 579, the skull
of Athlaha-Ficksa, a full-blood Creek Chief, is somewhat looger, flatter on the
top, and less round. Concerning this head, Dr. Morton thus writes : "The
broad but low forehead, and the width between the parietal bones, are highly
characteristic in this head: a front view is given of it, in order to convey an
accurate idea of the osteology of the Indian face.* Thus we see the large and
projecting cheek-bones, an arched and prominent bridge of the nose, powerfully
developed jaws and remarkably perfect teeth. The distance between the eyes
is even greater than is usual, yet the orbits themselves are not large in propor-
tion." No. 751, a Creek woman of Georgia, is a long, oval head with a pro-
tuberant occipital boss, and a superiority flattened occipital region, approxi-
mating in some respects the Kimbric skulls in the collection. In No. 1454, a
Creek Indian skull of Western Arkansas, the type again Varies. The occipital
region as a whole is greatly protuberant, yet this prominence is gradually lest
in the median line of the crown. In an equally gradual manner the forehead
and the sides blend with the coroaal region, the most elevated point of which
is in the anterior part of the sagittal suture.

The specimens in the collection constituting the Seminole group vary not a
little from each other. Some are long, and others short. No. 45G (plate 24 of
Crania Americana) is around, high, almost globular head, peaked at the junc-
tion of the coronal and sagittal sutures. No. 604 (plate 22 of Crania Ameri-
eana) is a longer head, whose full length I find, upon examination, is not fairly
shown in the first wood-cut on page 166 of Crania Americana. For the head
is more symmetrical, the flatness of the posterior region being more decided
on the left than on the right side. It is from the shortened side that the wood-
cut is taken. The increased length of the head appears to be mainly due to
the very protuberant os occipitis. The crown is les3 elevated than in the pre-
ceding skull. No. 698 is a moderately long and oval head and is more highly

and posterior views of this skull.

arcbed. A slight prominence of the sagittal suture is observed about one inch
posterior to the coronal. No. 707 is a shorter skull, and has a full, high fore-
head, a regularly arched crown, and an occiput full and rounded. No. 708
resembles 698, as do also Nos. 727, 729, 730, 732, 733, 753,- 1105 and 1286.
All these are long, oval-shaped heads, with a more or less narrow and promi-
nent occiput, and the coronal region regularly arched antero-posteriorly ex-
cept in No. 730, in which it is flatter. Nos. 726, 728 and 754 are not quite
so long ; the occipital region is also broader aud less prominent. All the above
specimens are from different parts of Florida. It, will thus be seen that in this
group there are at least two if not three distinct types: a short, high form, to
which Nos. 456 and 604 belong, and a long and more or less oval form, which
includes all the others.

The three ancient Yamassee skulls, from a mound near Tampa, in Florida,
in which they appear to have lain upwards of a century, are all long, narrow
and high skulls, belonging to what I call the arched type. They may, in fact,
be taken as the standard of this type. In Nos. 1214 and 1215 the outline of the
crown is oval ; in No. 1216 the oval outline is interrupted by the greater breadth
between the parietal tubers.

Two Cbetimache skulls, (Nos. 43, 70), one male and the other female, belong
to the brachycephalic class. They were exhumed from a cemetery in the
Parish of St. Mary, in Louisiana, and were considered by Morton as genuine
skulls of the Chetimache tribe. They are angularly round heads, with a
recedent forehead, elevated vertex, perpendicularly flattened occiput, and
striking breadth between the parietal bosses or ossific centres. The form of
these crania is, in many respects, peculiar. It belongs, as far as the general
contour goes, to the great short-headed class, in which are arranged the Ger-
mans, Finns, Laplanders, Kalmucks, Sclavonians and Turks. But from each
and all of these it differs in several respects. The outline of the coronal region
resembles a truncated spherical triangle, the base of which coincides with
the posterior biparietal diameter. In this respect these heads resemble some
of the German crania in the collection. But the latter differ from the former,
in the relation which the longitudinal diameter bear3 to the vertical. In the
general globnlarity of the posterior region, and the proximity of the foramen
magnum to the back of the head, the Chetimache cranium resembles the
Finnic, Sclavonic and Turkish types, but differs from them in the more
recedent and proportionately less broad forehead, which latter feature makes
the vertex appear more prominent. Of No. 70, the larger of the two heads
under consideration, the reader will find in Crania Americana, an excellent
lithograph, (plate 19,) together with the following observation from the pen
of Dr. Morton : — " Th^ nearly vertical occiput, the great height of the skull,
and the size and strength of the bones of the face, are not surpassed by those
of any Indian cranium I have seen," (p. 163.)

The young female Choctaw skull (No. 22) is a large, oval, high head with a
prominent occiput.

The Euchee cranium (No. 39) is a comparatively short head, with a full,
rounded occipital region. In its general form it resembles the Slavic skull.

The collection embraces 26 miscellaneous crania obtained from the mounds
in Michigan, Illinois, Wisconsin, Ohio, Tennessee and Florida.

No. 416 is an Indian skull taken from a mound seated on the high bluff
which overlooks the Mississippi river, one hundred and fifty miles above the
mouth of the Missouri. Morton describes it as " a large cranium, very full in
its vertical diameter, and broad between the parietal bones. "f It is a good
example of what I am disposed to call the arched type. It is dolichocephalic.
In its general arched form it resr /'.bles the Creek skull, No. 1454. The coronal
region closely resembles that exhibited by the Cherokee skull, (No. 634),

already described. There is a difference, however, in the basis eranii. No.
416 having a much greater intermastoid diameter.

No. 1237 is the skull of an Indian woman exhumed near Fort Chartres,
Illinois. It is bracbycephalic and closely resembles the Chetimache skull, No.
43. The two skulls undoubtedly belong to the same great type. Their calvarial
outlines are very much alike ; though No. 1237 has a somewhat fuller and less
r.ecedent forehead. They have the same shaped orhits and anterior nares,
the same small and incurvated ossa nasi, and the same prominence of the
superior alveolus. In No. 1237 the bony palate is narrower, and the super-
ciliary ridges are more strongly marked. The bases craniorum are alike.

No. 1315, the skull of an aboriginal American female, found in a saltpetre
cave at Golconda, Illinois, belongs to the arched type. It may be ranked with
the Dolichocephali. It has a decidedly prognathous, superior alveolus.

No. 1510, male Indian skull taken from an ancient mound in Illinois, belongs
to the same type as the Pocasset cranium already referred to. It is a longer
and much older head than No 1315 ■ is more rudely formed, and has the face
projecting further forward, in consequence of the prognathic upper jaw.

No. 1511, an Indian cranium found with the preceding, belongs to the same
type, but is not so long, and has a flatter and more recedent forehead, and a
broader and somewhat shorter face.

On p. 235 of Crania Americana, Dr. Morton informs us, that " in the month of
May, 1835, a cavern cemetery was discovered on the bank of the Ohio river,
opposite to Steubenville. * * * The bones contained therein appear to have
been deposited at different periods of time, those on tne top being alone in good
preservation. They were of all ages, and thrown in indiscriminately after the
removal of the flesh ; for it is well known that some tribes were accustomed
to gather, at times, all the bones of their deceased relatives, and place them in a
common receptacle. Of the great number of skulls found in this place but few
were perfect ; of which last I have received eight. These heads are thoroughly
characteristic of the race to which they pertain. They bear no evidence of
great age, and no doubt belonged to individuals of the barbarous tribes. Some
have thought them Mingoes, who were affiliated to the Iroquois; but the form
of the head does not support this surmise. * * * * All these skulls are
surprisingly alike — the vertex elevated, the occiput flat, the parietal diameter
very great, and the lower jaw massive. They are also of singularly large
capacity, and in this respect approach nearer to the Sauks and Foxes, and the
Muskogees, than to any other tribes that have come under my notice. The
mean internal capacity gives upwards of 85 cubic inches, and the facial angle
rises 78 degrees. The anterior chamber gives 38-3 cubic inches, the posterior
49-2; but notwithstanding the proportion of the former, there can be lit le
doubt that these skulls belong to the savage tribes, and not to the Toltecm
stock."

Of the above skulls, Nos. 420, 436, 437, 438, 658 and 723 resemble each other
very closely. They are all, with the exception of No. 438, asymmetrical. This
want of symmetry is due to a remarkable flattening of the occipital region, on the
left side in Nos. 436 and 437, and on the right in Nos. 420, 658 and 723. There
is, consequently, a striking want of correspondence between the antero-
posterior or longitudinal diameters of the two sides in each skull. Nos. 438
and 724 are natter in the crown, and have, therefore, a shorter vertical
diameter. All the specimens of this group may be assigned to the same
cranial type as exhibited iu the Chetimache skull, No. 43. In the Mound skulls,
however, the calvarial region is flatter, and has therefore less of the arched
form than the Chetimache crania. The occipital region iu the former is also
broader and flatter. There are facial differences likewise. Nos. 439 and 210
are longer, narrower, more oval and without the occipital flatness. They pre-
sent nothing of the arched form. In No. 723 the narrowness of the os frontis,
the wall-like flatness of the occipital region, and the lowness of the crown
combine to produce a singularly triangular form.

224 PROCEEDINGS OF THE ACADEMY OF

No. 53, from a mound at Circleville, Ohio, is a long-head. In general form
it is like the Blackfoot cranium No. 1227, but has a more prominent occiput.

No. 1287, from a mound at Chilicothe, Ohio, very closely resembles the
Pocasset skull, from which, it differs by being somewhat broader. It occupies
a position intermediate between the long and short heads. No. 1288, found
in the same mound, is a long boat-shaped head with a very protuberant occipital
boss.

No. 1512, from a mound in the Scioto Valley, Ohio, is a brachycephalic skull.
Of this cranium Dr. Morton thus wrote : " This is, perhaps, the most admirably-
formed head of the American race hitherto discovered. It possesses the
national characteristics in perfection, as seen in the elevated vertex, flattened
occiput, great interparietal diameter, ponderous bony structure, salient nose,
large jaws and broad face. It is the perfect type of Indian conformation, to
which the skulls of all the tribes from Cape Horn to Canada more or less ap-
proximate. Similar forms are common in the Peruvian tomb3, and have the
occiput, as in this instance, so flattened and vertical as to give the idea of
artificial compression ; yet this is only an exaggeration of the natural form,
caused by the pressure of the cradleboard in common use among the American
nations."

No. 992, from a mound in Tennessee, resembles No. 1512. It is asymmetrically
flattened. It is a short head, with a flat wall-like occiput and a triangular crown.
The forehead and whole crown, indeed, are narrower than in Xo. 1512. It is just
such a form as we might suppose the Pocasset type would take if pressed
behind.

No. 1271, from a mound near Huron river, Ohio, is a short head with an al-
most vertically flat occiput. No. 1272, found with the preceding, is a longer and
more oval head, with a more rounded occipital region.

No. 1270, from Detroit, is a long, narrow, oval head, resembling, in general
form, the Arikaree skulls.

No. 1455, from a mound in Florida, is artificially flattened in such a manner
as to resemble somewhat the Chinook or Charib skulls.

No. 212, the cast of a Kenhawha skull, is a short head with a vertical
occiput.

No. 1557, from the banks of the Susquehanna river, is a long, oval head
with prominent parietal and occipital protuberances.

No. 215, from South Carolina, is brachycephalic. It belongs to the globular,
Mongolia form. No. 216 is a long head, as are also Nos. 218 and 219.

No. 134 is a long, narrow, oval and high head, with a prominent occiput.
Nos. 136 and 146, from Warren county, Pennsylvania, are both dolichocephalic.

No. 135, found on the brow of a bill about two miles below Trenton, New
Jersey, is a long, asymmetrical head. It is probably the skull of a Delaware
Indian. The supraorbital ridges are more prominent, however, than in the
specimens of the Delaware group. This feature is also exhibited in the frag-
ment, No 249, found in the same locality.

The collection contains four Californian skulls. No. 1514 is the cranium of
a California Indian, from a mound near Sacramento City. It is a dolicho-
cephalic bead ; long and flat; the forehead narrow and low. The calvaria
widens out posteriorly to the parietal tubers; the most elevated part of the
vertex is on a line coinciding with the greatest interparietal diameter. The
posterior part of the parietal bones shelves down to the prominent upper
part of the os occipitis. The base is long and oval. The face of this skull is
wanting.

No. 1565 is a fragmentary Indian skull, thickly encrusted with carbonate of
lime. It was found in a cave in Vallecita, Calaveras Co., California, along
with 300 other human crania, all embedded in limestone. It has the same
general appearance and conformation as the preceding skull. The occiput is,
however, more prominent, and the contour of the more angular crown ap-
proaches a lozenge-shaped oval. The calcareous incrustation extends, in some
places, to the depth of an eighth of an inch.

NATURAL SCIENCES OP PHILADELPHIA. 225

In the south-western part of the North American continent lies an extensive
tract of country designated by Prichard, Latham and other systematic
ethnologists as the Paduca area. This ethnological region extends, according
to Latham, from the Pacific ocean, in a south-eastwardly direction, to the
Gulf of Mexico; from the water-system of the river Columbia to that of
the Sabine river, and from north of 45° N. L., to south of 25° S. L. It is
occupied by numerous, imperfectly known and unclassified tribes to whom the
term Paduca has been applied provisionally. The tribes of this group repre-
sented in the collection are the Shoshonis or Diggers, Utahs, Moquis, Apaches,
Navajos, Lipans, Camanches, and that race of people which, though seem-
ingly now extinct, once formed the numerous population of the large towns,
long since in ruins, such as Quivira, Abo, Guarra, Pecos. &c.

The Shoshoni, or Root-Digger skulls, three in number, vary in form. No. 1446,
obtained on the Trucky river, in the California mountains, belongs to a peculiar
form or type of which examples have already been pointed out in thePocasset,
Narragansett and other tribes. It is, however, a broader skull. The crown ap-
proaches the triangular form ; the forehead is rather broad and flat. The whole
crown rises up to a sort of eminence situated between the parietal bosses. The
occipital region is broad and rather flat, the basis cranii broad and rounded. Nos.
1447 and 1449 are long heads. They differ in the form of the crown, which in
No. 1449 is a long, regular oval, but in No. 1447 is flat and broad posteriorly
between the parietal tubers. No. 1449 resembles somewhat the Arickaree form
in both the occipital region and the basis cranii. No. 1447, in consequence of a
greater projection of the occiput, exhibits the supero-occipital flatness of the
Swedish form.

Of this group Dr. Morton thus wrote: "Two of these skulls are so small,
so receding in the forehead, and so depressed over the whole coronal region,
that they could not, by intrinsic evidence alone, #have been identified with any
branch of the aboriginal American race. They want the vertical occiput and
general rounded form of the Indiau head, and have a narrowness of the face
unusual wiih these people."*

No. 1448, from the Eastern slope of the Sierra Nevada, and recorded in the
catalogue as pertaining to none of the Shosboni tribes, is a large, massive,
heavy head, rudely developed. In the median line the crown runs back to an
elevation similar to that seen in the Potawatomie skull (No. 657) figured by
Morton; from this prominence descends a broad and almost perpendicularly
flat occipital region. Hence, when viewed in profile, the skull has a quad-
rangular appearance. This ponderous head, which Dr. Morton termed " the
very type of Indian conformation," differs decidedly from Nos. 1447 and 1449,
and resembles No. 1446.

In November, 1855, Dr. Thomas J. Turner, while at Mare Island, California,
dug up two skulls which he supposed to be those of Digger Indians. They
were buried under a mass of calcined shells, some seven feet below the sur-
face. One of these crania, No. 1027, is that of a female in all probability,
and is the facsimile of the Shoshoni skull No. 1449. It is a long, narrow head
with an oval occiput. The other skull, No. 943, is a long, high head, differ-
ing considerably from No. 1027 and all the specimens grouped in the catalogue
as Shoshonees. Nos. 1446 and 1448 should evidently be classed together as
belonging to one tribe, while Nos. 1447, 1449 and 1027 clearly belong to an-
other group.

The skull of a young Utah girl (No. 140) is dolichocephalic, with prominent
occipital and parietal protuberances, and a rhomboidal crown.

Two Moqui crania, Nos. 138 and 139, are small, non-symmetrical heads.
Both have the posterior region flattened ; the one slightly, the other decidedly.
No. 138 exhibits the shelving, parieto-occipital flatness; the other, No. 139,
has the back of the head almost vertically flattened. No. 139 is brachycepbalic;

* Proceed. Acad. Nat. Sci., vol. iv. p. 75.

the other may be said to be mesocephalic. In No. 138 the occipital protuber-
ance is well marked , in No. 139 this protuberance is nearly obliterated.

Three crania from Quivira and Quarra, New Mexico, (Nos. 1032, 1033 and
1034), are brachycephalic. The occiput in all is more or less flattened, but
most decidedly in No. 1032.

A Pueblo craDium (No. 930) is dolichocephalic with shelving occipital flat-
ness. Another Pueblo skull (No. 937) is short, high, and non-symmetrical.

A skull from Santa Fe (No. 931) is a short, asymmetrical and occipitally
flattened head.

No. 1346, the skull probably of an ancient tribe of Lipan Indians, from the
celebrated, sepulchral cavern of Bolson de Massimi, between San Sebastian
and San Lorezo, in the State of Durango, New Mexico, is a long, oval head,
with a very prominent occiput. No. 1345, the cranium of a modern Lipan, is
shorter and has a somewhat more rounded occiput.

The skull of a very young Apache child (No. 141) is dolichocephalic, and in
its general form very much like the Utah cranium, No. 140. No. 145, the skull
of a Mescalero Apache Indian, from the Desert of Black Hills, Texas, recently
added to the collection, is a long oval and very symmetrically formed head, with
protuberant occipital and parietal protuberances. It also resembles No. 140.
No. 1035, the skull of a Mescalero Chief, is an oblong, barrel-shaped head with
a rounded occiput and broad base. No. 935, a Mogoyon Apache, is a long,
high head, very broad between the mastoid processes. No. 936, the cranium
of a Navajo Indian, is a long, ponderous, broadly oval head with a broad base,
a broad, high and almost vertical forehead, and a flattened posterior region.
In its general form it resembles somewhat Nos. 1446 and 1448 of the Shoshoni
group.

No. 247 is the skull of a Camanche Indian, supposed to be that of " Yellow
Wolf," head chief of his nation. It was found in a very conspicuous tomb, in
a large Indian burial ground, on the head-waters of the Colorado River, near
the deserted Fort Phantom Hill, Texas. It is a dolichocephalic cranium, of the
arched type.

No. 34, a Mexican Indian from Acapancingo, eighteen leagues south of
Mexico, and referred by Morton to the Tlahuica tribe, is a dolichocephalic,
prognathic female skull.

No. 734, a male skull exhumed near the Indian village of Guahapan, on the
mountain Popocatapetl, is mesocephalic and broadly oval. No. 735, a female
skull found with the preceding, is a long head of the arched type. These two
crania were regarded by Dr. Morton as probable examples of the ancient Aztec
nation.

Three skulls from an ancient cemetery at Otumba differ in form; Nos. 714,
a male, and 716, a female, are dolichocephalic. The first, however, forms a
broad oval, while the second belongs to the arched type. No. 715 is brachy-
cephalic and globular.

Nos. 717, 718 and 720 are ancient Mexican crania from Tacuba. The first
belongs to the arched, the second to the cubical, and the third to the broadly
oval type. The first two have pyramidal faces. No. 718 is brachycephalic and
carinated also. Nos. 717 and 720 are dolichocephalic.

The Otomie skulls are, for the most part, dolichocephalic. No. 1323, the
cranium of Vicente Rivaz, an Ottomie Cazique of the pure Mexican race, is a.
narrow oval in form. No. 1001 is arched. No. 1002 is phoxocephalic, with a
very protuberant occiput.

No. J 004, the skull of an ancient Mexican of the Tlascalan nation, is bra-
chycephalic and globular.

No. 1005, a woman of the Chechemecan nation is mesocephalic and arched.

No. 681, a Mexican woman of the Pames tribe, is intermediate between the
long and short heads, and is phoxocephalic. Another female skull of the same
tribe, No. 1313, is a broadly oval dolichocephalus.

No. 1314, exhumed from an ancient cemetery at Cerro de Quesilas, near the

[May,

NATURAL SCIENCES OP PHILADELPHIA. 227

city of Mexico, and regarded by Dr. Morton as a relic of the genuine Toltecan
stock, is a mesocephalic, male skull, with a broad and flat vertex. It resem-
bles somewhat the Maya cranium referred to below.

Nos. 682, 234, 1353 and 1566 are brachycephalic and cubical. No. 1515, a
modern Mexican Indian cranium, is intermediate in length and phoxocephulic.

Nos. 1347, 555, 557, 558 and 689 are dolichocephalic and broadly oval. No.
556 is also dolichocephalic, but belongs to the arched type. It has a mam-
millated occipital protuberance.

The skull of a Maya Indian of Yucatan, No. 990, is dolichocephalic, and
broadly oval, with a very flat crown and prognathic jaws.

The Araucanian female crania, Nos. 651 and 652, are long, broadly oval
heads. The sides and occipital region being slightly flattened and not. rounded,
give a certain angularity or squareness to these he ids,— a feature which is
more marked in another female skull of this group, No. 654, ou account of the
very flat vertex. No. 655, a male cranium, is a longer oval, with a somewhat
more prominent occipital region. No. 656, a female skull, resembles some-
what the form exhibited by the Pocasset head. No. 995, also a female, has a
higher vertex, and is more protuberant in the upper half of the occipital
bone. No. 997, a male skull, exhibits the arched type. Nos. 221 and 222 are
arched like the Yamassee skulls.

The only unflattened Charib skull in the collection, No. 692, is a long,
moderately high and broadly oval skull. No. 638 and a cast, No. 225, though
compressed or flattened heads, evidently belong to the Dolichocephali.

The Brazilian crania are all dolichocephalic. The Tapuyo skull, No. 1254, is
a large, long and broadly oval cranium. Three other Brazilians, Nos. 1513,
1528 and 1529 are long, oval heads more or less prominent behind. The
Guaycuru skull No. 1530 is also long and oval in form, with a prominent
occiput. Nos. 1555 and 1556, two Gentoo skulls from the Purus River, a tribu-
tary of the Amazon, are small, oval dolichocephalic crania.

The collection contains a cast of the skull of a Patagonian, and
another of the head of a Puelche girl. The former, No. 1357, (of which No.
226 is a duplicate), is large, long and cylindrical or barrel-shaped in form.
The latter, No. 1359, is a high, short and broad head with a flat, occipital
region.

Of the 245 Peruvian crania belonging to the Academy's collection, 50 are
dolichocephalic and 168 brachycephalic; while the remaining 27 fall into the
mesocephalic or intermediate class rather than into either of these two ex-
tremes. To the elongated or dolichocephalic form belong all the specimens
from Arica enumerated on pages 76, 77 and 78 of my Catalogue of Human Crania,
together with nine others from the same locality, added to the collection since
the publication of the catalogue. These skulls are artificially distorted, and
are referrible to one or another of the grotesque forms exhibited in plates 2, 3,
4 and 5 of the Crania Americana. The Arica skull, No. 932, is brachycephalic.
To the long-headed class belong also the following, viz: Nos. 415, 1048, 1417"
and 1445, from Pisco; No. 231, from Lima; No. 11, an ancient Chimuyan, from
Truxillo ; No. 637, a Quichua of upper Peru; No. 1517, a child from Payta ;
No. 232, from Atacames ; the casts (Nos. 700, 701, 702, 703, 704, 705, 710 'and
711) of ancient Peruvian crania from Titicaca, Coracolla, Pomete and Chim-
gauge; and Nos. 940, 941 and 942 from the ruins of old Callao. In Nos. 1048,
1417 and 231, we again meet with examples of the narrow, oval form or type ;
in Nos. 1445, 1 1, 232, 940 and 942, of the broad oval ; and in Nos. 637, 1517 and
941, of the upsicephalic or arched form.

Ninety-three skulls from Pachacamac are Brachycephali ; eleven others,
Nos. 402, 409, 571, 631, 696, 1453, 1457, 1462, 1467, 1489 and 1499, are meso-
cephalic. Of these latter, Nos. 571, 631, 696, and 1499, may be referred to the
arched form. Had the process of growth and development not been inter-
fered with in No. 76 by artificial means, this skull would have been a broadly
oval Dolichocephalus. In the brachycephalic group must also be arranged all

the crania from Pisco, except three — Nos. 445, 1048 and 1445 — which are
dolichocephali ; and four — Nos. 1061, 1326, 1369 and 1423 — which are meso-
cephali and all referrible to the arched form. Another series of Peruvian crania,
collected. at Paracas Bay by Dr. Turner, (Nos. 1298, 1273,1274, 1275, 1303,
1304, 1305, 1025 and 1026, none of which are recorded in my printed Cata-
logue), belong likewise to the Mesocephali and to the phoxocephalic group of
the arched form or type. All the skulls from Santa are brachycephalic, as are
also all from Lima, except No. 231, which is a long-head, and No. 68, which is
a broadly oval mesocephalus. No. 451 is alsomesocephalic and arched. Nos.
1518, from Payta, 1046 from Guamay, 447, 448 and 233 from Callao are
brachycephalic.

From the above statements it will be seen that among the Peruvian crania in
the Academy's collection the Brachycephali are greatly in numerical excess
over the long and middling long-heads. As regards their type or ethnic form
they may all be placed in the kubicephalic or square-headed group.

As a summary of the more prominent facts recorded in the preceding pages,
and in order to exhibit as distinctly as possible the leading differential charac-
ters of the American Indian crania contained in the museum of the Academy,
I have constructed the following tables, and attempted therein to classify these
crania according to their length as compared with their heighth and breadth,
and according to their general ethnic forms or types. Grouping them in this
manner is essentially preliminary to comparing them with corref ponding groups
of skulls of the old world. Such a comparison I purpose to institute in a future
monograph to be devoted to the consideration of the large collection of
Esquimau skulls referred to above.

In the first fable the American races represented in the collection are
grouped in accordance, for the most part, with the philological arrangement
or classification of Latham, while their crania are arranged in dolichocephalic
mesocephalic and brachycephalic classes. In the second table these skulls are
classified with especial reference to the more prominent of the ethnic or typical
forms exhibited by the entire series. This classification must not be regarded,
however, as rigidly accurate. It is provisional only, as all such classifications
must necessarily be, and subject, therefore, to future revision. Large a3 is the
collection of American skulls now under consideration, it is, nevertheless, ex-
ceedingly defective. With the exception of the Peruvians and, next to these, the
Seminoles and Esquimaux, the specimens representing the different tribes are
but few in number, and of the identity of some of these I am not yet perfectly satis-
fied ; moreover there are many well-known tribes and races of which the collec-
tion contains not a single cranial specimen. Though the collection is not
sufficiently diversified to exhibit all the probable cranial forms of the aborigi-
nal Americans, it is ample enough to show that among these people there are
long, short and intermediate heads divisible into pyramidal, oval, cylindrical,
arched, wedge-shaped, flat, globular, cubical, prognathic and other forms, all
as different from each other as are the distinct types of the old world. In as-
signing the skulls to these typical groups or classes I have experienced the
usual difficulty in locating the transitionary or aberrant forms, which are
always, in large collections, more or less numerous, and which often effectually
obliterate all sharply-draw lines of demarcation. Future examinations and
comparison may cause these transitionary specimens to be transferred from,
groups in which I have at present placed them to others ; but this transposition
though it may ultimately lead to the establishment of other types, can in no case
diminish the stability of those which I have just indicated. These groups, by
means of the intermediate forms, graduate into or blend with each other, and
we are thus admonished here, as in other departments of natural history, of
nature's eternal enigma of a certain undefinable, serial unity pervading and
co ordinating an endless diversity of forms.

Table II. Classification of Aboriginal American Crania according to their Ethnic

Forms.

A. Pyramidal or Pyramidocephalic* Form.

General Characters: Dolichocephalic; calvaria carinated and pyramidal;
face lozenge-shaped and broadest below the orbits.

Esquimaux, Nos. 1558, 1559, 1560, 1561, 1562, 1563, 674, 675, 676, 677, 678,

B. Oval or Ooidocephalic| Form.

General Characters. Chiefly dolichocephalic ; vertex and base of the skull
more or less oval in outline. This oval generally regular, sometimes rhom-
boidal or angular ; sometimes loDg and narrow, sometimes rather short and
broad. Occipital region more or less full and prominent ; occasionally very
much elongated. Occipital protuberance sometimes knob-like, sometimes
acuminated. Posterior portion of the ossa parietalia shelving downwards and
backwards like an inclined plane ; a portion of this plane sometimes formed by
the upper half of the occipital bone. Forehead moderately well developed in
breadth and beighth.

Subdivisions. 1. Cymbecephalic or boat-shaped form, in which the occiput is
exceedingly protuberant. 2. Narrow oval form. 3. Broad oval form. 4.
Barrel-shaped or cylindrical form. 5. Angularly oblong form. 6. Artificially
elongated form.

From the foregoing statements and from a careful examination of the pre-
ceding tables we may conclude :

1st. That the crania of the Aboriginal Americans are divisible into Dolicho-
cephalic, Mesocephalic and Brachycephalic groups.

2d. That the Dolichocephali greatly preponderate in numbers over the Meso-
cephali and Bracbycephali.

3d. That in the case of the Peruvian skulls in the Academy's collection,
however, the short, square heads are more numerous than the elongated forms.
4th. That in North America neither the Dolichocephalic nor Brachycephalic
tribe9, when first known to Europeans, were restricted in their geographical
distribution to any particular locality. While the former were scattered over
the continent, through all degrees of latitude and longitude; the latter appear
to have been, if we may judge from the specimens in the Museum, more numer-
ous about the Great Lakes, at various places in the interior, in the south near
the Gulf of Mexico, in the so-called Paduca area, and especially along the
north-west coast. In general terms we may say that on the eastern or A an-
tic side of the continent the Dolichocephali appear to have prevailed ; and on the
western or Pacific side the Brachycephali. This in a great measure seems
to have been, and still is the case in South America.

5th. That long and short-headed tribes or races are very commonly found
throughout the two Americas side by side. In the extreme north, for example,
dolichocephalic and brachycephalic forms are contrasted in the Esquimaux
and their geographical neighbors, the Konaegi or Kadiakan Aleutians; and
again in the far south these diverse forms are exhibited in the Patagoni-ins
and Puelches.

6th. That this contrast in cranial forms existed among the extinct races of
America, as it now does among extant tribes.

7th. That in comparing the old and new worlds by their cranial forms, we
find that while in Europe and Asia the hrachycephalic is the prevalent form,
in North America the dolichocephalic is the predominant type.

8th. That while in Africa all the people are dolichocephalic, in South Ame-
rica they are nearly equally divided between the long and short forms.

9th. That while in Europe and Asia the Polar or Arctic people are chiefly
brachycephalic, in America they are wholly dolichocephalic.

10th. That various European, Asiatic and African crania, such as those of
Norwegians, Swedes, Anglo-Saxons, the Germanic or long-headed G rmans,
the Gothic or short- headed Germans, the Finns, Lapps, Turks, Sclavonians, Kal-
mucks, Burats, Prognathic Negroes, &c, find representatives among the native
cranial forms of America.

11th. That this homoiocephalic representation is not confined to normal
skull-forms, but is shown in abnormal or artificially distorted skulls also.

12th. That the Dolichocephali are divisible into at least six well-marked
forms or types, viz. : the pyramidal, boat-shaped, oval, cylindrical oblong and
arched.

13th. That the Brachycephali maybe divided into round or globular, and
square or cuboidal classes.

14th. That the Mesocephali also consist of two sub-groups, one of which is
transitionary to the square or cubical, and the other to the round or globular
Brachycephali. ,

15th Tnat these ethnical or typical "groups are founded upon osteological
differences as great, and apparently as constant, as those which, in Europe,
suffice to separate the Germanic and Celtic stocks on the one hand, from the
TJgrian, Turkish and Sclavonian, on the other.

236 PROCEEDINGS OF THE ACADExMY OP

On the Introduction of the American SHAD into the Alabama Eiver.

BY W. C. DANIELL, M. D., OF SAVANNAH, GEO.

(Communicated through the Smithsonian Institution.)

My success in establishing the White Shad in the Alabama River being now
complete, I propose to give jou a detailed statement of the matter.

Having long doubted the generally received theory of the annual migration
south from the uorthern seas, of the White Shad, and of the consequent annual
migration thither of the young fry hatched from the eggs deposited by their
parents in our fresh water streams, I made inquiry of our fishermen, and learned
that minute but distinctive differences were readily detected between the
White Shad taken in the Savannah River and those taken in the Ogeechee
River, eighteen miles south of the Savannah River. Fully satisfied of this fact,
I readily concluded that the young shad that descend to the sea never go so
far from the mouth of the river descended, as to lose their connection with it,
and that they ascend iu the spring the same river which they had descended as
young fish the previous summer. Then the feeding ground, so to speak, of the
shad is iu or near the mouth of the river. If the. young shad does attain its
growth at the mouth of the Savannah and of the Ogeechee Rivers, may there
not be equally good feeding-grounds at the mouihs of the Alabama and other
rivers flowing into the Gulf of Mexico? To solve this question, I, wiih the aid
of my friend Mark A. Cooper, Esq , whose residence on the Etowah River in
Barton County supplied an eligible locality for the experiment, in the early
summer of 1848 had placed in a small tributary of the Etowah River the fe-
cundated eggs of the White Shad, which I had myself carefully prepared at
my plantation on the Savannah River, ten miles above this city, from living
parents. These eggs, so deposited by Major Cooper, were daily visited by him
until they had all hatched. I sent another supply of fecundated eggs to Dan'l.
Pratt, Esq., at Prattsville, near Montgomery, Ala., in 1853 or '54, as he writes
me, which he deposited in a small creek. Inasmuch as he left home soon after,
and was absent " some weeks," he can only report that during that absence
heavy rains raised the waters in the creek, and washed away the " pen " in
which he had placed the White Shad eggs supplied by me. Nothing can
therefore be safely affirmed of the success of this second deposit, nor is it im-
portant, as in 1851 or '52 the White Shad had already been taken in the fish-
traps at the foot of the Falls of the Alabama, at Wiiumka, and of the Black
Warrior, near Tuscaloosa, though unknown to me at the time of supplying
Mr. Pratt with the fecundated eggs.

Through the kindness of a friend at Montgomery, Ala., a shad taken from
the Alabama River was sect to Prof. Holbrook, of Charleston, S. C, and he
wrote me that he " felt certain " that the fish received and examined by bim
was identical with the White Shad of our Atlantic rivers. I have a letter from
Chas. T. Pollard, Esq., of Montgomery, Ala., of 6th inst., in which, speaking of
the White Shad in the Alabama River, he says: "They have gradually in-
creased in quantity since they first appeared, and have year by year increased
in size, until, to use the words of a native of South Carolina, who lived many
years near Sistera Ferry, on the Savannah River, — they are now equal to the
best Savannah River Shad."

The White Shad have chiefly been taken in the fish-traps at the foot of the
Falls atWetumpka and near Tuscaloosa. One, I am informed, has been taken
from a trap at the head of the Coosa River, near Rome, in tbis State, and only
some sixty miles below the locality in which the eggs were deposited by Major
Cooper, in a tributary of the Etowah River. I also learn that some few have
been taken with a dip net, near Selma.

I think that we may safely conclude that the White Shad may be as success-
fully established in the Mississippi River as it has been in the Alabama. Since

[May,

NATURAL SCIENCES OF PHILADELPHIA. 237

feeding-grounds for that delicious fish exist at the mouth of one river flowing
into the Gulf of Mexico, may they not exist at the mouths of other or all the
rivers discharging into that sea ? Time must answer that question.

When the presence of the White Shad in the Alabama River became known,
some enterprising citizens of Montgomery came to Savannah and procured a
number of the young shad from the river, placed them in a hogshead of water,
which was kept cool by occasional supplies of ice, and took them by railroad
to Montgomery and placed them in the Alabama River. The purpose of this
measure was to multiply more rapidly the shad already established in that
river. My agency in placing the White Shad there was not then, I believe,
known to those gentlemen, one of whom was Colonel Pickett, the Historian of
Alabama.

June bth.
Mr. Cassin, Vice-President, in the Chair.
Twenty-two members present.

The following paper was offered for publication : " Description of new
species of Diurnal Lopidoptera." By Tryon Reakirt.

Dr. Leidy observed that the small collection of fossils presented this evening
by Dr. A. C. Hamlin is of interest, from the fact of one of them being a bird
bone. Two accompanying shells are Balanus Hameri and Sasicava rugosa,
post-tertiary species. The specimen^ were obtained from a railroa"d cutting on
the banks of the Penobscot River, Bangor, Maine, 47 feet below the surface.
The bird bone is a right humerus, resembling in its construction that of a
Curlew.

, Except the so-called bird tracks of the triassic sandstones, almost no fossil
remains of birds have been found in the United States. The Museum of the
Academy contains a few specimens, which have not been identified, as
follows :

A left humerus, almost identical with the one above mentioned, both in form
and size, from Tarboro', Edgecombe Co., N. C, presented by Dr. Booth.

The lower extremity of a left humerus and a right radius, from a miocene
formation of Maryland, presented by T. A. Conrad. The specimens resemble
in construction the corresponding parts in a Snipe, but are as large as in the
Curlew.

The lower end of a left tibia, from Burlington Co., N. J., described by Dr. Har-
lan as the remains of a Snipe, Scolopax (Med. and Phys. Res. p. 280.)

The lower end of a left tibia, from the Niobrara River, of Nebraska, discov-
ered by Dr. Playden, in association with a multitude of mammalian remains.
It resembles the corresponding part in a Crane. It is the only ornithic fossil
among all the vertebrate remains from Nebraska, amounting to several tons in
weight, which Dr. L. had detected.

the sulphureous basal portion remaining the same; there is, however, an ob-
long black discal spot upon the primaries, and the black terminal line of Hila-
ria is either entirely wanting, or represented only by a few faint atom's ; the
nervular extremities of the secondaries are marked by minute dark points.

Under side greenish white, crossed with innumerable waved darker lines
upon the upper half of the primaries and their apex, and over the secondaries.
Costa of primaries continuous reddish brown for a short distance from the
base, followed by scattered points thence to the apex, and along the outer
margin, all of the same color ; also an indistinct line running in from the
apex : a large rounded ferruginous discal ocellus, pupilled with violaceous-
silvery ; base suffused with yellow ; an orange streak within the cell.

Secondaries darker than the primaries, lightened with pale greenish white
above the subcostal and median veins; a small silvery spot, encircled with
ferruginous, on the lower disco-cellular, and six minute rosy, or rose-brown
spots, one in each interspace, midway between the cell and outer margin.

Fringe greenish white ; expanse three inches.

Thorax black, covered with long greenish-yellow hairs ; abdomen and lower
•portions greenish-white; antennae rosy or ferruginous, darker on the club.

Female, base of both wings pale yellowish-white; the mesial portions be-
come more yellowish, and the depth of color is gradually increased to yellow-
ish-orange on the outer margins; a large rounded black discal spot on the
primaries ; a bright ferruginous border at the apex, and on the outer margin,
extending below half its length, at first continuous, afterwards maculate; in-
terior to this, a maculate series, similarly colored, bent nearly at a right angle,
just below the apex, and terminating at the costa on the one side, and on the
other just above the end of the marginal border.

Below, bright ochreous-yellow ; the markings of the male remain constant,
with the difference in color, with the reappearance of the interior bent band of
the fore wings, and the addition of a rounded, ferruginous spot within the cell
of the secondaries, obliquely above the discal ocellus; the six submarginal
spots of the same wing are considerably enlarged.

Fringe yellowish orange; expanse 2-65 inches.

rectangular ; outer margin from the middle curved outwards, and deeply
crenulated ; a large apical black patch extending from the outer third of the
costa, nearly to the inner angle ; its anterior outline presents two short termi-
nal, nearly straight lines, and three prominent curves, of which the upper is
double the langth of either the others, but shallow, while the lower two ap-
proximate to a semicircle in form, and are of considerable depth.

Hind wing with the outer margin between first and second median wein-
lets produced into a longish pointed lobe, nearest the second branch, and
partially entered by it ; the ends of the nervules marked by minute dark points,
otherwise the secondaries are immaculate.

Underneath, the apex of the primaries and the secondaries are suffused with
ochreous, and reticulated with fine ferruginous lines ; white atoms are sprinkled
over the surface, and in some places, form condensed spots; three of these are
situated below the cell and first veinlet, another at the upper end of the first

7. EOPLffiA PAPUANA, nOV. Sp.

Male. — Upper surface dark velvety brownish-black, paler on the outer mar-
gin of the fore, and upon the hind wings ; two long, rather narrow dull brown
vittae in the medio-posteiior interspace ; a submarginal row of seven chalk-
white spots, fringed with bluish ; of these the first two are respectively above
and below the filth subcostal veinlet, both being larger than any of the follow-
ing) — the second mostly so, — and in each of the ensuing interspaces there is
one, the fourth being the least, and the seventh tripartite, composed of two
small lunes and a dot ; there are three minute dots nearer the margin, ob-
liquely below the fourth, fifth and sixth spots respectfully.

Secondaries with a submarginal row of ten spots, of which seven are oval ;
the main axis of the first three is placed transversely to that of the others ; the
eighth and ninth are rounded, and the tenth a narrow streak ; following these
is a marginal series of small dots, obsolescent towards the outer angle.

Under surface, the submarginal row of above is reproduced, having added a
small spot nearer the costa. There is also a marginal series of eleven .small
rounded spots; a small bluish spot above the upper radial, near the cell,
another within the cell, and a third, considerably larger, in the medio-superior
interspace ; a small oblong patch of appressed hairs in the medio- central
interspace.

Secondaries have two white spots at the base of the wings ; the submarginal
series of above, and a marginal row of twelve, the last coalescing with the ter-

I am not quite sure of the specific distinctness of this beautiful Danaid;
many of the published descriptions of the members of this genus are extremely
imperfect, and the insects themselves so subject to variation that it is very
difficult to determine them correctly, without comparison with the original
specimens.

"The males have a patch of peculiarly formed, and closely placed scales,
situated on the sub-median nervule of the posterior wings, not far from tbe-
ou'er angle.

" The males of the first group have the anterior tibiae and tarsi covered with
closely appressed scales." — E. Doubleday,

There exists no sufficient reason why Hubner's genus should not be recog-
nized as valid, and the few species composing it be separated from the great
mass of the Danaides.

Geographically, structurally, and in coloration, they differ as much from
their former congeners, as is possible within the range of a closely connected
family ; and it seems to me, that only from a total misapprehension of the rules
of genetic formation, could such a naturally well defined group have been
merged into another of opposed forms.

The four species of which it has been hitherto composed are all essentially
African, as will be seen from the following summary :

1. Amauris phaedon, Fab. Mauritius.

2. " echeria, Stoll. S Africa.

3. " egialea, Cram. W. Africa.

4. " niavius, Linne". W. Africa.

To these well known species I now add a fifth, to which Dr. Boisduval has
given the MS. name of Danais ochlea ; its description follows.

8. Amauris ochlea, Boisd. sp.

Danais ochlea, Boisd. MSS.

Male. — Upper surface : primaries rich velvety black ; a transverse sub apical
white band, cut in three parts by black veinlets ; another much larger trans-
verse band occupies the lower central portion of the wing, exieuding from the
subcostal to the submedian vein, and is divided by the black median nervule
and first branch into three large white patches ; a srnall rounded spot near the
-apex ; two others on the costa, between th? transverse band, above the upper of
which there is also a miuute narrow dash, and three more near the outer
margin, placed bttween the lower pot lion of the first band and the inner angle :
of these the first is the largest ; between the first two of these spots and the
margin there are three very minute dots. All of these markings white, or pale
glaucous white.

Secondaries dark brownish-black; a large semi-transparent white space
occupies the basal and mesial areas, extending from the costal nervure to the
abdominal margin, divided into ten spots by the black veins and veinlets ;
three submarginal white spots on the upper half of the outer margin.

Fringe black, alternated with white on the hind wings ; the primaries are
cut with white only near the middle of the outer margin ; expanse three inches.

Underneath chit- fly as above ; the apex of the primaries and the terminal
border of the secondaries become brownish. Upon the first there is an addi-
tional small apical spot, and in place of three marginal spots there is a row of
seven, the two lower coalescing with the third subinarginal spot. The second-
aries have a white spot at their base, and two submarginal rows, composed
respectively of eleven and thirteen white spots.

tween which and the discal one is tinged with yellowish ; the base is also
marked with a yellow spot; expanse 3-25 inches.

Guatemala, I am indebted to Mr. H. W. Bates.

10. Melinjea paraiya, nov. sp.

Male. Upper surface; apical half of fore wings dark brownish-black, with a
very irregular interior outline, closely resembling that of M. Egina&B far as the
first median veinlet, thence it is curved inwardly, and terminates in an attenua-
ted line on the basal third of the hind margin ; across this there are two equi-
distant, semi-opaque yellow bands, of which the apical is continuous, and the
other is divided into three spots, the central one being much the least: there
is also a sub-marginal row of smajl whits spots, varying from six to ten in
number; the basal third of the surface, excepting the costa, throughout its
entire length, which is black, is rich orange tawny, and the space between this
and the outer black portion is occupied by a broad semi-opaque yellow belt ;
within the cell there are two large rounded black spots, which mark the
chromatic line of separation.

Secondaries orange tawny, with a broad black outer margin, on which appear
seme indistinct spots, and a discal set ies of six oblong black spots, unconnected
with the terminal border, and of which the second is very large, whence they
gradually diminish to the abdominal margin.

Underneath the primaries remain chiefly as above. The secondaries have
the base marked with yellow; a short black bar runs along the costal veins
from the base, and there are one or two additional spots on the apical end of
the discal row ; the black outer margin also contains eleven or twelve small
white spots. Expanse 3 — 3-75 inches.

Antennae black, becoming tawny ash-colored on their outer third. Thorax
bla^k, with a jellow dorsal stripe ; wing-covers and collar orange tawny,
dusky yellow beneath ; abdomen brown above, marked with orange tawny on
the upper part of the fi.st two segments, a broad yellow ventral stripe, and two
narrow lateral yellow line's, reaching only to the end of the second ring.

12. EuEIDES ZORCAON, tlOV. Sp.

Male. Upper surface : fore wings black ; four transverse bands, of which the
apical is composed of four oblong spots ; the second crosses the cell near its
extremity, and consists of two dashes above the cell, an irregular nairow one
within it, and a long, gradually tapered stripe below it. Both these bands are
entirely dull ochraceous ; the third rises from the base, follows the first median
veinlet to its middle, up to which point it is orange tawny, is then suddenly
turned above this nervule, and runs nearly to the outer margin ; this latter
portion is ochraceous, and is much compressed near its lower extremity ; the
fourth is orange tawny, and occupies the length of the inner margin below the
subniedian vein.

The hind wings are black, with a broad central orange tawny belt, through
the middle of which passes a black band, sometimes united with the outer
border towards the apex, and usually narrowed towards the abdominal mar-
gin ; there is a row of indistinct spots on the outer margin, especially promi-
nent near the anal angle.

Under surface; disposition of fore wings' markings remains the same, but
they are much reduced, with a consequent increase of the black and blackish-
brown areas ; the costa has a short basal stripe of orange tawny, and there
are three or four small white apical spots.

Secondaries chiefly as on the upper side ; there is an additional transverse
stripe, ochraceous, running from the base nearly to the outer angle, and marked
on its under side at its origin with a white point; two rows of well-defined
white points on the outer margin, of which the interior, numbering fourteen,
are the largest; the outer row contains fifteen. Expanse 3 — 3J inches.

As' may be seen from the foregoing description, this pretty species bears
considerable resemblance to Eueides Cleobxa, Huba. 1 find, however, from the-
examination of a large number of specimens of both, that their differences are
always constant, and such as warrant tbe creation of a separate name for the
designation of this form, which, although doubtless a local race of the Cleobsea,
has become perfectly segregated from the older type ; I have seen no interme-
diate varieties.

13. ACR/EA ORIZAVA, HOV. Sp.

Upper surface glossy bluish-black; primaries with a large transverse yellow
spot, divided by the median vein and its branches into five parts.

Beneath pale ochreous, with the nerves, and streaks between them black ; a
very large central yellow patch on the fore wings, crossed only by black veins ;
base of the fore wing black, that of the secondaries more yellowish. Expanse
2-25 — 2-50 inches. Body and antennae black.

Hab. — Mexico. Coll. Tryon Reakirt.

Closely allied to the A. leucomelas, Bates, of Guatemala, of which it may be
regarded as a more northern modification. It differs chiefly, but constantly,
in size and number of the yellowish spots of the primaries.

Upper surface bright orange-brown; markings of primaries as in .4. Juno,
but much narrower, more clearly defined, and always deep black. Second-
aries with a broad terminal border, containing a series of orange-brown lunules.

Underneath, the markings present no perceptible difference from those of
Juno, but the shades are darker, the silver spots more clearly defined, and the
base of the fore wings much more reddish than in that species. Expanse 2:50
to 2-*75 inches.

The outer margin of the primaries is not so deeply sinuate, nor are the inT
dentations of the secondaries so prominent as in Juno.

15. Euterpe arechiza, nov. sp.

Male. Fore wings narrawer and more sinuate than in Bithys; the brad wings
dentnte. Upper surface brownish- black, traversed by two maculate, white
bands ; the first extends from the outer third of the costa of the fore wings, to
the middle of the abdominal margin of the hind wings, consisting on the first
of eight widely separated spots, on the last the band is broken only by the
dark veins ; the second band is formed of small rounded white spots, running
obliquely from the costa of the primaries to their inner angle, and sub-margin-
ally all equidistant from the border, on the disc of the secondaries ; there
are also some minute white terminal streaks at the apex of the fore wings,
and some marginal ones in the middle of the hind wings' interspaces.

Underneath pale brown, with darker shades between the veins of the hind
wings ; the terminal streaks on the outer margin of the primaries are yellow-
ish. The inner band, of the secondaries is striped narrowly with yellow lines,
beside which there are some small spots and dashes near the base, and the
submarginal and marginal rows, all yellow ; there are also two red basal
patches. Expanse 1-75 — 2 inches.

Body and antenna? as in Bithys.

Hab. — Mexico. Coll. Tryon Reakirt.

A local race of Exit. Bithys. In addition to the differences in ornamentation
, and the shape of the wings, I have found that in Arechiza the disco-cellulars
of the fore wings form but a very slight angle with each other, and the second
subcostal veinlet of the secondaries is invariably thrown off much nearer the
base than in Bithys; the difference in distance being fully eqnal to one-half
the distance between the first and second subcostal veinlets of the latter
species.

;16. Lyo«na catalina, nov. sp.

Male. Upper surface brown, glossed with violet blue, except a broad terminal
border on both wings. Fringes white, cut with brown.

Under surface ash-brown, darkest at the base of the secondaries, more di-
luted on the outer margin of the primaries.

The fore wings have two spots within the cell, one at its extremity, the other
nearer to the base; a submesial sinuated row of six rounded and oblong
spots ; and a submarginal row of six lunes ; all brown, or blackish-brown en-
circled with white ; the outer row is usually incomplete, and sometimes almost
obsolete.

The secondaries have the main portion of the cell occupied by a large
whitish spot, running up to 'he base, and having a rounded black spot in its
centre. Between this and the outer margin there is a broad and similarly
colored belt, formed of confluent sagittae, each of which is preceded by a
rounded black dot, encircled with white, and followed by a narrow black
crescent. Below the third of these from the inner margin, there sometimes
appears an ochreous lune, upon which is impinged posteriorly a brown bar,
tapering gradually to the hind margin. There is another white-ringed black
spot on the costa, above the similar one within the cell. "Expanse 1-13 — 1-20

the largest. Hind wings with a single tail, black, tipped with white. Fringe
brownish ; expanse 1-05 — 1-12 inches.

Underneath whitish ash colored ; a long discoidal streak, and three trans-
verse rows of dark ash-colored dashes, of which the two outer are close to-

the discal bar ; it is slightly sinuated ; each of these rows is composed of six
oblong dashes, all being surrounded by whitish lines from the ground color.

On tke secondaries there are also three transverse maculated bands, con-
taining the same number of spots, but differing in shape; those of the inner
row only are oblong, 'hose of the central being lunulate, and of the outer
rounded ; the two interior spots of the marginal row are jet black, glossed with
some greenish metallic atoms, and are surmounted by two large oraoge yellow
lunes ; a discoidal bar as on the primaries, and three rounded black spots en-
circled with whitish, situated transversely near the base, one on the costa,
another within the cell, and the third on the inner margin ; a similar spot,
sometimes only ash-colored, on the middle of the costa; a narrow terminal

Male. Upper surface very similar to that of Monica, but with more of a bluish
tinge ; a narrow terminal line as in that species, but edged anteriorly with
white, over the whole length of the secondaries, upon which there is only one
black spot; tail double the length of that in Monica; fringe whitish, on the
secondaries cut with black at the ends of the veins.

Underneath there are three transverse bands on each wing as in Monica, but
arranged differently ; the spots of the two exterior on the primaries are almost
confluent, and the inner one is broken into two divisions — the spots in each
running together; the upper consisting of four, and the lower, which is nearer
to the base, of two ; a discoidal bar, and a small spot on the costa between this
and the inner transverse band.

On the secondaries the two outer rows remain the same, having, however,
but one lar;>e black spot, surmounted by a very large pale orange- yellow
lunule ; rarely there are traces of another yellow spot interior to this; the
iuuer band is formed very irregularly, and presents very much the appearance

Prof. Cope remarked that he had made a few observations on some of the
extinct vertebrates of the Mesozoic Red Sandstone, during: an examination
of the specimens preserved in the collection of Charles M. Wheatley, A. M.,
at Phcenixville, Pa.

Rtiytidodon carolinensis (Emmons, usually misspelled Rutiodoii) appears
to be, so far as extant remains are conclusive, a species of Belodon, Von Meyer,
allied to B. plieningeri. One confirmation, the identity of dentition of
the Wiirtembergian and Pennsylvanian species, had been pointed out to him by
C. M. Wheatley. The posterior teeth are lenticular in section, nearly broad as
high, crenate on both eiges ; the anterior cylindrical, slender and coarsely
fluted ; the first represent Eurydorus serridens, Leidy, Pr. A. N. S., Pnila., 1859,
110, and the latter Rhytidodon Emmons.*

Clep>isauru3 pennnsylvanicus Lea, whose affinities have never been
indicated, apparently belongs to the same great type as the preceding : while
its teeth are without pulp-cavity, as pointed out by Leidy, those of the fangs of
Belodon are very small.

He was also enabled to announce the discovery of the first undoubted Laby-
rinthod;m of these beds. The species, which is of considerable size, is repre-
sented by portions of two crania and numerous teeth. It is apparently nearest
Mastodonsaurus (Labyrinthodon) diagnosticus Von Meyer, in the propor-
tions of the cranial segments and sculpture.

The larges#t fragment is eight inches long and eight and one-half wide, and is

a portion of the table of the cranium exhibiting the usual medial depression,
and embracing portions of the postorbital and parbt il bones ; one of the
former is four in. sixl. long ; both are pitted medially (about 3£ pits in an inch)
and marked with short coarse sulci posteriorly. The parietal* are 2 in. 9 I.
wide behind, and four inches wide between the anterior parts of the postorbi-
tttls. On what is probably the posterior part of the interorbital region (a small
part of the posterior margin of the left orbit is preserved) commence two
smooth shallow sulci 1 in. 21. apart, which are probably the posterior extremi-
ties of the superficial channels of the face of the Labyrintuodonts. Between them
the surface is pitted, (4 or 5 to the inch.) The parietal bones are throughout
longitudinally sulcate, (four and one-half to the inch), with obtuse ridges be-
tween. The parietal fontanelle was not discoverable, nor could the form of
the orbits be certainly determined, though they were probably not large.

The teeth are of various Bizes, sometimes two inches long, and more slender
in proportion to the length than those of the Mastodonsaurus j a ege r i and
salamandroides; they are cylindrical, gently curved and acuminate,
without external sulci; of the minuter sculpture noihing could be said, as Prof.
C. had only examined the casts of the surface. In a few weathered sections
the involuted folds of the enamel are well displayed. They areTiot convolute
as in typical Labyrinthodonts, but perfectly straight and convergent to a mi-
nute central vacuity. In a tooth four lines in diameter there appear to be five
principal radii which attain the centre, about twenty which nearly approach it,
and thirty two shorter, none of which measure less than a half radius. These
radii, though exceedingly delicate, may sometimes be seen in longitudinally frac-
tured specimens. The roots exhibit a short conic pulp cavity.

Having observed traces of similar radii in a small fluted tooth having an
oval seciion, much resembling some of those of Belodon (Rhytidodon), but
perhaps Compsosaurus Leidy, it had occurred to the speaker whether these
radii had any connection with the mineral constitution of the teeth. These
were all of black dolomite, the weathered portions, between the radii, white.
Radii and straight veins of other material were pointed out in some specimens
in his collection by Wheatley, as iron and copper pyrites aud silica, but these
were either eccentric or irregular. Inquiry is therefore suggested respecting
the existence of the labyrinthic structure in any of the above genera before
described. The form and sculpture assigned to Centemodon Lea render com-
parison with the new species unnecessary.

The latter may be named Mastodonsaurus durus. The cranial bones on
which it is founded occurred in bed No. 15, a hard black shale, of Wheatley 's
section in Silliman's Journal Sci. Arts, 1861, 45, about 89 feet from the
bottom of the series, while the tooth last described is from near 40 feet
lower down, in Nos. 21 or 22. The Belodon comes from about 35 feet below
the last. .

Geologists have inclined to indentify these beds with the upper Trias or
lower Jurassic. The identification of the Belodon and Mastodonsaurus points
most strongly to the age being that of the Keuper or upper division of Trias.

Belemnocrinus Whitii, M. & W.

Body below the summit of the subradials ovoid subcylindrical, and above
this rather rapidly expanding ; rounded below. Basal pieces very small,
forming a flat subpentagonal disc, as seen from below; anc.ylosed so as to
obliterate the sutures in the specimen examined. Subradial pieces unequal,
three of them narrow, oblong or two and a-half to three times a.s long as
wide, one scarcely more than twice as long as wide, and tlie other narrow be-
low, but nearly two-thirds as wide above as the entire length. First radials
(or at least the only one remaining in the typical specimen) quadrangular,
nearly half as long as the subradials, and wider at the top than the smallest
subradial, narrow below, and widening upwards ; rather deeply sinuous
above across its entire breadth, for the reception of the second radial. Cavity
of the subcylindrical part of the body formed by the subradials, infun-
dibuliform, the wide part above extending down about one fourth of the
way. Anal piece resting upon the slightly concave upper extremity of the
largest subradial piece between two of the first radials ; its form unknown.
Surface nearly smooth or merely granulose. A slightly impressed, distinctly
defined, obovate flattened area, occupies the whole surface of the anal plate, a
small portion of the upper margin of the subradial upon which it rests, and
a larger part of the first radial on one or both sides of the anal piece. Column
and arms unknown.

Length of body to the summit of first radial pieces, 0-57 inch ; breadth of
same at the top, about 0 35 inch ; do. of same at the summit of subradials,
0-25 inch.

This species differs from B. typvs, of White, the only other known species
of the genus, in its proportionally shorter and more oval form below the summit
of the first radial pieces, and the greater expansion above ; also in the greater
inequality in ihe size and form of the subradial pieces ; and in the peculiar
flattened or impressed area in the region of the anal piece. It likewise differs
in having the depression in the upper side of the only remaining first radial,
for the reception of the second radial, proportionally broader ; while the visceral
cavity'occupies near one-fourth the length of that portion of the body formed
by the subradials, instead of only about one-tenth.

The specific name is given in honor of Prof. C. A. White, the accomplished
State Geologist of Iowa.

Subgenus NEMATOCRINUS. M. & W.

StNBATHOCRINUS WACnSMUTHI, M. & W.

General form, when the arms are folded together, elongate cylindrical ; body
below the arms small and basin-shaped, being truncate below for the re-
ception of apparently a rather large column, thence spreading rapidly to the
summit of the first radials, which are horizontally truncated on the same plane
all around their entire breadth above. Arms simple, very slender, equal and
elongated, — rising abruptly from the first radials, seven to each, or thirty-five
in the entire series, and composed each of a single series of pieces, twice to
three times as long as wide, and very like the joints of the tentacula of other
crinoids. (Form and arrangement of the plates of the body unknown.)

1866.]

252 PROCEEDINGS OP THE ACADEMY OP

Height of body, 0-12 inch ; hreadth ahout 030 inch ; hreadth of truncation
of thebase, 0-14 inch; length of arms, known to be at least l-35 inch, but
probable more ; uniform breadth of do., 003.

We very strongly suspect that this little crinoid will be found to be the type
of a new genus hearing somewhat similar relations to Synbathocrinus that
Pterotocrinus bears to Dichocrinus. The fact, however, tliat we have been
unable, after repeated trials, to make out the form and arrangement of the
plates composing the body, has caused us to place it provisionally, for the
present, as a subgenus under Synbathocrinus, with which it agrees exactly in
form and general habit, as well as in having the base composed of three
anchlyosed pieces. Even if it should, however, be found to possess precisely
the structure of Synbathocrinus so far as regards the body below the arm-
bases, we think its very peculiar character of having seven arms (instead of
only a single one) rising directly from the summit of each broa lly truncated,
first radial piece, a sufficient difference to entitle it to rank as the type of a
distinct subgenus, if not indeed of a distinct genus. The fact that all the
species of Synbathocrinus have, so far as known, but a single arm rising from
each ray, renders it improbable that there will be found intermediate grada-
tions in this character when a greater number of species are known.

On one side of the specimen there is some appearance of a small cuneiform
anal piece resting upon the first radials, between two of the arm bases, as in
Synbathocrinus, though we are rather inclined to think this merely the base of
one of the arms folded in between the others so as to be hiddeu, excepting at
its base, by the closing together of the arms on each side. We have counted
this as an arm, and consequently, if it should prove to be an anal piece, there
would be but thirty-four arms, which would leave but six instead of seven
arms in one of the rays — perhaps the anterior one.

We have named this curious species after Mr. Charles Wachsmuth, of Bur-
lington, Iowa, its discoverer, and one of the most successful collectors at that
inter- sting locality.

Locality and position. — Burlington, Iowa, from the upper part of the Bur-

Cyathoceinus Farleyi, M. & W.

Body, below the summit of the first radial pieces, rather deep cup shaped
or subglobose (oblique in the typical specimen), and composed of thick strong
pieces ; under side rounded. Base subdiscodial or depressed basin-shaped,
with a pentagonal outline, composed of unequal pentagonal pieces, very nar-
row at their connection with the column, and widening rapidly to their lateral
angles : all curved upwards at their superior outer extremities, Subradial
plates three or four times as large as the basal pieces, about as wide as long,
convex, and each provided with several irregular wart-like protuberances in
the middle ; four of them hexagonal, and one on the anal side heptagonal.
First radial pieces a little larger than the subradials, wider than high, and
each having a general pentagonal outline, but the superior lateral angles,
which usually curve inwards somewhat between the second radials, are more
or less truncated ; facet for the reception of the second radials large, or occupy-
ing about three- fourths the breadth of the upper side of each piece, and
on the outer side excavated downwards near half the length of the plate,
with a distinct outward slope. First anal piece about the size of the largest
basal pieces, quadrangular in general outline, but having two other inconspicu-
ous angles above, in consequence of small facets for the reception of three
small pieces in the next range, probably belonging to the vault ; resting
squarely upon the upper truncated side of the heptagonal subradial piece,
and connecting on each side with the adjacent first radials, above the horizon
of the summits of which it does not project. Surface smooth or finely
granular, with the exception of the irregular pustulose protuberances on the
middle of each subradial plate. (Arms aud column unknown.)

Height to summit of first radial pieces, 0-bS inch ; breadth, 0-80 inch.

NATURAL SCIENCES OF PHILADELPHIA. 253

This species will be readily distinguished from all others known to us, by
the peculiar little wart-like protuberances on the middle of each smbradial
piece. These are not incipient radial costae, nor properly nodes, but little
irregular pustular prominences like drops of melted wax. Some of them are con-
fluent, while others are distinct and irregularly grouped. They rarely extend
to the margins of the plates, and are almost entirely confined to the subradials,
though there are some faint indications of one or two on the lower half of one
of the first radials.

This species is named in honor of Dr. R. D. Farley, of Jerseyville, Illinois,
to whom the Illinois Geological Survey is indebted for some interesting speci-
mens.

ACTINOCRINUS CALYCUUTS Var. HARDINENSIS.

Although this little crinoid agrees so nearly with Actinocrinus calyculus,
Hall, that we are in doubt in regard to the propriety of considering it a distinct
species, the fact that it comes from the upper part of the St. Louis limestone,
while the A. calyculus holds a position in the Spergen Hill beds, 200 feet be-
low, taken in connection with the usually restricted range of the Crinoidea,
and some slight differences of structure mentioned below, cau-e us to place
it for the present, at least, as a distinct variety from the typical A. calyculus.

In size, form, arm formula, surface markings, and most of its characters, it
agrees well with A. calyculus, from which it differs in the following details,
viz. : Instead of having but one or two interradial pieces to each space, the
first one much larger than the others, and ten or eleven sided, it has four or
five of these pieces to each interradial area, the first of which is not greatly
larger than the others and only six to eight sided. Again it differs in having
six anal pieces instead of but four, while its vault pieces are merely tumid
instead of " acutely spiniferous," excepting a few of those in the depressions
between the arm bases, which support little short spines.

If Batocrinus should be separated from the genus Actinocrinus, this species
should doubtless be placed in it, as it has the general habit of the species of
that group, though its arm bases do not form a quite continuous series, the
intermediate spaces between those belonging to each two adjacent rays being
more deepling sinuous than those between each two of those belonging to the
same ray.

Locality and position. — Hardin County, Illinois, from the upper part of the

The name Calathocrinus was proposed by Prof. Hall in the paper above
cited, for. a group including those curious species of so-called Actinocrinus,
with an obconic body and the summit more or less flattened and greatly spread
out in the form of a ten-rayed star, such as Actinocrinus perumbrosus, A. regalis,
Hall, &c. As the name Calathocrinus had, however, been previously used for
another type by von Meyer, in 1848, it becomes necessary to find another
name for our American group, and we have consequently proposed to call it
Strotocrinns, in the Report of the Illinois Geological Survey (p. 188), now in
press. It includes Strotocrinns perumbrosus, S. regalis, S.glyptus, S. erodus and
iS. lyratus, all of which had been described by Prof. Hall under Actinocrinus.

Genus STEGANOCRINUS, M. & W.
We have proposed the above name in the Illinois Report (p. 195 ) now in press,
for a genus allied to Actinocrinus, with which it agrees in the structure of the
body, but differs in having the rays from the second or third primary radial pieces

greatly extended out horizontally in the form of remarkably elongated, slender,
rigid, arm-like appendages, which are covered in above, all the way out, with
small pieces like these of the vault, and bear the true arms along their sides.
In some species, these long free rays are known to bifurcate once, while in
others they are simple all the way out, so that in the latter the radial pieces
may be said to continue indefinitely in a direct Hue.

Type. — SteganScrinus pentagonus, = (Actiriocrinus pe'ntagonus, Hall.) It
also includes Steganocrinus araneolus, = (Actinocrinus araneolus, M. & W.),
and S. sculptus=Aetinocrinus sculptus, Hall.

Rhodocrinus nanus, M. & W.

Body small, subglobose, with nearly vertical sides which round under below
to the basal concavity. Base very small, and entirely concealed in the concavity
of the under side, by the end of the column. Subradial pieces comparatively
large, forming the under side of the body, and curved up so as to show nearly
half the surface of each in a side view, — hexagonal in general outline, but
probably each with a seventh nearly obsolete angle at the middle of the side
connecting with the base. First radials nearly as large as the subradials, and
regularly heptagonal in form ; second radials rather more than half as large as_
the first, normally hexagonal, but sometimes pentagonal and rarely quad-
rangular ; third radials larger than the second, generally wider than long,
pentagonal, hexagonal or heptagonal, and' supporting upon their superior
sloping sides, apparenly the first brachial pieces, which are not free, but
supported by the first free pieces in the next range ; if there were no farther
divisions of the free rays, there must therefore have been two arms to
each ray, or ten in the entire series. First interradials smaller than the
first radials, and resting upon the truncated upper sides of the subradials,
regularly hexagonal in form, or rarely with the superior angle slightly trun-
cated by tlie middle piece of the next range, so as to form a seventh angle ;
second range consisting of two, or rarely three, rather smaller generally hex-
agonal pieces, above which there are five or six other still smaller pieces
connecting with i lie vault between the arm bases, thus making some eight or
nine interradials to each area ; anal pieces about the same number as1 in each
interradial space, but a little larger in size and differently arranged, there
being three pieces in each of the ranges above the first one, the middle ones
of which continue on up in a right line to connect with the base of the
proboscis above. Vault depressed to the level of the upper side of the arm-
bases, and provided with deep broad furrows or depressions radiating from
near the middle to the interradial spaces, composed of small, irregular, rather
tumid pieces. Opening in the summit of a short, rather narrow lateral pro-
boscis, which rises vertically, with its outer side nearly on a line with the verti-
cal side of the anal area.

All the body plates are convex in the middle, from which point rather ob-
scure ridges radiate to each of their sides. The greater convexity and larger
size of the radial pieces impart a somewhat pentagonal outline to the body, as
seen from above or below. The surface is somewhat granular, and the col-
umn, which is composed near the base of alternately thicker and thinner
pieces, is round arfd pierced by a minute rounded cavity.

Height of body, 033 inch ; breadth of do., 0-35 inch.

Tliis neat little species is evidently closely allied to R. Barrisi, of Hall, from
which it differs in having its body plates merely convex and provided witli
radiating ridges, instead of being "ornamented by sharp, angular nodes and
spines :" also in having eight or nine interradial pieces to each area, instead
of only four to six. Another difference is to be obsei ved in the size of the third
radial pieces, which in R. Barrisi are "minute," while in our species they
are as large as the second radials. We only know the R. Barrisi from the
published description, but we have been assured by M. Wachsmuth, who com-
pared the form under consideration with authentic examples of that species,
that they are easily distinguished.

Genus ONYCHOCRINUS, Lyon and Casseday, 1859.
Although for some time past inclined, like others, to regard the type for
which the name Onychocrinus was proposed, as probably in no respect distin-
guishable from Forbesiocrinus, recent comparisons of some fine examples of
these forms lead us to think that they may be even generically distinct. At
any rate, they are certainly distinguishable upon more constant characters
than those separating Forbesiocrinus from Taxocrinus, which groups we have
elsewhere shown* blend together to such an extent that we do not think they
can be separated more than subgenerically, upon any characters yet pointed
out.

At present we are inclined to regard Onychocrinus as being generically dis-
tinct from Forbesiocrinus and Taxocrinus, but it may possibly form a second
subgenus under Taxocrinus. I* the nature of the column, the number and
arrangement of the basal, subradial and primary radial pieces, Onychocrinus
agrees exactly with Forbesiocrinus : while in other points of structure these
types differ to an extent that could scarcely fail to attract the attention of the
most careless observer, on comparing good specimens of each. In the first
place, Onychocrinus differs from Forbesiocrinus in having the rays from their
origin more divergent, or even income instances extending out horizontally
on the same plane with the base ; while in these extreme cases the long rays,
which are free in to the second radial pieces, and bear the small arms in
clusters at their extremities, have their under sides rounded, and their lateral
margins curved up on each side to meet apparently a series of pieces covering
them over above. According to Lyon and Casseday these forms also have
the vault covered over with solid calcareous pieces — a character not known to
occur in Forbesiocrinus. Another difference is always observable in the anal
side of these types, which in Onychocrinus, instead of being occupied by as
many pieces a| the interradial spaces, or a larger number, as in Forbesio-
crinus, is often so deeply excavated as to destroy the symmetry of the body,
and only occupied by a single row of very small pieces, mounted one upon
another," and resting in a sinus in the upper side of the largest subradial, so
as to look much like a little dwarfed simple arm. On each side of this little
arm-like range of anal pieces, there is a free open space between it and the
adjacent rays, whatever may be the number of pieces filling the interradial
spaces between the other rays. How this range of little anal pieces (of which
there never seems to be more than six or eight) connects with the vault, we
have been unable to determine, as they are always, so far as we have had an
opportunity to see, entirely disconnected from all parts of the body, excepting
the single subradial upon which they rest. We suspect, however, that they
may have formed tne outside of a small lateral proboscis, the inner side of
which was merely covered by a soft dermal integument.

This peculiar character of the anal side, in Onychocrinus, seems to have
been entirely overlooked or misunderstood in the species of this group referred
to Forbesiocrinus — the impression being that the anal plates had been, by
some accident, removed from their place. It is true, we had observed that
the anal area in our F. monroensis and F. Noriooodi is only occupied .by a
slender little finger-like appendage, resting upon the upper side of the large odd
subradial, but, as stated in our remarks in relation to the former species, we
supposed the anal plates had been removed, and that the little rounded finger-
like appendage occupying their place, was only one of the smaller subdivisions
of One of the arms that had been accidentally placed in that position. We
have seen this character, however, in the following species, which we have
in the Illinois Report referred to Onychocrinus, viz., Forbesiocrinus aster iwfor-
mis, F. Wldtjieldi and F. Meeki, Hall ; also in our F. monroensis and F.
Norwsodi, as well as in the new species described in this paper. In the typi-

eal specimen of F. Meeki now before us, the anal space, as may be seen by the
figure in the Iovra Report, is entirely vacant, and also without the little row
of anal pieces. In five other good examples of this species before us, how-
ever, this character is more or less clearly seen.

From the typical forms of Taxocrinus, Onychdcrinus differs in nearly all the
characters distinguishing it from Furbesiocrinus, as well as in having usually
as many interradial pieces as the latter.

As thus separated from b ' orbesiocrinus and Taxocrinus, Onychocrinus still
seems to include two types that may yet be found separable, since Forbesio-
crinus asfericeformis, Hall, and our species diversus described in this paper,
differ from the other species mentioned in having the rays more spreading
and free in as far as to the second radial pieces, with arms clustered in little
bunches at the extremities of the rays far out from the body ; and the free
rays apparently covered above, at least a part of the way out. It is in this
type, if we have correctly understood Messrs. Lyon and Casseday, that they
found the vault composed of solid calcareous fieces, while in the other species
we have mentioned the vault is unknown.

Such species as our 0. diversus, described in this paper, with their long,
spreading, bifurcating rays, and numerous little curled-up arms at their ex-
tremities, must, when perfect, have presented much the appearance of dried
specimens of the existing genus Astrophytwi ; but we cannot agree with the
authors of the genus or subgenus Onychocnmm in the opinion that this type
forms a connecting link between the Crinoidea and the Asteroidea,oi that it
is more nearly allied to the Star-fishes than other crinoids.

Onychocrinus diversus, M. & W.
Body and rays forming together an irregular five-rayed star, the body being
comparatively small, depressed, and distorted by the deeper excavation of the
anal side ; while the rays are large, stout, rigid and free, from the second
radial pieces outward, and extend out horizontally on the same plane with
the base. Basal pieces hidden by the column, or merely shewing as a thiu
ring scarcely distinguishable from the last segment of the column, when the
latter is attached. Subradial pieces comparatively large ; four of them equal,
wider than long, and all pentagonal, with the upper sloping sides longer than
the lateral margins ; the fifth one larger (particularly longer) than the others
and apparently hexagonal. Radial pieces five to each ray, thick and strong,
and after becoming free on the second pieces, curving strongly up on each
side of the ray, so as to make the underside of the free rays distinctly rounded ;
first radial pieces considerably larger than the subradials, of rather unequal
size, wider than long, and heptagonal in form, with probably the exception
of one or two of those on the anal side, which appear to be truncated on one
side, so as to be hexagonal in outline. Succeeding radials diminishing gra-
dually in size, the second and third being wider than long, hexagonal and
pentagonal in form, and the fourth transversely oblong, as seen from below ;
while the fifth is pentagonal, as seen from beneath, having an obtuse middle
angle on the outer side. Beyond this the rays are each composed of a double
series of strong pieces, which are slightly disposed to assume an alternating
arrangement, the two series continuing in close contact laterally to the fourth
pieces beyond the commencement of the double series on the fifth radials, and
then diverging abruptly at an angle of 90° to 100°, to form distinct rounded
branches. At the outer bases of these branches an arm is given off on each
side on the third piece from the commencement of the double series, and bi-
furcate so as to form a bunch of small armlets ; beyond this the two main
divisions of the rays continue on, each composed of a single range of pieces,
until the third piece beyond the lateral arms just mentioned, after which
they are each composed again of a double series of pieces, on the third of
which another arm is thrown off on each side, and bifurcates as before. After

[July,

this each main branch bifurcates without much divergence of the subdivisions,
which are short and divided, so as to form together a bunch of small bifur-
cating arms, thus making altogether apparently not less than several hun-
dred small armlets, or ultimate division of the rays, to the entire series.

The small armlets are all short, and form clusters at the extremities of
the divisions of the horizontally extended strong rays, where they curve up-
wards, and fold together in bunches like tlie fingers of a clenched fist. They
are each composed of a single series of small pieces, which are wider than
long, with a minute patelliform piece at the underside of each, as in Forbesio-
cri?ius.

Interradials three or four to each space, with others above belonging appa-
rently more properly to the vault ; first interradial series hexagonal and rest-
ing in a notch between the upper sloping lateral margins of the subradials.
Anal series consisting of a single free row of very small pieces resting upon the
upper side of the largest subradial, so as to present much the appearance of
an abortive armlet. Surface merely finely granular, with the exception of a
small linear ridge along the middle of each armlet. (Vault unknown.)

Height of body, exclusive of vault, O'SO inch ; antero-postericr diameter,
0*90 inch ; transverse diameter, 1*40 inch; greatest transverse diameter be-
tween the extremities of opposite rays, 4 inches ; length of each of the two
main divisions of each ray, 0-t>5 inch. Column at its connection with base, 0'2S
inch in diameter, and composed of pieces only O'Ol inch in thickness, or ten,
to the tenth of an inch.

This species is related to Onychocrinus asteriformis = (Forbesiocrinus as-
tericeformis, Hall,) but differs in attaining a much larger size, as well as in.
having the two main divisions of each ray widely divergent and proportionally
longer, instead of nearly parallel. Again it differs in having the«subdivisions
and armlets much more numerous ; also in having always five primary radial,
pieces to each ray.

If reliable characters should hereafter be found for separating generically.
Taxocrinus from Forbesiocrinus, it is possible the name of this species would
become Forbesiocrinus (Onychocrinus) diversus, unless equally good characters
may be discovered for separating the three groups generically. It is quite as
probable, however, that Forbesiocrinus and Onychocrinus may be both included
as subgenera under Taxocrinus, in which case the name of our species would,
become Taxocr,nus (Onychocrinus) diversus.

Granatocrinus Shdmardi, M. & W.

Body elliptic-oval, the length and breadth being as about 07 to 44. Base
having the form of a nearly flat pentagonal disc, with modeyately prominent
angles ; columnar facet round, and a little more than half as wide as the base.
Radial pieces lanceolate oblong, or nearly three times as long as wide, most
projecting and slightly narrower at the lower extremity, nearly flat between
the pseudo-ambulacral areas, along the margins of which they project ab-
ruptly in the form of a prominent knife-like keel ; forming five-sixths the en-
tire length of the body, and each obliquely truncated on each side above, for
the reception of the interradials. Pseudo-ambulacral fields very narrow,*fex-
tending the entire length of the body, with almost exactly parallel sides ;
rather convex, and each with a moderately distinct, longitudinal mesial linear
furrow, on each side of which about 65 pore pieces may be counted ; lanceo-
late and supplementary pore pieces unknown. Interradiali p.ioces about one-
fourth the entire length of the body, rhombic in outline, on widest in the
middle, and tapering nearly equally to the upper and lower extremities ; all
rather distinctly sloping inwards from the lateral angles to the middle, so as
to present a notched appearance on the outer surfaces. (Openings of the
summit unknown.) Surface showing, by the aid of a good magnifier, in a,
cross light, microscopic longitudinal lines near the lower end of the radial

sloping sides.

Length, 0*G7 inch ; breadth, 0-44 inch.

At a first glance, this species might be mistaken for fhe common Pentremites
melo, of Owen and Shumard, from which it may be readily distinguished by
several well marked characters. In the first place it is narrower in proportion
to length, and differs in having its pseudo-amhulacral areas prominent instead
of sunken, and bounded on either side by a sharply elevated thin carina ;
■while its interambulacral areas are flat, or even a little concave, towards the
lower part of the body, instead of being convex. It likewise differs in having
scarcely a visible line, instead of a deep furrow along the sutures between the
radial pieces ; while its b3se is much larger, and not sunken, but on a level
with the lower ends of the radial pieces, which are likewise more protuberant
at the lower ends of the pseudo-auibulaeral fields.

In its larger and more prominent base, our species agrees more nearly with
a form described by us as a variety of P. melo, under the name P. melo, var.
projeclus, from which, however, it differs in all the other peculiarities men-
tioned. We now regard that form as a distinct species from P. melo.

Compared with P. elongatus, of Sliumard, which it resembles in general
form, it will be at once distinguished by its greatly narrower and more promi-
nent pseudo-amhulacral areas,. larger radial pieces, and proportionally larger
interradials, which extend up to near the centre of the summit. These two
forms may be regarded as the connecting links between the true Pentremites
(P. Godoni group) and the /-'. melo, or Granatocrinus group. P. elongatus,
however, falls clearly into the former, while the form under consideration
belongs to the melo group.

Named int honor of Dr. B. F. Shumard, of St. Louis, Missouri, who has
given more attention to the Blastoidea than any other person in this country.

Gbanatockinus Norwoodi, 0. & S. ?

Amongst some interesting Crinoids, loaned us for investigation by Mr.
Wachsmuth*, from the Burlington group at Burlington, Iowa, there is a
beautiful specimen, "resembling G. Norwoodi more than any other spe-
cies known to us, with all the numerous little jointed, thread like arms,
and a portion of the column attached. So far as we know, this is the only
specimen of this group ever found with the arms attached. As might have
been inferred from analogy, the arms in this type are apparently, in all re-
spects, exactly as in the true Pentremites. About thirty of them can be
counted arising from each pseudo-ambulacral area, though this is probably not
the entire number, as they are folded together so that many of them may be
hidden. They are very slender, simple, of uniform size, without any percep-
tible, taper, and composed each of a single row of pieces as long as wide, of
which about seven may be counted in the space of O10 inch. We are not
sure they are entire, though it is evident that those attached near the lower
pari of the areas must be at least twice as long as the body. The column
neaT the base is round and composed of thin pieces of equal size, but farther
down there are wider ones, with smaller between at regular intervals.

The body of this specimen is partly hidden by the arms, but as far as can
be determined it is as stated above, much like G. Norwoodi, with the following
differences : In the first place, the parts of its radial pieces forming the inter-
ambulacral spaces are not more than halt as wide as in specimens of G. Norwoodi
of the same size. These surfaces also slope inwards laterally, so as to form
a rather deep groove along the suture between each two radial pieces, instead of
forming a flat area across between the pseudo-ambulacra, as in G. Norwoodi.
Again its pseudo-ambulacral areas are proportionally nearly twice as wide as in
G. Norwoodi, while the portions of the surface exposed are more coarsely granu-
lated than in that species, and the granules differently arranged. As it seems

to be' also less like G. melo, or any of the other species known to us from this
horizon, we suspect it will be found to belong to an un described species, but
as we have not seen the summit, nor base, we are left in doubt on this point.
Should it prove to be new, however, we would propose for it the name G.
Jinibriatus.

ASTEROIDEA.

ScecENASTEK Wachsmpthi, M. & W.
Body flattened, with a regular, distinctly pentagonal outline, the angles being
produced into five rather attenuated rays or arms, which are a little convex
above, and apparently as much as two-thirds as long as the diameter of the
disc, if not more. Disc concave in outline on the outer margin brtween the
rays, and imparting a slightly alate character to the latter, by extending a
little along their inner lateral margins ; like the dorsal side of the rays, com-
posed above of numerous small, slightly convex plates. Dorsal pores mode-
rately distinct between the plates. Plates of the under side of the disk about as
large as the dorsal plates, but flattened, scale-like, crowded, and having the in-
ward imbricating character of the genus very strongly marked. Ambulacra (as
seen in a compressed specimen) very narrow, their adambulacral plates mode-
rately large, oval-oblong, comparatively thin, and very strongly imbricating
outwards or towards the extremity of the rays. Between these two rows of
short, flattened spine-like scales are seen arising from the amlmlacral furrow,
and all inclining outwards toward the outer extremities of the rays. (Other
characters unknown.)

Diameter of disc, 1-22 inch; rays apparently extending as much as 0'90
inch or more beyond the margins of the disc.

This species will be readily distinguished from our S. fimbriatus, from the
St. Louis limestone, the only other known species of the genus, by its smaller
and less convex plates on the dorsal side, as well as by its much thinner, less
oblique and more strongly imbricating row of plates' along each side of the
ambulacra, and particularly by its much narrower ambulacral furrows. We
have not seen any traces of the row of short flattened marginal spines seen
around the disc of S. fimbriatus, nor have the similar little appendages seen
arising in a double row from the ambulacra of the species under consideration
been seen in S. fimbriatus, but it is probable these are generic characters that
exist in good specimens of both species. There may have also been similar
little flattened spines on other parts of the fossil, as" there are some appear-
ances of such little appendages projecting from the transverse sutures between
some of the rows of imbricating adambulacral plates.

We take pleasure in naming this interesting species after Mr. Charles
Wachsmnth, of Burlington, Iowa, its discoverer, to whom science is indebted
for the discovery of many interesting new types of fossils.

the anterior extremity of the hinge; anterior ear very srual), a little convex,
but separated from the swell of the umbo by an oblique, shallow, rounded
impression, — rounded at the extremity, and defined in outline by a very shal-
low marginal sinuosity ; posterior wing large, flattened, triangular, and defined
by a broad, moderately deep rounded sinus, — not equalling in length the most
prominent part of the posterior margin below the sinus — in young shells ra-
ther acutely angular, but more obtuse in adult specimens. Surface ornamented
with numerous linear, radiating costse, smaller than the flattened spaces be-
tween, and crossed by concentric raised lines, so as to form a neat cancellated
style of marking, quite as distinct on the ears (particularly the posterior one)
as on the body of the valve ; radiating costre increasing by intercalation, the
intermediate ones dying out at various distances between the free margin and
the beak, all more or less interrupted at various intervals by irregular, shallow,
concentric furrows of growth. (Right valve unknown.)

Length of the largest specimen, measuring obliquely from the most promi-
nent part of the posterior basal margin to the extremity of the small anterior
ear, 1-55 inch ; do. parallel to the hinge line, 1*41 inch ; height at right angles
to the hinge, 2 inches ; length of hinge and anterior ear, 1*17 inch ; length of
posterior ear, from the beak to its extremity, 0'91 inch.

This rather handsome species has more the aspect of certain Upper Silurian
forms, such as Avicula communis, Hall, than of any carboniferous species with
which we are acquainted, though of course presenting well marked specific-
differences.

It is a little remarkable, that all of the twenty- five or twenty-six specimens now
before us, are left valves, from which fact we may infer that the right valve,
being more fragile, was generally broken to pieces by the waves, before being
imbedded in the sediment. It is also probable that the right valve was less
convex, and more faintly marked than the other, as is usual in shells of this
kind. As we know nothing of the binge and muscular impressions of this
shell, we cannot determine whether it is a Pterinea or a Pteria. If a true
Pterin, and Kleins old pre-Linnaean names are to be retained, the name of our
shell will become Avicula morganensis.

DoLABRA STEKLINGEXSIS, M. & W.

Shell rhombic-cordate, being cordate in outline, as seen in an anterior and
posterior view, and obliquely rhomboidal as seen from either side. Posterior
margin obliquely truncated, with a long slope, which is slightly convex above
and faintly sinueus near the middle ; posterior basal extremity produced
obliquely backwards and downwards, with a more narrowly rounded or sub-
angular outline ; basal margin ascending forward, with a moderately convex
curve, and rounding up more or less gradually into the very short or almost
obsolete anterior side : hinge line short ; cardinal area moderately developed.
Beaks prominent, placed nearly over the anterior margin, strongly incurved,
and compressed antero-posteriorly ; umbonal ridges very prominent, sub-
angular, and extending from the beaks obliquely to the posterior basal ex-
tremity at an angle of about (38° below the horizon of the hinge, thus dividing
each valve into two subequal areas, of which the one behind is flattened or
slightly concave between the ridge and the moderately prominent postero-
dorsal edge, and that in front and below it convex. Surface marked with
concentric striae of growth. (Hinge and interior unknown.)

Greatest length, measuring obliquely from the beaks to the posterior basal
extremity, 2*20 inches ; diameter at right angles to the same, 1*50 inch ; con-
vexity of the two valves when closed, 150 inch.

This species is evidently related to Gjrtodonta Hindi, of Billings (see

geological horizon. It differs, however, in several important specific charac-
acters, being proportionally much more gibbous, shorter, and, in consequence
of its hinge line forming a wider angle with its umbonal axis, distinctly less
oblique. It also differs in having its anterior side much less prominent and
more broadly rounded below the beaks, which consequently have the appear-
ance of being almost terminal. Its beaks are likewise more compressed
antero-posteriorly, and its hinge line shorter. Our specimen does not show
the cardinal area very satisfactorily, though it is evidently moderately well
developed and shorter than in Mr. Hillings' si'eeies.

Until the hinge and interior of this shell can be examined, it is scarcely
possible to determine very clearly its generic character, but on comparison
with Cucullcea angustata, Sowerby, the type of McCoy's genus Dolabra,* and
other more obliquely truncated species, such as C. unilateraUs, Sowerby, C.
amydalina, Phillips, as figured in Phillips' Palaeozoic Fossils, we can scarcely
doubt the propriety of referring it to the genus Dolabra. Some of these
species have much the form and general external appearance of the genus
Cucull<ea ; while Sowerby's figure of an internal cast of the so called C. angus-
tata (Geol. Trans. (2), vol. v. pi. 53, fig. 25), seem to indicate a very similar
hinge. They appear to want the prominent posterior muscular support and
the radiating costas or striae of the more modern species of true Cuculltea, of
which, however, they are evidently palaeozoic representatives.

Mackodon micron em a, M. & W.

Shell rather small, very inequilateral, elongate-oblong, nearly twice and a-
half as long as high, rather distinctly convex in the anterior and central
regions, as well as along tbe oblique posterior umbonal slopes. Posterior
dorsal region compressed above tbe umbonal ridge. Cardinal margin straight,
nearly parallel to the base, and but little shorter than the valves. Ventral
margin long and straight, or but slightly sinuous in the middle, and rounding
up rather abruptly and nearly equally at the ends. Posterior extremity trun-
cated, with a slight forward inclination, sometimes faintly sinuous in outline.
Anterior side very short and rounded. Beaks rather depressed, but rising
moderately above the hinge and somewhat flattened on the outer side ; in-
curved, approximate, and placed near the anterior end. Surface ornamented
with radiating striae, which are oblique, coarse, and rather irregular on the
compressed posterior region, but become gradually less oblique, finer and
more regular anteriorly, so that on the middle and anterior portions of the
valves they are exceedingly minute, very regular, and only visible by the aid
of a go >d magnifier in a cross light. A few moderately distinct marks of
growth are also seen near the basal and posterior margins. (Hinge, area and
interior unknown.)

Length, 0-05 inch ; height (at beaks), 0 28 inch ; convexity, 0 24 inch.

This little shell has much the form and general appearance of Macrodon
carbonaria,=( Area carbonaria, Cox, Kentucky Geol. Report, pi. viii. fig. 8),
but may be readily distinguished, not only by its smaller size and less nearly
terminal beaks, but by the extremely minute size of its radiating striae on
the convex portions of its valves.

Genus PLATYCERAS, Conrad, 1S40.

(Acroculia, Phillips, 1841.)

The germs PI at tic eras was proposed hy Mr. Conrad for a group of palreozoic
shells, Tery generally referred by European authors to the Montfort's genus
Ca'pulu*, published in l&10,=(Pileopsis, Lamarck, 1812.) Mr. Conrad's de-
scription of this g^nus reads as follows : " I propose to group in this genus
the PileOpsi.s tubifer, (Sowerby), P. rehtsa, (Sowerby), Nerita haliotis,
(Sowerby), and perhaps Bellerophon eornuarietes. These shells are suboval or
subglobose, with a small spire, the whorls of which are sometimes free and
soniet mes contiguous ; the mouth is generally campanulate or expanded."*
During the following year, Prof. Phillips proposed in his "Palreozoic Fossils,"
p. 93, the name Acroculia for the same fossils.

In this country Mr. Conrad's name has been generally adopted for these shells,
which is certainly proper, unh-ss they shall be found to agree with the older ge-
nus Capulus, since his name has priority over that proposed by Prof. Phillips.
Although agreeing with those who regard these fossils as being probably dis
tinct from the existing genus Capulus, we believe they are more nearly allied
to that group than is generally supposed to be the case by American palaeon-
tologists. The only reason assigned by Professor Hall for separating them
from the modern genus is, that he had never observed in them any traces of
the peculiar horse- shoe shaped muscular scar so conspicuous in the genus
Capulus.^ We have recently, however, found very similar muscular impres-
sions in two distinct species of this genus, one of which seems to be a variety
of P. subrectum, Hall, from the Keokuk group, while the other is a new
species describ <1 in this paper from the Waverly Sandstone, of Ohio. J In
both of these, internal casts show an elongate oval muscular impression on
each side, connected by a linear band passing around behind. It is also
worthy of ii"te that both of these species belong to the nearly or quite straight
section of the genus, for which Prof. Hall at one time proposed the name
of Orth onychia, § and hence are less nearly like the modern typical forms of
the genus Caputus than the great majority of the Pala?ozoic species.

A careful examination of extensive collections of these shells from our west-
ern pala?ozoic rocks, has also satisfied us that the animal must have been simi-
lar in habit- to Capulus and other types of the family Capulidce, to which they
evidently belong||, in being sedentary shells. This is shown by specimens
found attached to crinoids and other objects in such a manner that the
sinuosities of the lip exactly correspond to the irregularities of the surface to
which they are attached. For instance, we have now before us one of these
shells attached to the side of a Peulreinitrs Godoni, so as to entirely cover one
of the pseudo ambulaeral fields and two of the intermediate areas, and yet the
sinuosities of its lip conform so exactly to the irregularities of the side of the

sureUa, which In- says lias a perforation just anterior to the apex. Although this is merely men-
tioned as a specific character, distinguishing n from an otherwise similar species described in the

Pentremi'te that the fit looks as if it might have been air tight. The corres-
ponding undulations of the lines of growth likewise show clearly that this nice
adaptation of the margins of the lip to the irregularities of the surface of the
Penfremite could not have resulted from accidental pressure when the edge of
the lip was somewhat yielding, since these curves in the marks of growth are
seen to extend up the sides of the shell some distance from the margin, where
there could have been no flexibility.

This habit of attaching themselves to Crinoids, has led some to think the cri-
noids were in the act of devouring these mollusks at the moment when they per-
ished, and that these mollusks constituted the chief food of the crinoids. So far as
our observations go, however, we do not think the evidence sufficient to es-
tablish this fact, since these shells are as often attached to the side of'the crinoid
below the horizon of the arms as to the summit, and hence out of reach of the
mouth, while the conformity of the margins of the shell to the inequalities of the
surface to which they are found attached, rather indicates that they grew there.
The probability seems to be, that like various other sedentary marine animals,
these mollusks, in their very young state, floated freely about until they found
a suitable place to attach themselves. We were at one time inclined to think
there might also be some reason for believing that the a lult shell at least some-
times changed its station, from the fact that iu some instances we observe the
lines of growth indicating strong sinuosities iu the lip during apart of the growth
of the shell, which afterwards became suddenly obliterated, to give place to a
different set of irregularities, as if the animal had changed its stat on and
adapted the sinuosities of its lip to a new surface. This, however, may have
been produced by the lateral expansion of the lip, by which it was brought into
contact with different inequalities as the shell increased in size. We have no
evidence that they possessed the power of excavating a depression in the sur-
face of attachment, as in Amalthea, or of secreting a shelly layer or support
under the foot, as in Hipponyx.

Prof. Hall has' proposed to establish two subordinate groups under this
genus, more or less distinct from the typical forms of Platyceras. These may
be distinguished thus : —

1. Platijciras, Conrad. (Typical.) Shell with apex incurved or spiral ; sur-
face concentrically striated, sometimes radiately plicate, rarely spiuiterous.
Pileopsis iubifer, Sow.

2. Orthonychia, Hall. Shell arched or straight, with concentric striae.
P.'aiycerns subrectum, Hall.

3. Igoceras, Hall. Differing from the last in having the surface cancellated.
Ex. P. plicatum, Conr.

It is, however, often very difficult to separate the species into these groups,
owing to the numerous gradations by which they bleud into each other.

PLATYCEKAS LJEVIGATUM, M. & W.

Shell small, dextral, subglobose, composed of two to two and a-half very
rapidly expanding contiguous whorls, the first of which is minute ; last whorl
forming much the larger part of the shell, evenly convex, and although in-
creasing rapidly in size, not properly campanulate ; aperture nearly circular,
being somewhat straightened on the inner side ; lip not sinuous in any
of the specimens examined ; surface nearly smooth, but showing fine lines of
growth under a lense, where not worn.

Length, 0-55 inch; breadth, 0 38 inch.

This little shell is not very nearly related to any of the other carboniferous
species of this country with which we are acquainted. It will be readily
identified by its small size, rapidly expanding whorls, smooth surface, without
folds or plications, and the non-sinuous, regular outline of its lip. From the
latter character, it would seem to have attached itself only to even surfaces.
In size and the regular smoothness of its surface it is quite similar to

264 PROCEEDINGS OF THE ACADEMY OF

P. bivalve, of White k Whitfield, from the Kinderhook group ; but it may be
readily distinguished by its much more rapidly expanding whorls and conse-
quently larger aperture. It also differs in having the apex of its spire distinctly
sunken below the upper side of the body whorl, instead of nearly even
with it.

Amongst foreign species, ours is perhaps most nearly allied to Pileopsis
angustata, of Phillips (Geol. Yorks. 11, pi. xiv, fig. 20), from which it also
differs in having its whorls much more rapidly expanding, and its aperture
proportionally much larger and more rounded.

Locality and position, — St. Genevieve county, Missouri, and Randolph
County, Illinois ; from the Chester division of the Subcarboniferous series.

Platyceras haliotoides, M. & W.

Shell rather small, ovate, very oblique and depressed ; composed of two very
rapidly expanding, nearly or quite contiguous volutions, the last one of which
is depressed above, narrowly rounded around the dorsal side, and forms nearly
the entire bulk of the shell ; apex of spire on a plane with upper side of the
b»dy whorl ; aperture large, transversely oval, being wider than high ; lip
sometimes sinuous on the outer or dorsal side ; surface with moderately dis-
tinct lines of growth. Exfoliated surfaces sometimes showing apparently
traces of revolving stria?.

Length, 0-73 inch ; breadth, 0-54 inch ; height, 0 41 inch.

This species will be recognized by its very oblique depressed form, and the
narrowly round character of the outer side of its holy whorl, which peculiari-
ties give it much the form of a Huliotis. Its first turn, which is quite small,
seems to have been sometimes free or slightly detatched from the body of the
shefl, and in other examples in contact with it. The marks of growth generally
indicate a rather broad, moderately deep sinuosity of the lip on the dorsal or
outer side.

Locality and position.— Waverly sandstone, fifty feet below the Millstone
grit, Richfield, Summit county, Ohio.

Platyceras pncum, M. & W.

Shell rather under medium size, in adult examples elongate conical and
oblique ; body portion nearly straight, especially on the posterior side ; apex
attenuate, pointed, laterally compressed and curved backwards (without any
lateral obliquity), so as to form a free hook of ab mt half a turn. Aperture
generally a little wider transversely than the antero-posterior diameter, and
usually shoeing a faintly subtrigonal outline, produced by the prominence of
the front, and the flattening of the posterior side of the body. Lip irregularly
undulated, prominent on each side, broadly sinuous behind and provided
with a very deep narrow sinus in front. Surface with the usual undulating
concentric striae crossed on the lower half of the body by small, rather obscure
longitudinal plications, and in front by a larger, but narrow prominent ridge,
upon which the lines of growth make a strong upward curve, so as to indicate
the presence of the anterior sinus during most of the growth of the shell.

Length, 1 inch; breadth (transverse diameter of the aperture), 0-70 inch;
antero-posterior diameter of the aperture, 0"55 inch.

This species is intermediate in size and some other respects between
Plat/jceras acutirostris= ( Capulus acutirostris, Hall) , and Platyct ras equilatera,
Hall. In size and general appearance it is most like the former, though it is
larger and differs in having its apex merely hooked instead of subspiral, as
well as in its prominent anterior ridge and deeper and narrower anterior sinus.
From P. equilatera it is distinguished by its smaller size, narrower and straighter
form (particularly at maturity), less incurved beak, prominent anterior ridge,
deep anterior sinus and portionady smaller aperture. It also wants the
antero-lateral sinuses of the lip seen in the typical forms of that shell.

It is quite evident that the nature and position of the sinuosities of the lip,
as already suggested, in all the species of this genus, were modified to a con-
siderable extent by the nature of the surface to which the animal was attached
during life. A careful examination, however, of large collections of most of
the known American palaeozoic species, shows that there was generally a ten-
dency towards a uniformity in the sinus and the corresponding longitudinal
ridges, when present, iu each species, particularly in those of Carboniferous
age.

Platyceras (Orthonychia) chestere.vse, M. & W.

Shell small, obliquely conical, more or less arched ; apex sometimes
rather attenuate, curved or directed backwards so as to stand nearly over the
posterior margin ; anterior and lateral sides expanding rather rapidly from
near the apex; aperture irregularly subcircnlar ; lip margin more or less
undulated. Surface marked by fine undulating concentric stria? of growth,
and usually with about five rather broad radiating furrows that extend from
the lip to the middle or above, so as to leave between them five broad obtuse
ridges, which are themselves sometimes faintly divided into smaller irregular
costae near the margin of the lip.

Height, or length, measuring from the anterior basal margin obliquely to the
apex, O-b'b' inch ; transverse breadth of aperture, 0-55 inch; longitudinal do.
of same, 0.53 inch.

The most marked feature about this little shell is the rather general pres-
ence of about five radiating furrows extending sometimes from near the apex
to the margin, so as to divide the surface into about five broad ridges, some-
times themselves faintly subdivided. This character is not in all cases dis-
tinctly defined, though the specimens generally show indications of it, while
in some instances it is a very conspicuous feature. In this character it is much
like the Burlington group species, P. quincyense, of McChesney, from which,
however, it is distinguished by its much smaller size, more rapid expansion
and more arcuate oblique form.

It is a specimen apparently of this species to which we have already alluded
as being attached to the side of a Pentremites Godoni. The individual so at-
tached is less attenuate, and has the five furrows less defined than the typical
specimens of the species, but it nevertheless seems to belong to this species.

PLATYCERAS (OrTHONYCHIA) SUBPLICATUM, M. & W.

Shell small, depressed conical, somewhat oblique, rapidly expanding from
a subcentral apex; anterior slope slightly convex; posterior and lateral
slopes straight or a little concave ; aperture subcircular ; adductor muscular
scars finely striated and placed a little above the middle on each side ; elongate-
subovate or sublunate, being a little arched, with the larger end forward and
raised slightly higher than the other, and the posterior ends connected by a
linear depression running around behind ; surface (of casts) with a few large,
irregular radiating folds or plications extending from the margins of the aper-
ture more than half way up towards the apex.

Height, 0'36 inch ; anteroposterior diameter, 063 inch ; transverse, do.,
05b' inch.

We have only seen internal casts of this species, which probably do not give
a very correct idea of the nature of the apex, which in the casts is rather ob-
tuse and merely directed somewhat obliquely backwards and upwards. In
perfect shells it is doubtless pointed and more or less incurved. The plications
of the surface are obtuse and rather obscure in the internal casts. The sur-

face of the shell is prohahly also marked with more or less distinct lines of
growth. The internal casts show very satisfactorily the muscular scars.

This species has somewhat the general form of P. Jissurella, of Hall, hut
is smaller, less oblique, and differs in the possession of large radiating
plications.

Platyceras subrectum, Hall, 1S60. Supplement to Iowa Report, page 1, of

additional sheet; (not P. subrectum, Hall, 1859. Twelfth Report Regents

Univ., N. Y., p. 18.)

Shell straight, more or less elongate-conical, very slightly oblique, attenuate
near the straight subcentral apex, thence expanding, at first gradually, then
more rapidly to the irregularly subcircular or suboval aperture ; lip thin and
irregularly undulated, as if to correspond to an uneven surface of attachment.
Surface with more or less distinct, undulating, concentric striae, and near the
lip stronger marks or lamina? of growth; also generally with a few large,
irregular, undefined, radiating plications.

Length. 1*40 inch ; breadth about l-30 inch.

As remarked hy Prof. Hall, this species varies considerably in the degree of
expansion, some specimens being much more attenuated than others. It is
probable that in very young individuals the immediate apex may have been
curved or subspiral, but in all those we have seen it is straight, sometimes a
little compressed, and only removed from a central position by the slight
general obliquity of the whole shell without any curve. In some respects it
is similar to P. quincyense, of McChesney, from the Burlington division of the
Subcarboniferous series. It differs, however, even when, as is sometimes the
case, it is nearly as strongly plicated as that shell, in its more irregular, less
attenuate form and rougher surface, as well as in not having its folds or pli-
cations forming five regular, broad ridges, more or less flattened and concave
along their middle.

From P. fisnurella, Hall, the shell here described differs in being less de-
pressed or more attenuate, particularly near the apex, which is never oblique
as in that species.

Prof. Hall hail described the species under consideration, in the supplemen-
tary skeet quoted above, but as he by an oversight gave it the same specific
name {subrectum) he had previously applied to another species froui the upper
Heidelberg rocks of New York, it becomes necessary, in order to prevent con-
fusion, that our Illinois species should receive another name, and hence we
propose to call it P. infundibulum.

From the same locality and position with the above, we have a single speci-
men differing from the others in bein<_v greatly more slender and elongated. It
is perfectly straight, somewhat compressed laterally and about twice as long
as wide, being very attenuate above the middle and but slightly expanded be-
low. It is an internal cast, showing no surface markings, but preserving the
transversely elongate-oval muscular scar on each side, apparently connected
by a slender band behind. It is not possible to determine beyond doubt
whether this is a distinct species or only a variety of that described above,
without having more specimens for comparison. Should it prove distinct,
however, we would propose to call it Platyceras (Orthonyckia) extinctor, in
allusion to its resemblance in form* to a candle extinguisher.

Genus METOPTOMA, Phillips, 183G.

From Phillips's figures, and very brief diagnosis of the genu? Metoptoma,* it

* " Patcllifurrn, face under the apex truncate." Qeol. Yoiks, 11, p. 223.

[July,

is evident he intended it to include only those patelliform palaeozoic shells
with the posterior side more or less truncated. Mr. Billings, however, and
some others extend it so as to include circular or oval species, showing no
traces of the posterior truncation, such as were referred by Phillips and others
to Patella. Although it is probable the typical truncated and the oval or cir-
cular species without the posterior truncation represent two distinct genera,
it is perhaps impracticable in our present state of knowledge to separate these
groups, owing to the fact that there are so many intermediate forms ; while
it is very rarely indeed that we can know anything in regard to the interior
of these fossil shells.

Phillips says nothing respecting the muscular impressions of his typical
species, but his figure of M. obloriga, which seems to represent an internal cast,
shows apparently a horse-shoe shaped scar, like that seen in Capulus, Hip-
ponyx, and the all'ed genera. Prof, de Koninck has also shown ( Sup. An. Fos.,
pi. lviii, fig. 1 and 2) this scar very clearly in M. pileus of Phillips, and M.
Solaris, = (Patella Solaris, de Kon.) From these figures it is evident, as ob-
served by Prof, de Koninck, that the open end of the horse-shoe shaped scar is
directed away from the truncated side of the shell, showing that the truncated
side is the posterior instead of the anterior, as supposed by Phillips.

Metoptoma. (Platycekas?,) ujibella, M. & W.

Shell much depressed or patelliform, circular in outline ; apex central or
very nearly so ; sides sloping about equally, with generally a slight concavity,
in all directions ; surface marked by fine lines and obscure wrinkles of growth.
Muscular scar on each side, elongate-oval and somewhat arched downwards,
with a narrower band connecting them behind.

Length and breadth each about 1*70 iych ; height about 0-70 inch.

Although not an uncommon shell, we have never seen a specimen of this
species with the apex entire, though insome of the casts it looks as if it may have
been suddenly projecting and possibly curved. Hence, we are in doubt
whether it may not fall more properly within the genus Platyceras, though it
is much more depressed and expanded than any species of that genus known
to us. As a general thing, the specimens are regularly circular or slightly
oval, and without traces of the peculiar truncation of the typical forms of
Metoptoma, though some of them seem to show obscure indications of it iu the
slightly less prominent outline of the margin on one side.

On one single partly-worn specimen, apparently agreeing in other respects
with the others, there are indications of small, irregular radiating costaa on
the lower half of apparently the anterior side. This may possibly be a dis-
tinct species, but we cannot be sure of this without more specimens for com-
parison, since the typical specimens are mostly internal casts.

Prof. Winched has described, from the Kinderhook beds at Burlington,
Iowa (Proceed. Acad. Nat. Sci., Phila., July, 1865), a somewhat similar
species, but judging from its measurements, it must be distinctly less depressed
than our shell, and differs in being " contracted at the aperture."

Po*LYPHEMOPSIS CHEYSALLIS, M. & W.

ing about two-thirds the entire length and moderately produced below ; suture
distinct ; aperture narrow suboval, acutely angular above and narrowly
effuse below ; inner lip apparently wanting ; columella a little arched and
twisted ; surface showing only very faint traces of lines of growth.

This species has nearly the form of Loxonema Newberry!., of Stevens (an
elongated Macrocfie:lus), but is much smaller, and wants the characteristic
thickening and fold of the columella seen in that species. In size it agrees
more nearly with our Polyphemopsis inornata, frnm a higher position in the
coal-measures at Springfield, Illinois. It has its body volution more produced
below, and less disposed to become subangular around the middle ; while the
slopes of its spire are more convex in outline, owing to the proportionally
larger size of the middle whorls. This latter character gives it the chrysalis-like
form that suggested the specific name.

Naticopsis Littonana, var. genevievensis.

Natica Littonana, Hall, 1856. Trans. Abany Inst., vol. iv. (p. 30, of
extract.)

The shell we here place provisionally as a variety of Natica Littonana,
Hall (a true Naticopsis), agrees almost exactly with authentic examples of
that species from the original locality, excepting that it attains some six or
eight times the size of the largest of the Indiana specimens, and yet has the
same number (four) of whorls. Some of the specimens have the oblique
lines rather more distinctly defined around the upper side of the body whorl
than we have seen on any of the typical examples of Naticopsis Lit-
tonana, but tli is might be expected from their much larger size. These lines,
however, are quite distinct on some of the unworn specimens of N. Littonana,
from Spergen Hill.

Our specimens of the shell under consideration show the inner lip to be
little thickened and very smooth, while the columella is moderately flattened.
The surface is quite smooth up to the area below the suture, marked by the
oblique, very regular stria?, which terminate very regularly and abruptly at
their outer extremities. In worn specimens these lines, however, are entirely
obsolete. It is not impossible that this may prove to be a distinct species
from the N. Liltununa, though we here place it provisionally as a variety
of that species.

Genus ANOMPHALUS, M. & W.

Shell depressed, sublenticular, imperforate, smooth and without a spiral band ;
volutions somewhat embracing above, and each hiding all the preceding ones
below ; aperture wider thau high ; peristome not continuous ; labium simple
and without a notch or sinus, projecting forward above ; labium a little sinu-
ous and slightly spreading in the more or less impressed umbilical region.

The type for which this genus is proposed is a little shell having somewhat
the aspect of a Rotella, but wanting the callus seen filling the umbilical im-
pression in that genus. At a first glance it might be mistaken for a small
Straparollus, but on examining the underside it is seen to be entirely without
an umbilicus, though slightly impressed in the middle ; while its lip continues
in below nearly to the centre, where it is abruptly deflected upwards, becomes
a little thickened, somewhat spreading and more or less sinuous, much as we
see on each side of some species of Bellerophon.

We have little doubt but this genus belongs to the Rotellidoe, which was
certainly represented during the deposition of the palaeozoic rocks, apparently
even by the typical genus Rote/la, — the well known Devoniau Ilelicites helicuii-
J'ormis of Schlotheim being apparently a true Rotella.

spire scarcely visible above the body whorl in a side view ; volutions three
and a half to four, increasing moderately in breadth, last one sloping with a
moderate convexity between the suture and the periphery, and slightly ex-
cavated in the umbilical region ; suture not impressed ; aperture transversely
suboval, being rounded on the outer side and straightened on the lower half of
the inner side, but modified by the return of the body whorl above. Surface
showing scarcely any traces of lines of growth, even under a good magnifier.

Genus Mickodoma, M. & W.

Shell small, rather thick, conical, imperforate, composed of flattened whorls,
the last one of which is more or less angular around the midille and little pro-
duced below ; aperture about as high as wide ; outer lip simple, straight, and
oblique in outline ; columella without folds or plications ; inner lip thin and
slightly reflexed at the base of the columella. Surface with revolving nodu-
lar ridges.

We have for several years past had under consideration a number of good
specimens of the little shell, for the reception of which this genus is proposed,
but delayed publishing a description of it because we were iu doubt respect-
ing its generic relations. At afiist glance it presents much the appearance of
a Murchisonia, or a rather elongated Pleurotom tria ; but even where the outer
lip is broken away, so that the sinus characteristic of these genera could not
be seen if it had existed, an examination under a good lense shows
that it has no revolving band, and that its lines of growth are without the
peculiar curve in passing across the whorls, so invariably accompanying the
sinus in the lip of Murchisonia and other shells of that type. It also resembles
some of the small, short species of Turritella, but in addition to its shorter,
trochiform outline, its outer lip presents an obliquity and straightness of out-
line that imparts a peculiar appearance to the aperture, not seen in that genus.
From our genus Orthonema, with which it is associated in the rocks, it differs,
not only in its shorter trochiform outline and nodular revolving ridges, but
also in its very oblique lines of growth and the consequent obliquity of its
outer lip.

It is not easy to determine the family affinities of this type, but it may pos-
sibly belong to the Littorinidce. It is probable that Pleuratomaria serrilimba
and P. biseriata, of Phillips, referred by Prof, de Koninck to the genus Troc/ius,
may belong to this genus. We doubt the existence of the genus Trockus,
as properly restricted to such types as the recent T. niloticus, Linnaeus, during
the Carboniferous epoch.

MlCRODOMA CONICA, M. & W.

Shell rather elongate conical or subtrochiform ; volutions seven, flattened
on a line with the slope of the spire, increasing rather gradually in size— last
one not much produced below the mesial angle, where it is only marked by
minute striae of growth ; suture rather deep ; aperture quadrato-suborbicular.
Surface ornamented by three distinct, revolving, nodular ridges, the largest
and lowest of which occupies the mesial angle of the body whorl, and passes
around immediately above the suture of the whorls of the spire, while the
upper one occupies the tipper margin of all the whorls just below the suture,
and the third one passes around midway between the others. Lines of growth
small and crossing the flattened slopiug sides of each whorl obliquely, so as
to indicate a distinct forward extension of the outer lip at its connection with the
body whorl above. Nodes of the revolving angles small, closely and regularly
arranged on the different ridges, so as to form oblique rows parallel to the
lines of growth.

Length, 0-21 inch ; breadth, 0-12 inch ; apical angle, 36°.

This species seems to be much like Pleuratomaria serrilimba, of Phillips,
judging from his figure, (Geol. Yorks. 11, pi. xv. fig. 30) ; but it is utterly im-
possible to make satisfactory comparisons with species so briefly described aud
poorly figured, without having access to authentic specimens.

Locality and position. — Macoupen County, 111. Lower Coal Measures.

Orthonema conica, II. & W.

Shell elongate conical, thin. Volutions (in adult shells) about nine, flattened
nearly on a line with the slope of the spire, or but slightly convex ; lower
ones sometimes a little projecting at their lower margins immediately above
the suture ; last one distinctly angular around the middle, and but modera'ely
produced below the angle, where it is a little convex. Umbilical region not
indented. Suture generally well defined between the lower whorls, aud merely
linear above. Aperture rhombic subquadrate. Surface showing, under a
magnifier, small, very slightly oblique lines of growth, which are sometimes
crossed on the middle of the flattened outer slope of the body whorl, by very
faint traces of two revolving ridges, and below the angle, on the under side.
by traces of another revolving ridge.

Length, 0-70 inch ; breadth, 0-30 inch ; apical angle a little convex on its
slopes, divergence about 30°.

This species will be readily distinguished from our O. Salteri, from the
same locality and position, by its larger size, smaller number of whorls,
greater apical angle, and particularly by never having the two linear revolv-
ing ridges just below the suture, so characteristic of that species. As men-
tioned in the description, it sometimes, though rarely, shows traces of two
very obscure revolving ridges on the flattened part of the body whorl, but
these are midway between its principal angle and the suture, while those on
O. Salteri are always very distinct, and placed just below the suture. The
principal angle on the body whorl of O. Salteri is also much more distinct,
being a true carina.

From the several species of Pohjphemopsis of our coal-measures, such as our
P. inornata, P. peraci/ta, &c, which it somewhat resembles, this species will
be distinguished by its angular body whorl ; and particularly by not having
this whorl produced below, and its columella curved outwards and trunca-
ted, so as to produce the peculiar effuse character of the base of the aperture
seen in that genus.

TROCHITA ? CARBONARIA, M. &. "W.

Shell small, depressed trochiform, or broadly conical, about twice as wide
as high, circular in outline as seen from above ; periphery alate and very
sharp, not serrate or crenate ; apex central, mammillated ; volutions about
five, flattened or a little concave in the middle ; suture merely represented by
a nearly obsolete line scarcely visible without the aid of a magnifier ; aper-
ture unknown ; umbilicus small, infundibuliform. Surface smooth on the
upper whorls, but showing moderately distinct, extremely oblique lines of
growth on the last turn.

Breadth, 035 inch ; height, 0-17 inch ; apical angle about 105°.

This little shell resembles quite nearly Trochella prisca, of McCoy, from the
Carboniferous limestone of Ireland ; from which it differs in its much smaller
size, and moderately distinct lines of growth. So far as we know, it is the
first shell of this type ever found in our American Palaeozoic rocks. Its alate
margin seems to project as a sharp rim around the periphery, and the general
aspect of the shell is very like that of the genus J'horus, though we have been
unable to see any indications of foreign bodies being attached to the margin.
We are not sure, however, but we would be nearer right in calling it Phorus
carbonarius, or Onustus carbonarius.

Platyschisma hemcoides, Sowerby? (sp.)

The specimens before us agree so exactly with the figures and descriptions
of Sowerby's Ampullaria (Globulus) helicoides, from the English Mountain lime-
stone, that we are completely at a loss to find any characters by which it can
be distinguished. The largest of them are somewhat smaller than the aver-
age size of English specimens, and none of them are so depressed as the form
for which Phillips proposed the name Natica elongata ; their outline being
more nearly like Sowerby's fig. 2, pi. 522, Min. Con. On comparison with
specimens of the Belgian form from Tournay (usually referred to Sowerby's
species), which they never equal in size, and which seem to us probably dis-
tinct from the English species, they are found to differ in having the whorls
less rounded above, and the revolving strife within the small umbilicus coarser.
The surface is quite smooth, the apex rather obtuse, and some of the speci-
mens show indications of the faint sinus in the outer lip, which has caused the
European specimens to be sometimes referred to the genus Pleurotomaria.
There are no traces of a spiral band, however, and some individuals seem to
have had no notch or sinus in the lip.

Pleurotomaria conoides, M. & W.

Shell small, regularly conoid-trochiform. longer than wide, the breadth be-
ing to the length about as five to six. Volutions five or six, increasing regu-
larly and rather gradually in size, — all obliquely flattened nearly parallel
to the slope of the spire, though the lower margin of each projects at i lie
suture slightly beyond the upper edge of the succeeding one below ; last one
angular around the periphery at the base, and flattened on the under side at
less than a right angle to the oblique slope above, but rounding abruptly into
the minute umbilical perforation within. Aperture rhombic quadrangular,
with nearly equal length and breadth ; inner lip straight and parallel to the
axis of the shell below, but curving out abruptly at its base. Surface orna-
mented with small, regular, oblique, arching sfria3 on the upper sloping sides
of the whorls, and minute sigmoid lines, crossed near the periphery by faint
traces of a few revolving stria?, on the under side of the body whorl. Spiral
band narrow, located at, or slightly above the periphery of the body volution,
and passing around its own breadth above the suture on the whorls of tbe
spire ; margined above and below by a raised line.

Length, 0-27 inch ; breadth, 0'23 inch ; apical angle regular, divergence
about 50°.

This species belongs to the trochiform section of the genus, including Pleu-
rotomaria obtusispira, and P. Riddellii, Shumard ; P. turbiniformw, M. & W.,
and P. Missouriensis, Swallow, (sp.) It differs from all these shells, however,
in being much smaller, although composed of about the same number of
whorls ; while it also differs from them all excepting the P. obtusispira in hav-
ing no revolving striae on the upper side of its whorls, and from that species
in having a more elevated spire, and rather coarse, instead of " extremely fine,
stria? of growth " on the upper slope of its whorls. In form and general ap-
pearance it resembles quite nearly Trochus coniformis, de Koninck (An. Foss.
pi. xxxvii. fig. 4, a, b,)* but differs in wanting the spiral striae, and of course
in the possession of a distinct, but narrow spiral band.

*This snell resembles so closely in form, surface markings and general outliue, several of our
American Carboniferous species of Pleurotomaria, that in case it had been described by a lees ex-
perienced palaeontologist than I'rof. de Koninck, we should have suspected it to belong to that
genusinstead of being a true Trochus. In one Pleurotomaria turbiniformis, for instance, and tbe
beautiful species described by Prof. Swallow under the name Trochus Missouriensis, the spiral
band is so very narrow and inconspicuous as to be easily overlooked, when the margin of the lip
is broken away.

Pleurotomaria Coxana, M. & W.

Shell attaining a large size, obliquely conoid-subtrochiform, longer than
wide; spire turreted, forming rather more than half the entire length. Vo-
lutions six to seven, convex, very prominent or obtusely subangular below the
middle, at which point those of the spire project out over the suture ; all flat-
tened or slightly concave above, with an outward slope of about 35° to the
axis, from the suture to the most prominent part, where the spiral band is
placed ; below this the underside is rounded convex to the small umbilical
perforation. Suture strongly defined by the convexity of the whorl just
above it. Aperture subquadrate. approaching subcircular in adult shells.
Surface ornamented by exceedingly fine, regular lines of growth, that run
very obliquely backwards, with a slight forward curve in passing down the
sloping upper side from the suture to the spiral band at ihe most prominent
part of the whorls ; between this and the umbilical perforation below they
make a backward curve. Casts also show some traces of much stronger re-
volving lines in the umbilical region.

As is not uncommon in species of this type, the divergence of the apical
angle varies considerably with age, being greater in young than adult shells.
In internal casts there is a moderately distinct umbilical perforation, which
seems to be very small, or nearly closed in specimens retaining the shell.
The lines of growth are exceedingly fine and regular, without any traces of
revolving striae, excepting near the umbilicus, and we are not sure they really
exist there, as only traces of apparently such lines have been seen.

This shell will be readily distinguished from all of those known to us, ap-
proaching it in size, such as P. tabulata, Conrad, and P. su/jscalaris, M. & W.,
by its more oblique form, more sloping and less angular whorls, as well as
by the absence of any traces of revolving stria? on the upper slope of its whorls.

The specific name is given in honor of Prof. E. T. Cox, of New Harmony,
Indiana, to whom we are indebted for the use of the best specimen of the spe-
cies we have seen.

Plecrotomaria spironema, M. & W.

Shell rather under medium size, subglobose, its length and breadth being

of the spire convex ; the last one forming more than four-fifths of the entire
length, and as much as nine-tenths the entire bulk of the shell, — rounded
regularly from the suture above to the umbilical region below, excepting
near the aperture, where it is a little more prominent below than above the
middle. Suture well defined. Aperture subcircular in general outline, but
rather strongly modified above the middle on the inner side, by the return of
the body whorl. Inner lip slightly thickened a.nd deeply arcuate below, but
wanting or exceedingly thin above the middle of the aperture ; columella tortu-
ous, with a slightly impressed furrow at the outer margin of the inner lip,
but without an umbilical perforation. Surface ornamented with regular, dis-
tinct revolving striae, crossed just below the suture by short little regular node-
like folds, confined to the narrow space between the suture and the spiral band ;
similar, but smaller, more crowded and longer curved wrinkles also radiate
from the umbilical region, on the under side of the body whorl. Lines of
growth obscure on all the specimens examined. Spiral band flattened so as
to be even with the general surface, nearly smooth, and placed half-way be-
tween the middle of the body whorl and the suture above, or about once and
a half its own breadth below the suture.

aperture, 0*25 inch; breadth of do., 0'23 inch ; apical angle convex, diverg-
ence, 90°; breadth of spiral band at the aperture 007 inch.

This species is nearly related to P. Beckwithana of McChesney (New Palaeo-
zoic fossils, p. 61), with which we supposed it to be identical from Prof.
McCbesney's description, until we had an opportunity to compare it with
good examples of the P. Beckwithana from the original locality. On com-
parison with these, we find our shell to be readily distinguished by having
its spiral band located midway between the middle and upper margin of the
body whorl, instead of passing around the middle of the outer side. It like-
wise differs in showing no traces of revolving stria? on the spiral band, and
in having small wrinkles crossing the revolving striae on the under side of the
body whorl, while the little wrinkles around the upper edge of the whorls
are stronger and shorter than in P. Beckwithana. Again there is a differ-
ence in the revolving striae, those of our shell never having an intermediate
smaller one between two larger ones, as is generally the case with those of
McCbesney's species.

The close similarity between these two species, both in form and ornamen-
tation, shows the necessity for great care and precision in drawing up de-
scriptions of species, even where they may be widely different from all known
forms ; since we often find, in such cases, that other species are afterwards dis-
covered that cannot be distinguished by the original description from the
forms first described. Every word in Prof. McCbesney's description, except-
ing what is said in regard to the starting point of the spiral band, would ap-
ply equally well to our species. It is true, he gives the number of whorls as
four or five, while in our shell they may be described as numbering five or
six, but of course little reliance can be placed upon a difference of only one
whorl, where they are all counted to the extreme apex.

Pleurotomaria valvatiformis, M. & W.

Shell minute, depressed, or about twice as wide as high ; volutions three
and a half to four, regularly rounded, and increasing rather gradually in size;
suture well defined in consequence of the convexity of the whorls ; umbilicus
proportionally small or closed ; aperture suborbicular, being a little straighter
on the inner side. Spiral band nearly or quite even with the surface of the
whorls, and placed on the middle of their outer side. Surface smooth, as
seen without a magnifier, but presenting traces of microscopic revolving striae,
in a good light under a strong lens.

Height, 0-04 inch; breadth, 008 inch.

This is by far the smallest species of the genus we have ever seen, and if it
were not for the fact that we find so many specimens of it not exceeding the
dimensions given above, we would think might be a young shell. This, how-
ever, taken in "connection with the absence, so far as yet known, of any spe-
cies in our carboniferous rocks agreeing near enough for this to be its young,
are sufficient reasons for believing it to be an adult shell. It is more nearly
like our P. micronema of this paper than any of its associates with which we
are acquainted, but in addition to its vastly smaller size (although having
nearly the same number of whorls), it differs in being much more depressed,
and in having proportionally much more slender whorls ; while its spiral
band passes around the middle of the body whorl, instead of between the
middle and the upper margin. In the position of its band it is nearer like
P. Beckwithana of McChesnej, but differs so widely in size, and other charac-
ters, as to render a close comparison unnecessary.

MURCHISONIA INORNATA, M. & W.

Shell very small, conic subovate ; axis imperforate'; spire short (for a Mur-
chisonia). Volutions six, convex, increasing rather gradually in size, last one
forming more than half the entire shell, most prominent around the middle,
but not even obtusely angular, a little produced below ; suture impressed.
Aperture slightly oblique, subovate in outline, being angular above, and
rounded and apparently faintly effuse below. Spiral band not distinguishable
from the general surface of the whorls, excepting from the curve of the minute
lines of growth, as seen by the aid of a magnifier ; apparently of moderate
breadth, and placed about half-way between the middle aud upper side of the
body whorl, passing around near the middle of those of the spire. Surface
appearing nearly smooth to the eye, but when examined with a magnifier,
seen to be ornamented with small obscure revolving striae, most distinct be-
low the middle of the body whorl ; crossing these, traces of very minute lines
of growth may be seen, by the aid of a good lens in a favorable light, curving
strongly backwards as they approach an undefined spiral band.

Length, 0-22 inch ; breadth, 0-13 inch ; apical angle about 38°.

This is one of those intermediate forms, that might, so far as can be deter-
mined from the shell, be referred with almost equal propriety to either Mur-
chisonia or I'ieurotomarin. Although we have placed it in the former genus,
we are not sure but we should call it I'leurotomaria inornata. It will be readily
distinguished from all the little species of either of these genera known to
us, that have neither costate nor carinated whorls, by its nearly smooth
surface and obsolete spiral band. Excepting in its much smaller size, and less
produced body whorl, it has somewhat the look of Murchisonia melanoides, de
Koninck, (An. Foss. pi. iii. sup. fig. 14, a, b,) but the more produced lower
part of the body whorl of that shell gives its aperture a different form, while
it has a well defined spiral band occupying a lower position on the whorls,
and no traces of revolving lines.

CEPHALOPODA.

Nadtilus [Trematodiscus] sulcatus, Sowerby ?

Amongst other specimens from the Chester group of St. Genevieve County,
Missouri, we have several examples of a small Nautilus, agreeing so nearly
with Sowerby's N. sulcatus that we are strongly inclined to believe it identi-
cal with that species. It attains about the same size, has a similar umbilicus,
the same number of whorls, with the same number of furrows and intermedi-
ate ridges on each side, and like that species has a small, nearly central si-
phon ; while it also agrees in the size and flexures of its lines of growth, as
well as in the variations it presents. The only differences we can see are
that our shell seems to have the whorls generally more compressed, and its
furrows and ridges sometimes more obsolescent on the outer volution of the
larger specimens. Still it generally agrees quite as nearly with the typical
forms of that species, as those usually referred to it by the most reliable
European authorities, and even more nearly than many of these do with each
other. (Prof, de Koninck's description of N. sulcatus agrees exactly with our
shell.) Its lines of growth make so strong a backward curve in crossing the
slightly concave, rather narrow periphery, that we were at first inclined to
think it a large Porccllia, but a closer examination soon satisfied us that it is
septate, and provided with a small, nearly central siphon. In short, it is a
typical example of the group for which wepropoSed the subgeneric name Tre-
matodiscus.

We are not aware of this species having been previously identified in Ame-
rica.

Nautilus (Cryptoceras) rookfordensis, M. & W.

As the only specimen of this shell we have seen consists of not more than
half of a volution, we are left in some doubt whether it is a Cryptoceras or a
Gyroceras. Its volutions were evidently not embracing, as they are not at all
concave on the inner side, but rounded all around, so as to present a slightly
oval, or subelliptic section, the transverse diameter of which is to the dorso-
ventral, as 132 to 110. The half volution curves around an umbilical cavity
apparently rather more than half as wide as the greatest dorso-ventral diame-
ter of the volution at the same point. The siphon, although not quite in con-
tact with the dorsal side, is so near it as to give the internal cast the appear-
ance of having a small deep dorsal lobe. The septa are distant, measuring,
on the dorsal side, about two-fifths the dorso-ventral diameter of the whorl
at the point of measurement, and their 'edges pass almost directly around
the whorls. (Surface, number of whorls and aperture unknown.)

Length of a half turn, including a small portion of the last chamber, meas-
uring around the dorsum, 3-78 inches ; greatest transverse diameter at the
larger end, 1-80 inch ; dorso-ventral do., 1-60 inch.

It is probable, judging from analogy, that the lip of this species, in entire
specimens, will be found to be pinched out or projecting laterally on each ven-
tro-lateral margin of the aperture, as in some other species of this type. We
know of no other species with which it is liable to be confounded.

Locality and position. — Goniatite limestone, of the Kinderhook division of
the Subcarboniferous series, at Rockford, Indiana.

Note. — In the August number of the Proceedings of the Academy for 1865,
p. 165, we proposed the name Evactinopora, for a curious radiated body, evi-
dently belonging to the Polyzoa, from the carboniferous rocks of Missouri.
Since that time, farther comparisons lead us to think this fossil possibly
not generically distinct from Conodictyum of Miinster. If so, the name of our
species will of course become Conodictyum radiatum. It is a little remarkable,
however, that the known species of Conodictyum are from Jurassic rocks.

Prof. Cope exhibited the remains of a gigantic extinct Dinosaur, from the
Cretaceous Green Sand of New Jersey. The bones were portions of the
under jaw with teeth, portions of the scapular arch, including supposed
clavicles ; two humeri, left femur, and right tibia and fibula, with numerous

phalanges, lumbar sacral and caudal vertebrae, and numerous other elements
in a fragmentary condition.

The animal was found by the workmen under direction of J. C. Voorhees,
Superintendent of the West Jersey Marl Company's pits, about two miles
south of Barnesboro, Gloucester Co., N. J.

The bones were taken from about twenty feet below the surface, in the top
of the "chocolate" bed, which immediately underlies the green stratum
which is of such value as a manure.

The discovery of this animal filled a hiatus in the Cretaceous Fauna, re-
vealing the carnivorous enemy of the great herbivorous Hadrosaurus, as the
Dinodon was related to the Trachodon of the Nebraska beds, and the Mega-
losaurus to the Iguanodon of the European Wealden and Oolite.

In size this creature equalled the Megalosaurus bucklandii, and with
it and Dinodon, constituted the mo^t formidable type of rapacious terrestrial
vertebrata of which we have any knowledge. In its dentition and huge pre-
hensile claws it resembled cjosely Megalosaurus, but the femur, resembling
in its proximal regions more nearly the Iguanodon, indicated the probable
existence of other equally important differences, and its pertinence to another
genus. For this and the species the name of Laelaps aquilunguis was
proposed.

The following were some of the special characters.

Mandible. — Two portions, one from the anterior pari of the ramus. The
latter measure three inches in depth from the outer alveolar border, which is
a little more elevated than the internal, and 1.5 in. in thickness at the frac-
tured edge. A longitudinal series of vascular foramina extends along the
middle of the external face. The teeth are implanted in deep alveolae, had
oval compressed fangs, and lenticular compressed crown, with large pulp
cavity. The crown was elongate, subacute and slightly curved backwards,
minutely striate, and strongly serrate on both edges to near the fang ; this
portion of a young tooth yet in the alveolus measured 2Jin. long and ll-16ths
in transverse diameter.

Left Femur. — The great external trochanter massive and elevated to the
plane of the head, from which it is only separated by a slight depression, and
to which it is slightly transverse. The head not projecting far beyond shaft,
and without constriction below. In Megalosaurus the head is produced be-
yond a kind of neck, and the great trochanter is much smaller and lower
down, differing thus from the other known Dinosaurs. The femur of Lae-
laps is therefore much flattened from before backwards above, but is cy-
lindrical and curved backwards medially. Distally the condyles are more
like Megalosaurus than Hadrosaurus or Iguanodon, yet quite different from
the first. The length of the inner condyle greater than the transverse ex-
tent of the two, the popliteal groove deeper and the trochlear aspect more
concave, leaving a narrower connection between the condyles. The inner
condyle was much narrower and both more projecting than in Megalosaurus.
The third trochanter is small, and lower down than in any known Dinosaur,
being removed less than one-third the length of the femur from the inner
distal condyle.

lozenge-shaped, is cuneiform, the inner wide extremity oval rounded. In-
ner transverse breadth of proximal head one-fourth total length. Anterior
ridge very strong, much incurved, disappearing at between the proximal
fifth and fourth of length ; internal ridge on proximal half, strong, but not
reaching condyles. Posterior condyles separated by a deep notch, inner
larger than outer ; (outer larger, Megalosaurus bucklandii). Shaft much
compressed from before backwards, and distal articulation at right angles to
proximal, concave on its interior half.

These long bones are hollow, with thick walls of dense bone ; diameter of

Fibula. — Twenty-three inches preserved, proximally concave and dilated ;
condyle curved, narrow acuminate oval, in profile concave, then rounded
descending; length 6 in., median breadth 1.75 in. Just below the condyle
on the inside is a deep concavity with abrupt superior and lateral walls. Shaft
less flattened below, but slender, reaching a width of 1^- in.

Humerus. — Both are preserved, but lack the distal condyle ; about half the
olecranar fossa of one remains, furnishing an indication of the breadth of that
extremity. They are proximally much dilated, having a very strong postero-
external ala and a shorter antero-internal dilatation. They are not half the
length of the femur ; the shaft is flattened antero-interually. Of the proxi-
mal articulating surface the proper condyle is lost, but a narrow surface
continuous with it externally does not extend further out on the dilation than
opposite to the middle of the shaft. Olecranar fossa large and well marked,
not near to penetrating ; medullary cavity of shaft relatively smaller than in
the bones of the leg.

These humeri are relatively shorter than in Hadrosaurus and Iguanodon,
and the external alae do not pass so abruptly into the shaft as in them.

? Clavicles. — Two lateral elements are nearly similar to those identified by
' Owen in Iguanodon with clavicles, and by Leidy in Hadrosaurus with the
pubes. Their disproportionate size, as compared with the humeri in Lae-
laps, renders their recognition as clavicles difficult ; they are very unlike
usual forms of pubes. Each has a gentle sigmoid flexure, and a subtrigonal
section They are flattened at the inner extremity and dilated with a margin
at right angles to the shaft; the whole extremity is not preserved; the flat-
tened portion is hollow, while the shaft is entirely solid. Length 18.5 inches.
Phalanges. — No. 1. An ungueal phalange of remarkable size and destruc-
tive use. The depth at the proximal articulation is about the same as in
Megalosaurus bucklandii, (two inches without inferior tuberosity) but
the length is considerably greater. Form everywhere compressed, especially
at tip, rounded above. Below the articulating surfaces is the point of in-
sertion of a large flexor tendon, a flattened subglobular process, separated
by a groove except in front. The groove extends on each side distally on
the middle, to the tip. The general form is not unlike that of a rapacious
bird, but is more compressed.

Vertebrve. — No cervical or dorsal vertebrae were preserved ; very few lum-
bars, a fragment of two of the connate sacrals and numerous caudals were
all as yet in Prof. C's possession. All are much constricted medially, or hour-
glass shaped, the centrum cylindrical in section throughout in most of the cau-
dals, the anterior of the latter and the lumbars of deeper vertical than trans-
verse diameter throughout. The articular surfaces were moderately shallow
biconcave in all, most strongly in the subproximal caudals. The neural arches
attached by permanent suture, and inferior surfaces for articulation of chev-
ron bones. None of the caudals offer indication of elevated neural spines ;
they appear to have been on the majority low, and of considerable longi-
tudinal extent. Articular surfaces for chevron bones cease near the middle
of series, so that we can safely infer that the tail was cylindrical. Zyga-
pophyses turned upward, not outward.

The disproportion between the fore and hind limbs of the Iguanodon,
together with the compressed form of the tail suggested to Prof. Owen an
aquatic habit, a relation of proportions of limbs to habit seen in the tailless
Batrachia. The discovery of the massive short-toed foot of the Iguanodon
subsequently, has lent little countenance to the supposition of its entire adap-
tation to aquatic life. Dr. Leidy has regarded this disproportion in the cage
of the Hadrosaurus as an index of a habit like that of the Kangaroos (Macro-
pus, etc.), and that that monster rested in an oblique position on the hind
limbs and tail, and reached upwards with its muzzle and short fore limbs to
the foliage on which it fed.

[Aug.

NATURAL SCIENCES OF PHILADELPHIA. 279

That such a habit characterized the Laelaps is very probable ; the tail
was nearly cylindric, and from the extent of the condyles of the femur, the
hind limb must have been considerably flexed. The small size of the fore
limbs must have rendered them far less efficient as weapons than the hind
feet, in an attack on such a creature as Hadrosaurus ; hence perhaps the
latter were preferred in inflicting fatal wounds. The exceedingly eagle-like
character of the digits and claws and ornithic type of sacrum elucidated by
Prof. Owen, suggest a resemblance in the use of the limb.

The bulk of the species, as compared with that of Hadrosaurus, illustrates
again the law observed in the relation between Felis and Bos, Thylacoleo
and the herbivorous implacentals of its time, and the other raptorial and
herbivorous Dinosauria, which might probably be reduced to exact terms.

The remains indicate an animal of near 18 feet in length, which could pro-
bably raise itself to a height of six feet at the rump

To recapitulate ; the genus Laelaps belongs to the family Dinodontidse,
which is characterized by its contractile raptorial claws and slender digits.
aDd compressed sabre-shaped teeth. It differs from Megalosaurus in its femur
and from Dinodon in that teeth of the latter have two posterior serrate
edges separated by a posterior plane. From supposed Dinosaurian genera of
doubtful affinity, it differs e.g. from Regnosaurus Mant. in the totally different
humerus, and from Pelorosaurus and Streptospondylus in the vertebrae. Ce-
tiosaurus and Cimoliasaurus were perhaps mutilate like the Cetaceans, accord-
ing to Owen and Leidy.

In connection with the same fossil were found Cucullaea and Baculites sp.,
and not more than twenty feet off a femur of Hadrosaurus ; also portions of
Mosasaurus, Hyposaurus, Thoracosaurus and Bottosaurus, occurred in the
neighborhood.

The phalanges figured by Prof. Leidy (Smithsonian Contributions xii.)
Cretaceous Reptiles, Tab. 17, fig. 8 — 11, probably belong to the present species.
•They are included under the head of animals allied to Hadrosaurus.

In conclusion, the thanks of scientific men are due to Superintendent Voor-
hees for the interest and care evinced in the preservation of these valuable
specimens. Were all persons engaged in digging marl equally interested
in the preservation of bones which come under their notice, we might have
been far nearer an elucidation of this, one of the most extraordinary faunaj
which have been placed upon our planet.

The study of the Vespertilionidae of Tropical America has never been un-
dertaken by any one having large collections at his command. With others,
I have hitherto refrained from entering a field where such facilities, and an
acquaintance with type specimens, appeared to be necessary aids to produce

results of value. In these particulars I am now no better prepared than at
any other time ; since but comparatively few specimens have reached me from
its localities, and all its types are to be seen only in European museums. But
having been compelled while studying the fauna of California to institute
comparisons between some of its members and those of the Mexican provin-
ces, to determine questions of distribution, I some time ago drew up a few
descriptions of forms, which I now think are new. These, together with
notes upon two bats from Aspinwall and Maracaibo, I propose to submit un-
der provisional names. Should any or all of them prove to be old species,
their descriptions can, without confusion, be appended to the original meagre
diagnoses, and may thus add to what little we know of these obscure animals.

This last group includes those given in my monograph as varieties of V.
nitidus, where I proposed that the name V. oregonensis, which was attached to
one of the specimens, should be retained, in the event of their proving to be
distinct. Now that it appears probable that there is a group of closely allied
species of Vespertilionida3 inhabiting the southwestern portions of the United
States and Mexico, of which V. nitidus is a member, I have concluded to place
the so-called V. oregonensis under one of this group, V. obscurus, and give, pro-
visionally, new names to the others. " V. oregonemis" bears no locality. As
regards the distinctions between the above specimens and V. nitidus, it will
be seen that the prevailing deep-plumbeous basal half of the fur above, with
its%rich chesnut, olive brown, or, in some specimens from New Mexico, a
sandy-chesnut tip, and the lighter shades of the same colors to the fur be-
neath, sufficiently serve. The superior border of anterior nares is semicircular ;
the 2d premolar of upper jaw wedged in between 1st and 3d to a degree pre-
venting it from being visible in profile fror% buccal side.

A revised description of V. yumanensis is also given, to correct some errors
in the original notice. The representation of the tail and interfemoral mem-

of this bat, recorded in the Memoir, are unavailable for comparison. They
were mislaid during the fire at the Smithsonian Institution in January, 1865,

This genus appears to connect the Noctilionidae with the present family :
with the former through Nyctinomus, with the latter through Nycticejus. The
circular nostrils, sub-truncate snout, the detail of inferior incisors, the angle
of lower jaw — to Noctilionid?e ; the tapering face, marked median groove, taper-
ing tragus and pointed ear, number and general arrangement of teeth, extent
of hard palate, length of tail and attachment of wing membranes, — to Ves-
pertilionidae.*

It reminds one of Nycticejus and Lasiurus in the slightly tumid face (this is
more marked in B,. tumida) and the dentition ; while the shape and relative
length of the auricle and tragus, and the decurvation of nasal bones, recall
Vespertilio.

* The value of the presence of one or more phalanges to the index finger, in the classification ef
this group, is not yet determined ; so the fact that this finger in Rhngeessa is made up of two pha-
langes has not been made a fe iture of the diagnosis. My attention has been recently directed to
this subject by remarks made by Prof. Peters (Monatsbericht. der Kbnig. Acad, der Wissenscbaft,
Berlin, Oct., 18(55), in his paper on the true position of Anlrozous,— who, by the presence of two
phalanges to the index fiuger of Antrozous, would remove it from the position I assigned it—the
Vespertilionidas— to the Megadermatidse: placing it in proximity with Nyctophilia. Butso far as I
have observed, the distal end of the first phalanx is always abrupt ; the interval between it and the
com our of second finger is membranous in Nyctinomus. but partially ossified, forming thus a second
phalanx in Lasiurus, Anlrozous, Vespertilio, Scotopliilvs, and Nycticejus. lam not acquainted with
Nyctophilus, but in Mtgaderma lyra the second joint is relatively no larger than in Lasiurus or
Scotophilus. while it is more marked than it is in Anlrozous. From reading Mr. Tome's description
of Nyctophilus (Proc. Zool^Joc, 1858, 25), I would.with Prof. Peters, approximate it to Antrozous, but
would agree with Mr. Tomes in considering Nyctophilus and its congeners as members of Vesper-
tilionidffl. A»second phalanx exists in my new genus, while no such phalanx is seen in Nyctino-
vi us. 80 it w.ull appear, in absence of the observation that the um-phalangeal index finger is not
common to Noctiliouidae, that Shogeessa, is nearer Nycticejus than Nyctinomus.

In determining the species of Scotophilus of North America, I had been
influenced bv the authority of Major John Le Conte (Mon. on N. A. Bats) to
consider 5. carolinensis as distinct from S. fuscus, although suggesting at the
time that they might prove to be identical. I now venture to consider them
such, and make the former a synonym to the latter. This has not been done
hastily. It is not to be presumed that all the specimens of S. fuscus found in
this country are identical in every particular. They arrange themselves in
groups, of just sufficient definition to mislead the observer. But it is found,
upon careful comparison, that so vaguely are the boundaries of these groups
determined, that it is impossible to assign them precise limits. Among the
characters selected for this purpose, successively embraced and relinquished
(apart from the coloration of fur elsewhere noticed), are the infra-orbital fora-
men, whether it be well defined in front or open ; the zygomatic arch, whether
straight on inferior border and forming a right angle with the tuberosity of
superior maxilla, or curved on inferior border, and forming an obtuse angle ;
the inner side of orbital space, whether flat or convex ; the glenoid cavity,
whether transversely elliptical or lozenge-shaped ; the tragus, whether in-
curved at tip or straight ; the outer border of ear, whether emarginated or
nearly entire ; the nostrils, whether palmate or reniform ; and the proportion-
ate size of the foot and thumb. But it does not follow after all that I am
correct in this conclusion. A more acute observer than myself may yet divide
S. fuscus into sevt ral species.*

The extent of the ex-liniital distribution of this species is not yet deter-
mined. M. Gervais thinks it probable— and the extended study he has given
this group renders his opinion valuable — that S. dutertfeus is identical with
"carolinensis," and that both S. innoxius and S. furinalis may be found in
North America. I have seen several specimens of S. fuscus from Mexico which
present no differences from those met with in the United States.

Another specimen, however, from Mirador, Mexico, has peculiar coloration,
and may receive the following description :

S. MIRADORENSIS, n. S.

Head and auricle much as in S. fuscus. Inner border auricle inclined, ob-
liquely rounded; inner edge free ; anterior border nearly covering eye; tip
rounded, turned very slightly outward ; outer border scarcely if at all scooped
out ; basal third moderately re volute. External based lobe oblong and crescent! e,
not markedly turned inwards ; as long as interval between it and angle of mouth.
Tragus erect, nearly half as high as ear, straight on inner border, tip not in-
curved ; outer border divergent, slightly convex ; basal lobe obtusely rectan-
gular, turned somewhat forward. Nostrils snb-reniform ; posterior angle well
defined; space between nostrils as usual, naked, concave. Mental space illy
defined. The supra-orbital and gular warts as usual. Membranes light brown,
attached to base of toes ; phalangeal callosity of thumb marked ; tubercle
present on tibial side of foot ; a larger one on fibular side for membranous cal-
caneum. Joints of tail nine^; terminal and half penultimate free. Inter femoral

A small collection of bats made by Dr. E. Coues, U.S.A., in 1864 and 1865,
was found to be comprised as follows :

7802. V. subulatus, Fort Whipple. Smithsonian Institution. Dry.

7803 " " " " " "

The only peculiarity in these specimens is a more extensive distribution of
the fur over the dorsal surface of the interfemoral membrane than is seen in
the more eastern specimens.

The fourth specimen was an imperfect skin. The proportions of the face
distorted, the wings broken, and the vertebra of the tail removed. Enough
remained, however, to detect marked differences between it and the others,
warranting, it is thought, a distinctive name.

V. macropus, n. s. prov.

Above, fur long, silky, basal three-fourths black, apical fourth uniform light
russet brown ; a small clump at base of inter-femoral membrane. Beneath,
same proportions as above, being at base black, at tip greyish-white, pure
white at pubis ; fur extends laterally on membrane midway to elbow. Wing
membrane attached midway between base of outer toe and ancle joint. In other re-
spects it closely resembles V. subulatus.

Mr. Thomas Meehao remarked :

I present to the Academy specimens of Pinus pungens, Michaux, gathered by
me on the east side of the Schuylkill River, in the Blue Mountain Ridge, near
Hamburg, in Berks County, about 75 miles from Philadelphia by the Reading
Railroad.

The greater part of the Pine here is of Pinus mops', with a few of P. rigida.
The P. pungent is scattered here and there amongst them. Further up towards
Port Clinton I saw it in comparatively large quantity, and on the opposite or
west side of the River, so far as I could judge by the appearance of the wood,
it seemed very abundant.

The discovery east of the Susquehanna is interesting from its formerly sup-
posed limited location on Table Mountain, North Carolina, by Michaux. Mr.
Loudon subsequently noticed its discovery in the Blue Ridge, in Virginia, and
more recently Prof. Porter, as recorded in the Proceedings of this Institution,
discovered it sparingly in the Alleghanies, near Huntingdon.

A very old collecter of plants, whom I accidentally met some few years ago at
Allentown, assured me that he had seen specimens .many years past in the
Blue Mountains, near there, but I supposed at that time he was probably mis-
taken. Its discovery now in the same ridge, leads to the probability that it is
by no means a local species, but may most likely be found scattered along the
mountain slopes from North Carolina to the Delaware.

In favorable situations it would probably become a larger tree than Pinus
inops. I measured one standing by the road side that was 5 feet in circumfe-
rence, about four feet from the ground. The tree was apparently 50 feet high.

Dr. Leidy exhibited specimens of a large Coccus on the Black Oak,
Quercus tiuctoria.

Mr. Cassiu remarked that the Crotophaga a?ii, from *Edenton, N.

tween the bay shore and the light-house of Ope Henlopen. Tbey had provided
themselves with ample means to examine the extent of the shell heaps, and
had been surprised to find that they were all quite superficial, from a few
inches to less than a foot in depth. In a number of places they appeared to
form hillocks, but they were only accumulations around the former sites of
trees, as indicated by the traces of stumps and roots.

They visited 'similar accumulations on the shore south of the Cape, and were
told that they were found in many positions down the coast.

All of those which were examined contained fragments of pottery, chips of
jasper, and stone arrow-heads. A few copper rings were also found, and in
one heap Mr. Canby found several English coins.

Dr. Leidy thought the shell-heaps were of no great age, and were probably
coteruporury with the discovery of the country by Europeans.

October 30th.

Mr. Vaux, Vice-President, in the Chair.

Twenty six members present.

Drs. William Mayburry, and W. C. Dixon were elected members.

Dr. Hajrden, having just returned from a tour of exploration to the " Mau-
vaiscs Terres," or " Bad Lands " of White River, made some remarks in
regard to a side trip to the celebrated Pipestone quarry of North-eastern Da-
kota. He spoke of the locality as very inconspicuous, and that it would have
hardly attracted attention had the existence of this Pipestone bed not been
known to exist there. Not a tree is to be seen in the region round about, only
a few small bushes growing among the rocks. There is an escarpment, or
nearly vertical wall, extending across the valley of Pipestone creek nearly a
quarter of a mile either end of this wall, gradually passing from view beneath
the prairie. The entire thickness of the rocks is about 50 feet. The Pipe-
stone layer is about 11 inches in thickness; about 2|- inches is homogenous
and compact enough to be used by the Indians for the manufacture of Pipes.
The remainder is of various colors and texture, from a deep red to a cream, and
oftentimes mottled. The rock is soft, slaty, fragile, and underneath the Pipe-
stone is a bed of close-grained grey quartzite ; above there is about 6 feet of
the same rock, which must be removed with great labor before the precious
material can be secured. Still higher are 40 or 50 feet of reddish and varie-
gated quartzites, which, like the pipestone itself, are colored with peroxide of
iron. »

It is difficult to come to any positive conclusion as to the age of these rocks,
from the fact that no well defined organic remains could be found. It is the
opinion of the eminent geologist, Prof. Hall, that they belong to the Iluronian
series, and, from his large experience among those rocks, and the fact also that
he describes similar quartzites at a point within 60 or 70 miles of the quarry,
entitles his opinion to great weight. Rocks of the same age occur at Sioux
Falls, and upon the smooth surfaces may be seen, in great numbers, the out-
lines of what appear to be bivalve shells, but so close grained is the quartzose
matrix that no well-defined shell could be broken from it. If these rocks are
really charged with fossils, we are led to look higher in the geological scale for
the true age of the Pipestone bed.

Dr. H. remarked, in regard to the time of the opening of this quarry by the
Indians, he does not think they had any knowledge of the rock far back in the
past. No trace of stone implements were discovered in the vicinity, and he
could not ascertain that any had ever been found. Mr. Vaux, Vice-President
of the Academy, has examined large collections of stone implements and orna-

1866]

ments from ancient Indian mounds, without ever seeing any made of the pipe-
stone. Acting on this suggestion, Dr. H. examined such works as were within
his reach, and he could not ascertain that the numerous and careful explora-
tions of the mounds in the Mississippi Valley have as yet revealed any ornaments
made from this rock. The Indians must therefore have discovered the quarry
since the stone age.

Dr. H. exhibited a number of ornaments manufactured from the Pipestone
by the North-west Fur Company. They consist of pipes of various patterns
and sizes, cups, candlesticks, etc. They are turned in a lathe. Within a year
or two this company have made nearly two thousand pipes, which they send
up to the Upper Missouri Indians, near the foot of the Rocky Mountains, and
trade them for a robe a-piece. Hereafter some doubt will be thrown upon the
genuineness of these Indian pipes.

On favorable report of the Committee the following were ordered to
be published.

On the Period and Ratio of the Annual Increase in the Circumference of Trees.

BY THOMAS MEEHAN.

The following experiments were instituted in order to ascertain whether the
production of wood in trees was more rapid during some portions of the grow-
ing .season than others, and at what periods growth commenced and ceased in
the species of tree chosen.

The Carolina poplar (Populus monilifera Ait.) was selected on account of
its rapid growth, enabling me to easily note the increase of circumference
each seven days.

The following table shows the result. For the sake of system, the same day
in the week was chosen. In order to tabulate the figures, the same date is
used for the three years ; but as the same day fell on different dates, there is a
difference of three days in each date. For instance, May 17 in 1863 is May 18
in 1862 and May 20 in 1866 — the three years during which the measurements
were taken.

From these figures it appears the tree increased in growth only during the
three months between middle of May and middle of August, and that the
ratio of growth is much greater during the month between middle of June
and middle of Jul}' than during the month preceding and the succeeding
month.

Third Coatribution to the History of the BAL.2SNIDJE and DELPHINID.E.

BY EDWARD D. COPE.

DELPHINIDJB.

Orca destructor mihi sp. nov.

Among the species of this carnivorous genus of Cetaceans, the present ex-
hibits the most compact and powerful stiucture, and it, no doubt, is fully
equal to any of them in its sanguinary habits. The breadth of the pre-
maxilliary bones allies it to the species c rassidens and rneridionalis,
which have b»en called Pseudorca by some.

It diffeis from the latter species in the greater breadth and obtuseness of
the muzzle of its cranium and mandible— all we possess of it — and in the
smaller number of teeth ; the premaxillary bones are relatively narrower
throughout the greater part of their length. •

The width of the muzzle at the lateral maxillary notch is a trifle less than
three-fourths the length from that point to the end of the muzzle ; the width
at the fifth tooth is a little greater, and quite'three-fourths that distance. The
prenarial triangle is smooth, concave on each side the medium fissure, and
extends to opposite the penultimate tooth. Teeth ?, the posterior tooth

being the last of the maxillaries, instead of the mandibulars, as in rneridi-
onalis. The teeth occupy closely the intervals of the opposing series ; those
of the mandible are directed well outwards anteriorly. The intermaxillaries
form an elevated ridge exteriorly opposite the notch ; opposite the fifth tooth
above each is less than double the width of maxillary exposed exterior to it.
Behind the last tooth the margin of the maxillary is flared upwards in a
steep arch ; from opposite malar process to posterior tooth equals from pos-
terior margin of latter lo same of antepenultimate tooth. The mandibles are
much depressed distally, and the symphysis equals one-third the length of
the muzzle fiom the notch ; the chin projects beyond the broad extremity of
the premaxillaries. Measurements : —

differ from the B. angustat a. Examination of a specimen received by the
Academy from Prof. BrunT't, of the Lavalle University, Quebec, shows the
postero-inferior process of the atlas to be present, Dr. Wyman's figure, pre-
viously cited by me, being erroneous in this respect.*

Puoc^na brachycium, Cope, Proc. A. N. Sci., Phila., 1865, 279.

The specimen supposed by me to be the Ph. communis, with which the
present species was compared, belongs to the Ph. vome ri n a* Gill, of the Cali-
fornian waters. Having since received from the Smithsonian Institution two
crania of the Ph com m u n i s, from the Nortli Atlantic, comparison shows a
greater resemblance to the Ph. brachycium. The differences are, the
maxillaries in communis are decurved, as in v o m e r i n a, and more than
in brachycium; in communis the vomer appears more posteriorly on
the palate, being less than Us own length in advance of tlie line of the
posterior teeth ; in brachycium this distance is nearly double the length
of the visible portion. The projecting portion of the pterygoids is equal to the
portion in advance of the posterior margin of the maxillaries, while in the
P. brachycium it is much less. The muzzle in advance of the posterior
extremity of the vomer is barely contaiued 2j times in the length to the ex-
tremity of the pterygoids, while it is one third that distance in the commu-
nis. In other respects the crania, including the teeth, are nearly similar;
and it must be admitted that the full establishment of our species must de-
pend on further investigations.

gonys short; teeth very short, obtuse, numerous.

It will be a matter of importance in the completion of the characters of
this genus, to ascertain the presence of a dorsal fin. Supposing it to possess
one, it remains intermediate between Delphinus sect. Lagenorhynchus, Gray,
and Phocania, differing only from the latter in the cylindric form of the
teeth. Like the Phocsenre, the only species has the posterior extremities of
the intermaxillaries much elevated and smaller. Supposing it to lack the
dorsal fin, it will differ from Neomeris in the form of the teeth, from beluga
in the number of the teeth, and from Delphinapterus in the horizontal or-
bital plates and prenareal triangle of the latter.

basal one-fourth, one third breadth of combined premaxillaries, not recurved
on the margin. Antero-exteiior ridge of nasals prominent, enclosing two pita
behind margin of vomer ; median portion of f rentals separating nasals well from
supraocoipital, and the same from each other by an anterior process ; with an
anterior process of supraoccipital forming a prominent knoh. Supraoccipital
crest remarkahly strong and directed nearly horizontally forwards. Pterygoids
in contact on the median line, posterior margins widely divergent ; inferior
angles separated, much rounded, median depression considerable. Common
suture of palatines considerable, nearly equal gonys. Maxillaries closely in
contact on the palate, not exhibiting vomer or premaxillaiies, except a little
of the latter on the distal inch. Corouoid process of mandible everted : ramus
on distal half thickened internally, so that the dental series converge far less
on the posterior half its length than on the anterior. Occiput transverse, little
convexity between the posterior ridges of the temporal fossae. Latter large,
subrhomboid in outline. No portion of maxillaries visible between prenareal
swellings ; these elevations descend gradually anteriorly and are steep later-
ally, not grooved. Longest (right) prolongation of premaxillary not attaining
nasal hone.

The remaining and more prominent features of this species are apparent from
the following measurements : —

The shelving form of the supraorbital plates of this species suggests a re-
lationship to the Delphinus (Tursio) eu tropia, Gray, but it is evident that
the S. amblodon differs entirely from any species of Delphinus hitherto
known.

The habitat of this species is uncertain. It was taken off the ship Vincennes,
of the U. S. Exploring Expedition. On inquiry of Dr. Charles Pickering,
naturalist on board of that vessel, he has no record or recollection of the cap-
ture of such a species ; it was therefore probably procured while he was absent
from the ship from Cape Horn to Lima, or afterwards during his stay on laud
in Australia and New Zealand.

Delphinus longidens.

Of the type of D. (Tursio) obscurus Gray, but with considerably longer
muzzle and much longer prenareal triangle, the rugose surface of which ex-
tends to the end of the basal third of the length of the muzzle. Muzzle from
notch just twice the length of cranial chamber, shorter than mandible, flat above
on the basal two-thirds, the premaxillaiies continuous with maxillaries, not
bounding the triangle in front by a ridge. Sides of muzzle quite steep near
tip. Prenareal portion of triangle full plane. Premaxillaiies not visible on
palatine surface till near tip; pterygoids not in contact, prominent ridge. Teeth
slender, acute, spreading, four and an interspace iu an inch, so, anteriorly

not separated by alveolar partitions ; occiput flat, rounded in profile ; nasal
bones subtransverse, very near the moderate supraoccipital crest.

From the above it will be seen that the nearest ally of this species is the
Delphinus (Lagenorhynchus} clanculus Gray, in which the muzzle is
considerably shorter and the cranium relatively longer and wider; that is,
length of cranium proper equal in the latter to the length of the muzz'e, and
breadth at orbits a little greater than either. Its form renders a distinction
between Lagenorhynchus and Delphinus improbable, on present bases.
Habitat unknown. Museum Smithsonian, No. 388(5.

DELrHINCS PLAGIODON, Sp. 110V.

A robust species of the subgroup Tursio, (Gray), with a strongly depressed
triangle extending but little in advance of the posterior tooth. It is in many
points allied to the D. d o r i s, but differs in the muzzle being compressed
rather than depressed, especially at the tip, the teeth fitting very closely and
compressed transversely to the jaw, scarce four in an inch; aiid from the
specimen of the Museum Salem, in having the mandible heavy and much
prolonged at the symphysis. The form is an approximation to Steno, but the
symphysis is short, nevertheless not more so than in St. tucuxi Gray.
Until other characters are educed it will not be possible to distinguish Steno,
Tursio, Delphinus and Lagenorhynchus as more than one genus. In this
view I support the already expressed opinion of Lilljeborg.

Maxillaries much decurved, their elevation above the alveoli scarcely greater
than that of the premaxillaries above themselves. The latter form a very
strong rounded ridge, straight as far as visible in profile. Width at notch
two and two-third times in length. Prenareal part of triangle moderately con-
cave medially, with the term nal portion rugose. Supraorbital plates of
maxillary externally thickened ; in front of notch distinctly recurved. Ptery-
goids in contact, exteriork plane, inferior angle sharp, included depression
angulate. Vomer well displayed at middle of palatal face, not in contact with
maxillaries ; premaxillaries narrowly visible on the anterior half. Teeth 3<t

This species resembles closely the figure of the D. doris given by Dr.
Gray in Zool. of Erebus and Terror, but does not at all agree with his descrip-
tion published in the Catalogue Cetaceans Brit. Mus., 1865, which applies
closely t» the specimen described by me, Proc. Academy, 1865. As the crania
which have fallen under my observation are those of undoubtedly distinct
species, I have been at a loss which to regard as the true D. doris. I think
it would probably be more acceptable to the describer of the latter to regard

[Oct.

NATURAL SCIENCES OF PHILADELPHIA. 297

the description written by himself as the more infallible test, than the figure
drawn by another, and therefore more liable to error. A figure of that which
coincides exactly with Dr. Gray's description will shortly be published.

It may be mentioned that the teeth of Delphinus erebennus, stated by
me to be truncate like those of the D. tu r s i o, on the authority of Dr. S. J.
Howell, are found on examination to have an exceedingly oblique truncation
behind, extending from the alveolar line to the apex.

An examination of the skeleton of the cetacean described by Prof. Talia-
ferro, Proc. Acad. 1866, page 8, and now deposited in the museum of the
Academy by Dr. P. A. Taliaferro, has shown it to be the above named
species, which is therefore to be added to the United States Fauna.

Length from end of muzzle over convexity of back, forty-six feet nine
inches ; girth about nineteen feet: length from end of muzzle to axilla, (ex-
ternal measurement, ) fifteen feet ; breadth of head across inferior margin of
jaws, eight feet. Length of the pectoral extremity four feet, greatest breadth
fifteen inches; they were situated close behind the angle of the mouth. There
were 3(;0 lamina? of black baleen, extending on either side of the mouth about
six feet along the jaw, the longest about eighteen to twenty inches. The head
was acute. The folds of the throat many and capacious. The dorsal fin was
represented by a conical mass covered by horny integument, without any
membranous appendage, situated well posteriorly. The body near the tail
very slender. The flukes suddenly expand to a breadth often feet. The ver-
tebral line from the dorsal fin to the flukes, with six or eight knobs or humps.

The supraoccipital overarches on each side, a lateral longitudinal concavity,

long, while the base of each ceratohyal is 5*5 inches across; body most pro-
longed posteriorly, where it is narrowed, truncate, and with a deep longitudi-
nal fissure.

The scapula is, as described for the species, like that of a Beluga, of con-
siderable longitudinal extent, and furnished with long coracoid and acromion.

Of the anterior extremity, the humerus is less than half the length of the
radius, thirteen inches long, with the articular surfaces for ulna and radius
nearly equal.

There are some peculiarities of the present individual which render its
identification with the Sibbaldius laticeps not yet entirely established.
Rudolphi observes that the acromion is v£ry rudimental in his type, while in
ours it is like the coracoid, well developed. Lilljeborg and Gray, 1. c, state
the dorsal fin to be compressed and fulcate, while in the Mobjack specimen it
is rudimental and conic. The hvoid bone is precisely as figured by Rudolphi.
The dorsal fin resembles that of the S. boreal is Fisch. (gigas Van Beu.), but
the species differs markedly in the following points :

Dubar says the posterior dorsal median line is keeled ; according to Dr. Talia-
ferro this one has several humps. Dubar's figure of the first rib differs very
much from ours : former, end emarginate, its breadth 2§ the length ; the latter,
end entire, breadth 4£ the length. Our specimen is entirely adult at a length
of 43 feet (axial) ; Dubar's specimen had attained 102 feet. This difference
is important, as growth ceases with the coalescence of the epiphyses, as in
other mammals. Lastly, Dubar's type possessed an inferior lateral process
on the seventh cervical, wanting in ours. >

The following extract from the Richmond Enquirer of Eighth month 23d,
1858, furnished me by Prof. Taliaferro, gives a lively account of the capture
of this specimen :

"On Wednesday, the 4th inst., an unusual excitement was manifested
among the fishermen at the mouth of North and Ware Rivers, on Mobjack
Bay, and in a few moments scores of canoes might have been seen pulling up
stakes and anchors, and making for the shore in every direction. It was soon
reported that an immense fish, supposed to be a whale, of incredible dimen-
sions, was cutting all sorts of capers in the Bay : blowing like ever so many
bulls, spouting water, and amusing himself by making a great rumpus, to the
great terror and peril of some of the citizens of the commonwealth, who ' go
down to the sea ' in small canoes. But after the lapse of a few hours nothing
more was seen or heard of the monster, and the report of his visit scarcely
excited attention, even if it commanded credence.

"On the Monday morning following, however, an extraordinary noise on
the river (North J near Belle Ville. the residence of Warner T. Taliaferro,
Esq., attracted the attention of the family about daybreak, and on hastening
to the shore, they beheld the creature aground ou a bar near the landing.

" The gentlemen, determined to attempt his capture, instantly le.iped into
a boat, and sent off for gigs, (small harpoons use I by our fishermen for strik-
ing the bonito, ) pulled around him to reconnoitre whilst the weapons were
being procured.

[Oct.

NATURAL SCIENCES OP PHILADELPHIA. 299

" Whilst they were laying off, however, quietly reconnoitering the salient
and weak points of attack, nie asuring with their eyes the length and breadth
of their immense adversary, and impatiently awaiting the collection and
arrival of the materials of war, the tide, which unfortunately was flooding,
lifted him, just before the preparations for the attack could be completed,
from his perilous bed in the sand* and with a prodigious effort he threw him-
self off the bar, bounded into the channel, and in an instant was out of sight.

" Nothing more was seen of him, and it was feared he had made his way
out of the capes, and to the bergs and ice floes of more congenial latitudes,
after his uncomfortable experiences of shallow water. But on Wednesday
evening, the 11th hist., he was again descried making his way, like a small
propeller, straight up North River, rising every ten or fifteen minutes, throw-
ing graceful jets d'eau into the air more than thirty feet high, and sporting on
the surface of the water. When eff Burgh Westra, the residence of Dr. P. A.
Taliaferro, that gentleman, with his brother, Edwin Taliaferro, Esq., accompa-
nied by Mrs. , who, carried away by the excitement, insisted (under

threat of having her own boat manned) upon joining the expedition, and wit-
nessing the sport, as well as sharing the peril. Having hastily collected all
the fire-arms at baud, consisting of shot guns and five-shooters, and having
fastened a sword to a staff for a lance, they pushed off with a trusty crew of
negro oarsmen, in a launch of twenty feet in length, and rowed boldly for the
huge monster. He arose usually to breathe and spout water about every ten
or fifteen minutes, and then descended, reappearing at the expiration of that
time between a quarter and half a mile distant from the place of descent.

" Closely calculating the distance at which he would rise, and pulling in
the direction in which he disappeared, they succeeded in measuring so accu-
rately the time and space, that the third time he came to the surface after
they started, they found themselves within a few feet of him, as he lay with
his whole length expose 1 upou the water.

" To pour a heavy charge of buckshot into his flank was with Dr. T. the
work of an instant, when off the creature darted like lightning, pursued with
a hearty cheer by the boat's crew.

:' Again and again he rose, and again and again was the gallant boat with
her undaunted crew close beside him, pulling for their lives to head him, and
cut off his retreat from the river to the bay. For some moments, at one time,
he was seen swimming under the water, with his immense mouth, wide
enough to have taken in and crushed the frail boat, extended, and making
directly for her ; but a few quick and lusty back strokes of the oars put her
beyond peril, — and as he arose within ten feet of her quarter, a second dis-
charge of ball and buck drove him frantic upon a bar, and the blood- tinged
column of water which he spouted iuto the air told the story of a mortal
wound.

" Pulling the boat within a few feet of his body, far enough off to escape a
blow from his tail, Dr. T. courageously leaped overboard into five feet water,
and boldly attacked him with an impromptu lance, made of an old Toledo
blade which had done service in several wars. Though mortally wounded,
however, and attacked sword in hand, the whale would not yield himself van-
quished and a prisoner without another struggle, and, to the dismay of the
assailants and the crowds which had by this time collected on the beach, by
a convulsive and violent effort he floundered into deep water, and made a
straight run for the bay. But he was now too much exhausted to escape, and
the boat pulling fearlessly upon him, headed him within a few hundred yards,
and drove him again upon the shore, upou the estate, and near the residence
of Gen. Taliaferro, where cables and ropes were fastened to his tail, and he
was dragged to the shore by a force of over one hundred and fifty ne roes,
who had assembled to witness the sport, and despatched, after a most ex-
citing contest, from first to last, of over three hours.

" On dissection, the stomach was found to contain nothing but crabs.

On the REPTILIA and BATRACHIA of the Sonoran Province of the Nearctio

Begion,

BY EDW. D. COPE.

The material on which the present essay is based, is a collection made by
Dr. Elliott Coues during a sojourn of sixteen months in and ''travels over the
Territory of Arizona from east to west, chiefly near the parallel of 35°, and
along ihe valley of the Colorado from Fort Mojave to Fort Yuma." Notes
of observations made by Dr. Coues on the different species materially add
to their interest.

BATRACHIA.

Urodela.

Amblystoma ?nebulosum Hallowell, Journ. Acad. Nat. Sci. (?.) v. 252, iii.

In the Siredon stage differing from the S. gracil is Baird in its oblique
branchial arches with finer pectinations, and in coloration. On the anterior
side of he third arch, twenty pectinations or rakers may be counted ; in the
S. pisciformis (or mexicanus) there are but twelve. Color in life
" shining green above, silvery greenish-white below, more yellowish about
legs and gills; a few obsolete scattered black spots on head and b ick. Eyes
and branchial fimbrias black," (Coues' notes). 455 — 56 9 from Jacob's well ;
No. 491^ from a deep water tank in the rocks of the San Francisco moun-
tains.

Male about seven inches long ; branchiae well developed ; gular derm free
half-way to symphysis mandibuli. Twelve costal folds. Muzzle slightly
narrowed jaws equal. Lateral and dorsal peritonaeum black. The lungs
extend to opposite the inguinal region. Corpus adiposum extending on
testes to their anterior extremity. Testes undivided, broad, length equal
half that from axilla to anus ; efferent vessels numerous, not entering directly
the vas uro-spermaticus. The latter is very slender, lying along the outer
margin, but not in contact with, the narrow kidney; opposite the latter re-
currently convolute, anterior to it straight, and extending to opposite axilla
with decreasing diameter. It empties into the rectum near the cloaca. Cloaca
protected on each side by a large vertical compressed gland, which is fringed
on its inferior border, (which is received into the lip of the cloaca,) and also
on its superior margin, which lies next the caudal vertebr e. It is continu-
ous in front of anus ; behind the two edges are pressed together. Integument
of cloaca throVn into numerous appressed vertical plicae, as in other Sire-
dons.

Stomach straight, extending to the left groin, filled with larvae of Diptera
Nematocera. Intestines long, rectum large.

Female smaller, many of the ova black. Tn these animals the tarsal and
carpal bones are fully formed, but cartilaginous. The pterygoid and pala-
tine teeth in continuous series, the latter slightly separated medially, and
coin eniric with maxillary series. On this character, preserved in a stage
of an allied species without branchiir, I proposed the genus Camarataxis, the
validity of which can only be established when the development of all our
Amblystomas is known. It is a stage nearer the larval condition than the
transverse series of A. o p a c u m, while the /\-shaped series of A. 1 u r i-
d u m is intermediate.

Bufo frontosus sp. nov.

A species most allied to the B. americanus, but differing in the shorter
and more elevated cranium, longer and larger hind limbs, and more acumi-
nate parotoid glands.

The canthus rostrales not marked, the muzzle descending very steeply from
the anterior angles of the orbits, shorter than the elevated perpendicular
muzzle. Fiontal ridges higher than eyelids, rising steeply behind, termina-
ting in two short convergent tuberosities, divergent, with interior creuations
behind ; postocular ridge equally developed, sending a very small process to
the anterior acuminate extremity of the parotoids. Elevation of cranium at
parietal tubercle equal to length of same from the same point. Eye large ;
tympanum distinct, half eye; parotoid narrow, long, acuminate at both ends.
Elbow to anterior margin of orbit ; heel to end of muzzle. Skin everywhere
with numerous small tubercles; soles rough ; toes half webbed.

Brown above, with pale vertebral line, and three pairs of deep brown me-
dium sized spots, with paler centres. Sides and lips with small brown spots.
Femur and tibia with one indistinct brown cross-bar each. Below uniform
yellow.

Total length four inches, of which the head is 9 lines to postocular ridges ;
breadth between orbits 2-5 lines ; hind limb 5 inches; sacrum 1 inch across.
One specimen.

Bufo microscaphus sp. nov.

Head broader than long, obtuse, muzzle descending in full arc to labial
border from line of orbit; superciliary ridges well marked, but concealed by
the thick skin, plane, parallel; postorbital not prominent; vertical gutter
narrow. Eyes large, prominent, double tympanum. Parotoids broad, smooth.
Skin little roughened. Toes two-thirds webbed ; shovel very small, fre-
quently not black-edged, outer tubercle small, heel to end muzzle.

Above blackish, a black spot on each parotoid, and dark light centred bar
on femur and tibia ; a yellowish bar across front and palpebral, and spot on
nape ; muzzle dark.

Total length 1 in. 5-5 1. ; to postorbital ridge 7-5 1. ; fore limb 1 in. 9 1. ;
hind limb 3 in. 2 1. ; femur J included.

The oval, well separated parotoids and general appearance of this species
ally it to the B. s p e c i o s u s Girard, but in that animal the supraorbital
ridges are obsolete, and the metatarsal shovel is very much stronger. The
B. dorsalis Hallow. (B. woodhvusei Gird.) is also allied, but is in all pro-
portions and details more elongate, and has a stronger shovel and head
ridges ; it always has the dorsal band, which never exists in the microsca-
phus, and never the transverse face-band of the latter.

Phiynosoma douglassii Bell. Tapaya ornatissima Girard, Herp. U. S.
Expl. Ex. 1858, 396.
Abundant, and exhibiting much variety of coloration, some being uniform
brown above, some with dark cross-bars, light edged behind, some with d;irk
oval spots, and some with dark yellow-edged spots; others have the tempo-
ral spines and sides of the head bright red. The length of the tail varies
from one and three-fourths to two and three fifths times in the total.
From Fort Whipple, San Francisco Mountains, and the Colorado Chiquito
River. The two from the last locality are the only ones with oval brown
yellow -edged spots. Dr. Coues says of this species: "Very abundant at all
points from Santa Fe to Fort Whipple, chiefly in dry and sandy or rocky
situations. The males are usually smaller and more delicate in form than
the females. Those of the latter sex taken after the middle of July were al-
most invariably pregnant, and the young appeared in great numbers after the
first of August. When on sand or soft soil, the horned frogs watch their
chance, and when they think nobody is looking, they quickly and quietly
bury themselves quite out of sight. This is accomplished by a gradual, in-
sinuating, lateral and forward wriggling of their bodies: nose down, and
paws drawn to their sides. vVhen newly caught, some of the larger speci-
mens are a little inclined to be irascible and pugnacious ; and they bite, but
rather weakly. If a dog approaches, they stretch up on their legs, swell out
their bodies, open their mouths, and make a low hissing noise. This is about
all they do, however. They always become tame and quiet after a few min-
utes' handling. They eat readily, snapping at passing flies, and catching
them by protruding their viscid, fleshy tongues. When tickled with a straw
they lean the whole body towards the side touched, humping up their backs,
and setting their horns ; but this is the utmost they do on the defensive, tor-
ment them as you may."

Phrynosoma brevirostre Girard, Herp. U. S. Expl. Exped. 1858, 377.

One specimen from Bero Springs (No. 407). This species is very near the
P. douglassii, but has the muzzle and nostrils of the P. cornutum
type, that is, the latter on the front of the muzzle ; the tail is also very short,
being a little over one-third length of head and body ; above with a few
pairs of pale-edged brown spots. I am not prepared to depend on its perma-
nent distinction from the P. douglassii.

Crotaphytus collaris J&y, Holbrook, N. Amer. Herp. ii. 1842, 72, tab.

From Bero Springs and along the Colorado Chiquito River, where they are
abundant. Dr. Coues says of its habits: "Occurring on sand, logs, among
brush, etc. Throat very dilatable, os hyoides large and strong. Length 11
— 12 inches. Bites fiercely, and a little powerfully when caught. Common
all along the Colorado Chiquito River.

" In confinement, this species is just the opposite of the smaller lizards and
of the horned frogs. They retain to the last their fierceness and irascibility,
and their biting inclinations. My specimens were all perfectly untameable,
though petted for several days ; they all ultimately died, apparently of pure
rage and chagrin at being trapped. They bit fiercely at the finger, and
whipped good-sized dogs. They also bite indiscriminately a stick or anything
else presented to them ; and hold on so tenaciously that I have hung them
up for half an hour by their hold on a stick or string. They were ever on
the alert, watching every motion with cuuning and wrathful eyes. Every
now and then they would seem to lose their tempers completely, and tug
frantically at their ' lariettos,' leaping fiercely about in all directious. They
refused all food, and their lovely colors faded very perceptibly some time
before death."

at all times, silently and furtively hunting for flies. Although so familiar,
it is exceeding timorous and darts out of sight at the least movement or noise.

ground the eye can hardly follow it ; but receives merely a dim impression of

Asinea.

Contia i s o z o n a n. sp. nov.

Char. Two postoculars ; six rows of gular scales. Rostral rounded, slightly
produced backwards. Scuta 158 1, 52. Twenty black half rings, separated
by equal spaces of pinkish ground color.

Descr. Eye small, diameter twice in length of muzzle. Preorbital nar-
rower above, not extending above lower margin of superciliary ; loreal twice
as long as high. Prefrontals and internasals much broader than long; frontal
slightly angulate in front, longer than broad ; parietals rather elongate, sub-
truncate behind. Postorbitals subquadrate, temporals 1 — 2. Postgenials
minute. Superior labials seven, all higher than long, eye over third and
fourth. Scales in fifteen rows, all broader than long. Tail four and two-fifths
times in total length, which is 10-25 inches. Below immaculate; tail com-
pletely six-annulate.

Utah, from A. L Siler, indicates a variety. The body is longer than in the type,
and is crossed by twenty-five black bars, between these and on top of muzzle
Vermillion, below yellow. Scuta 167 I 52. Both specimens resemble the
Sonora semiannulata B.&G., but that species has two nasals, three
postoculars, the superior reaching the frontal ; frontal wider behind than
before, and only 149 gastrosteges.

Rhinochilus 1 e c o n t e i Bd. Gird., Catalogue 120.

with subquadrate black spots opposite the former and their intervals. Other-
wise as types.

Phimothyra h e x al e p i s n. sp. nov.

Resembles the P. grahamiae [Salvadora B. G ) but differs in having a
shorter tail, five and one-third times in length, instead of four times ; eye
resting on sixth supralabial on account of the presence of three narrow pre-
oculars ; two or three loreals — largest higher than long; nostril on suture
between nasals and internasals; dorsal stripe narrow — one and two half scales
and lateral brown band wide, four and a half to five scales, whose superior mar-
gius are ochriceous at base. Rostral plate well developed, higher than broad.
Nasals elongate, much depressed, anterior extending behind first labial; post-
oculars two ; two long narrow temporals. Width of occipitals nearly equal
common suture. Nine superior labials ; first pair inferior labials much dila-
ted medially, their common suture nearly equal that of pregeneials. Scales

Specimen with loreal minute on one side, wanting on the other. As tbe
practice of employing generic names which have not been explained by a di-

sity, I employ in this and other cases Baird and Girard's names in prefer-
ence to the prior ones of Fitzinger ; e. g. the above, in place of Lampropeltis,

Ophibolus p y r o m e 1 a n u s m. sp. nov.

Char. Scales in 23 longitudinal rows ; tail five and one-half times in total
length. Scuta 224, 1, 66. Fifty to fifty-eight black annuli on an ochraceous
white ground, on the body ; each anteriorly completely, posteriorly more or
less incompletely split by a Vermillion annulus ; all extending with irregu-
larities on the belly.

Descr. Head quite distinct from body, muzzle contracted. Frontal plate
broad, with prolonged apex ; parietals elongate, emarginate behind ; cephalic
shields otherwise asinpolyzonus, splendid us, etc. Postgeneials half
the Length of the pregeneials. Dorsal scales rather broad, outer series not
abruptly enlarged. In one specimen all the black annuli to the middle of
the tail are divided by the red, thus leaving the black as a margin to it ;
hence the number of these annuli is fewer; they are four scales wide behind
the middle of the bo'dy ; in another specimen only four anterior rings are
completely divided, those on the following third of the length being divided
by red on the sides ; the remaining annuli black, three scales wide ; white
annuli one and one-half scales ; anterior or nuchal red ; annulus widest, its
anterior black margin attaining parietals ; an ochraceous band from gular
region, not quite completed across parietals. Muzzle, prefrontal plates and
labial margin ochraceous, remainder of top and sides of head black. Total
length 30-5 inches. Nos. 731 — 760.

This species has a longer body than the known red-ringed species, and is
indeed most closely related to the 0. b o y 1 i i • it will always be distinguished
from the latter by the much more numerous annuli (twenty-eight in b o y 1 i i.)

from the Arizona form, as I pointed out in t^ynopsis of Crotali in Mitchell's Re-
searches, not having then seen specimens of the latter ; yet the two are pro-
bably varieties of but one species. They differ as follows :

between superciliaries ; ground color above bluish slate, no yellow band be-
tween eyebrows, on rostral, or margining labials in front. Spaces between
dorsal spots orange

smooth. Head short and very obtuse, the nostrils opening subvertically.
Superior labials higher than long, three rows of temporals smooth ; scales of
vertex small, keeled ; those more anterior, striate. Superciliaries broad oval,
striate. Canthus rostralis none. Inferior labials fifteen, the first and second
margining a plate which meets its fellow in front of the geneials, and is in
other species a continuation of the first. Gastrosteges 178, urosteges 24;
joints of rattle 9. The general tint of this species is a bright salmon red, the
scales of the inferior rows punctulate with brown. Other details of structure
and coloration are given in the description below.

The species is one of the most handsomely colored of the genus. Its affini-
ties are with the C. m i t c h e 1 1 i i m., but it exhibits an even higher degree
of subdivision of the head shields. Mus. Smithsonian, No. 6606.

I am now acquainted with eighteen well defined species of this genus,
while one or two named remain to be further investigated. They are dis-
tributed as follows :

Regio Neotropica 5

S. R. Brasiliana 2

S. R. Mexicana .' 4

Regio Nearctica 13

S. R. Sonoriana 10

S. R. Californiana 1

The intensity of distribution is then the Region of Lower California, Upper
Sonora and Arizona, which has seven peculiar species, and three which enter
from the neighboring districts.*

The only genus occurring at Cape St. Lucas which does not exist elsewhere
in the Regio Nearctica, is Ctenosaura, which is Mexican.

Prof. Baird has regarded (Proc. Acad. 1859, 300) the Sonoran and Lower
Californian provinces as identical, and has pointed out the slight affinity of
the latter to the Pacific district. It appears from the preceding that, in re-
spect to the reptiles, they constitute provinces nearly as distinct from each
other as the Sonoran is from the Central, a conclusion agreeing with that
attained by Dr. John L. LeConte from a study of the Coleoptera, (vid. Proc.
Acad. 1861, 335). That these, and the Pacific province, are more nearly re-
lated to each other than to the Eastern province, is sufficiently apparent on
general Herpetological and other grounds, as set forth in Prof. Baird's masterly
review of the distribution of North American Birds, Sillinian's Journ. Sci.
and Arts, 1866.

Dr. Giintber has indicated the Tropic of Cancer as the approximate division
line between the Nearctic and Neotropical Regions ; the writer (1. c. 1861,
306) has regarded tbis as the parallel of its eastern extremity, and placed the
western several degrees further north. More recently Prof. Baird (1. c.) has
indicated a less oblique division, raising the eastern extremity to the mouth
of the Rio Grande, and terminating it on the west at Guaymas. While he
characterizes the line as "arbitrary" for the birds, it is much less so for
terrestrial vertebrates ; in these the transition of faunse is striking and quite
abrupt.

Description o/Hyla curta Cope, supra.

Form stout, size small, breadth of jaws entering total length two and two-

Dr. Hayden made some remarks in regard to an extensive chalk deposit on
the Missouri river. He also exhibited to the Academy some fossils, fishes and
shells, which had been taken from these chalk deposits by Mr. Geo. A. Prop-
per, a resident of Yankton, the capital of Dakota Territory. This formation
has been known for many years, and represents No. 3, or Niobrara group of the
Cretaceous series of this region. It commences at a point on the Missouri
river not far from Blackbird hill, overlapping, on the high hills, Nos. 1 and 2
of the Cretaceous series. Near the mouth of the Vermilion River it begins to
occupy the country, to the exclusion of any other rocks, and passes beneath
the bed of the Missouri near the Great Bend. It is thus visible for nearly 400
miles along the river. The fossils which have thus far been taken from this
bed are not numerous in species. The Ostrea congesta, Conrad, is perhaps the
most abundant shell. It is found in many localities aggregated in vast masses,
reminding one much of the little raccoon oyster that is left by the receding of
the tide along the shores of the sea islands of South Carolina.

In< ceramus problematicus is abundant between Blackbird hill and mouth of
Big fr-ioux river. It is found in a grey, rather hard, chalk limestone, which
forms the base of the formation No. 3, and the rock is used much by the set-
tlers for building purposes and for burning into lime. I. p&eudomytiloide* and
/. cviculoides are found at different localities. This rock varies greatly in
eoler as well as texture, from a lead grey to milk white. It is oftener a deep
rust color, owing to the presence of the peroxide of iron. It resembles very
much our common chalk of commerce, and might be used for similar economi-
cal purposes. Although the organic remains thus far found in this formation
do not positively affirm it, yet there can be hardly a doubt that it is the Ame-
rica n representative of the white chalk beds of Europe. The fish remains are
mai y of them quite well preserved, and as they belong apparently to unde-
sci'bed species, they are placed in the collections of the Academy for future
study.

New Garden, 5th of Oth mo., 1866.
Isaac Lea.

Dear Friend, — As science is the accumulation of facts, and the legitimate
inductions derived from them, I offer no further apology for this intrusion.

Our Helieidse and other land shells generally pass the day in damp secluded
places, among grass, under logs and fallen leaves, and even buried beneath the
surface of the earth in dry weather, and are consequently difficult to find.
From these retreats they sally forth during the night, enlivened by the falling
dew — or still more by a shower of rain — in quest of food and pleasure. But
here they are screened from observation by the darkness of the night.

Knowing their habits, and having often found them under boards or other
dejected matter, it occurred to me several years ago to make this knowledge
available in collecting such shells. My success has been most gratifying to
myself — may it not prove equally so to others? "The plan which I adopted is
this : On a summer evening, after rain, I lay a wet board on the wet grass any-
where in my yard, lawn, or pasture, and on the following morning find the
shells adhering to the under surface. In this way I have at various times ob-
tained the following species in greater or less abundance : —

Succinea avara, Vallonia minuta,

Hyaliua indentata, Bulimus marginatus,

arborea, Leucocheila contracta,
Gastrodonta suppressa, corticaria,

Strobila labyrinthica, peutodon,

Anguispira alternata, Isthmia ovata,
Patula striatella, gouldii,

Helicodiscus lineata, milium,

Pseudohyalina minuscula, armifera.

Only a week ago, on removing a small log from my pasture, where it had lain
some months, I accidentally detected a few shells of Isthmia milium, hitherto un-
noticed in this vicinity. The next evening, after rain, I laid three boards, each
four feet long and six inches wide, upon the spot, and the next morning ob-
tained 250 1st. milium, 15 Leuc. pentodon, 3 Gast. suppressa, and 6 Pseud, minus-
cula.

The plan here suggested is susceptible of extensive application to the pur-
poses of the practical conchologist and travelling collector of shells, wherever
they may chance to pass the night ; especially so, as I have found by repeated
trials that a bucket of water thrown on the grass and covered with a board
affords all the conditions necessary for success about as well as a shower of
rain. No cumbrous apparatus is required to load the traveller; the means will
always be at hand wherever he may chance to lodge, and a few moments of
the evening and morning will suffice to set his traps and bag the game.

The record of a journey across this wide continent, so conducted, would

probably exhibit the ever-changing mycological fauna of the country in a very
ditferent light from what it now appears. New species would no doubt be dis-
covered, and the boundaries of the old ones more accurately determined.

Within the week I have obtained 366 /. milium in the locality mentioned,
and after considerable search have found only a single shell in the whole field,
more than four yards from the spot first designated ; a singular instance of
the extreme localization of a species which is quite numerous at that point.
Which is respectfully submitted by thy sincere friend,

E. Micheker.

Dr. Hayden reported the discovery of a Mastodon tooth in the Post-
pliocene drift near Fort Kearney, and another in the same formation
in the bluffs opposite St. Louis.

E. D. Cope pointed out the anomalous relations existing between the tibia
and fibula in certain of the Dinosauria, as illustrated by the genus Laelaps.
He remarked: The distal extremity of the tibia is transverse, and much com-
pressed, and does not exhibit any of the usual appearances of an articular sur-
face, neither the reptilian condyle, nor a cotyloid cavity sufficient for an astra-
galus of the size necessary for an animal of such bulk. A bone, presenting a
broad hour-glass-faced articular surface was discovered with the other remains,
and had puzzled the anatomists who had seen it. This piece exhibits, along its
whole posterior aspect, two faces, which form a reentrant angle for a fixed arti-
culation : this is found to have been applied to the extremity of the tibia, ex-
actly, and to have been fixed by strong articular ligaments. The medially con-
stricted condyle presenting forwards and a little downwards exhibits so little
analogy with the artragalus, as to suggest other interpretations, and, after a
careful examination, it seems evidently the distal extremity of the fibula.
This element furnishes a small articular surface at the knee, and fitting the
tibia by the concavity of its inner face, becomes greatly attenuated at its distal
third, where it is, in consequence of an obliquity of its direction, applied to the
anterior face of the former bone. It then spreads into a plate extending to the
inner margin of the tibia, while the solid shank is continued along the outer
margin, and both terminate in the massive condyle which embraces the whole
extremity of the tibia, like an epiphysis.

One other example only of this structure is known in the Vertebrata, of
which I only find mention in Cuvier, Ossemens Fossiles x., p. 204, tab. 249,
fig. 34-5. This author studied the distal extremity of a tibia with applied fibu-
lar condyle, from Honfleur, which he was not able to assign to any known spe-
cies or genus, but which he, with usual sagacity, includes in the chapter
devoted to Megalosaurus.

He however regarded the face of the tibia receiving the condyle-bearing
bone as the inner, instead of the anterior, stating that the tibia is laterally
instead of antero-posteriorly compressed, so anomalous is this structure among
vertebrates. He regarded the bone as the astragalus, and did not perceive any
connection between its ascending apophysis and a fibula, partly because a
fibula with distinct distal articulation was received with the same bones.

The fibular condyle possesses an articular facet on its exterior extremity,
(anterior, Cuvier), probably adapted to a corresponding face of a calcaneum.
Its plane is transverse and does not cover the whole extremity, the anterior
margin and a knob on the antero-superior part of the extremity projecting
beyond it. Exterior to the middle of the upper margin of this piece, and at the
internal base of the ascending apophysis, it is perforate, as is the cavity above
the condyles of the humerus in the higher apes, and may have received a simi-
lar coronoid process of an astragalus.

As compared with the species examined by Cuvier, this fibular condyle has
a less elevated form ; in Cuvier's specimen the ascending apophysis was flatter,
broader and directed toward the calcaneal facet instead of from it ; it lacked

fNov.

the submedian perforation. Its tibial face appears to have been rounded, not
angulate. The tibia presented an ascending ridge, to the face of which the
ascending apophysis was applied ; in the Laelaps aquil unguis there is no
ridge, the apophysis reposing in a slight concavity. This apophysis, like the
slender portion of the fibula, is composed of dense bone.

Cuvier describes at the same time a bone of which he says, " il ne serait pas
impossible que 1'os (fig. 39) fut la tete superieur du perone du pied que. je viens
de decrire." This piece has a shank compressed at right angles to the direction
of its head, a form so unlike the fibula? of known Dinosauria, including Mega-
losaurus and Laelaps, as to render its pertinence to the animal possessing the
forementioned tibia, to say the least, very doubtful.

The direction of the condyle indicates the articulation of the tarsal elements
to have been at a considerable angle with the shank of the leg, and that the
animal was entirely plantigrade, and was unable to extend the foot in line with
the lower leg. The animal's weight was no doubt shared by another tarsal
bone, besides the astragalus, owing to the anterior position of the former.

In most known Dinosauria the relations of tibia and fibula are similar to
those in the modern Lacertilia. It would appear then that this class existed
under two ordinal modifications ; the first, including Scelidosaurus Ow., Hylaeo-
saurus Mant., Iguanodon Mant., and Hadrosaurus Leidy, may be called the
Okthopoda ; the second including Laelaps Cope, and probably Megalosaurus
Buckl., may be termed the Goniopoda.

OPHIDIA.

Himantodes tenuissimus m. sp. nov.

Vertebral series of scales small, like the rest, altogether in seventeen
rows. Head broad, very obtuse, prenasals approaching each other ; loreal
subquadrate ; preorbitals 2 or 1, postorbitals narrow, two. Superior labials,

Body exceedingly slender and compressed. Gastrosteges 250, anal divided,
urosteges 157. Total length 2 feet 9 inches, tail 105 inches; length of head
5 lines.

Ashy white, with fifty transverse black light-edged spots on the body,
which approach closely on the median line ; on the tail 39 spots. Below,
belly minutely punetulated ; tail brown spotted.

The absence of the dorsal shields would indicate a wide separation of this
species from the type of the genus H. cenchoa L., but for the existence
of H. gemmistratus Cope, in which this series is much narrowed,
approaching the ordinary form of scale.

Xenosaurus grand is Gray, Cubina grandis Gray, Ann. Magaz. Nat. Hist,
xviii. 270. Xenosaurus fascia tus Peters, Monatsberichte Berlin Acad.

The genus Xenosaurus, first defined by the able Zoologist of the University
of Berlin, is of much interest. Prof. Peters referred it with doubt to tlie Helo-
dermidse, and in my system of the Sauria,* 1 have followed his suggestion, not
having had the opportunity of studying its skeleton. This having been
afforded by the specimens sent to the Smithsonian Institution by F. Sumichrast,
my conclusion regarding it is as follows : It is a Diplogloss in all points, pre-
senting the anomaly of very strong inferior frontal crests, which fail of under-
arching the olfactory lobes of the brain, approaching in this respect equally
the Gecconidse and Varanidse. The anterior limb of themesosternum is shorter
than in most of the Diploglossa. Parietal fontanelle distinct. The Xeno-
sauridse will stand in the system between the Gerrhonotidse and Heloderniidae
with the following diagnosis :

No premaxil/ary foramen, dentition strictly pleurodont, teeth with elongate
cylindrical shanks attached on inside of alveolar parapet ; head tubercularly
scaled, temporal fossa not over-roofed by dermossif cation ; mesosternum cr%ici~
form.

While the characters of the Helodermidse are :

No premaxillary foramen ; teeth with short dilated bases, obliquely anchylosed ;
head tubercularly scaled, temporal fossa overarched by dermoossification ; mesos-
ternum ivithout lateral limbs, longitudinal.

The supraorbital ossification in Xenosaurus is a triangular piece over the
anterior third of the orbit, attached to the prefrontal bone, not as in the other
Diploglossa, continued to the postfiontal. The ball of the eye is defined by
fourteen flexible sclerotic plates in front, whose contact is valvate except round
the pupil, where each one dilates and overlaps the next, forming an imbricate
circle.

Sceloporus heterurus sp nov.

Four and five rows of supraorbitals besides the internal and external margi-
nals. But little difference in size of dorsal, 'ateral and abdominal scales, the
first with strong keel and mucro, not serrate, in 45 transverse rows between
interscapular and sacral regions. Caudal scales much larger, with elevated
keels continued as ridges, in eighteen longitudinal rows 8 lines beyond vent.
Head scales smooth, the anterior frontal not divided ; occipitals distinct. Some
large marginal scales in front of auricular meatus. Femoral pores seventeen.

Color bright leek green with numerous delicate brown lines directed
obliquely forward towards the back and there turning backwards ; a narrow
line ascending from arm to interscapular region receives a longitudinal one
from orbit; a longitudinal line in front of thigh.

Total length 6 in.; from muzzle to vent 2 in. 6 1.

Ont he Agricultural Ant of Texas. (MYRMICA MOLEFACIENS.)
BY GIDEON LINCECIJM.

This is No. 2 of my catalogue — is inodorous, having no smell of formic acid.
It is a large reddish brown ant, dwells in the ground, is a farmer, lives in
communities, which are often very populous, and controlled by a perfect
government ; there are no idlers amongst them. They build paved cities, con-
struct roads, and sustain a large military force.

When one of the young queens, or mother ants, comes to maturity, and has
received the embraces of the male ant, who immediately dies, she goes out
alone, selects a location and goes rapidly to work excavating a hole in the
ground, digging and carrying out the dirt with her mouth. As soon as she
has progressed far enough for her wings to strike against the sides of the hole,
she deliberately cuts them off. She now, without further obstruction, con-
tinues to deepen the hole to the depth of 6 or T inches, when she widens the

bottom of it into a suitable cell for depositing her eggs and nurturing the
young. She continues to labor out-doors and in, until she has raised to ma-
turity'20 to 30 workers, when her labor ceases, and she remains in the cells,
supplying the eggs for coming millions, and her kingdom has commenced.
But very few of the thousands of mother ants that swarm out from the differ-
ent kingdoms two or three times a year succeed in establishing a city. How-
ever, when one does succeed in rearing a sufficient number of workers to carry
on the business, she entrusts the management of the national works to them,
and is seen no more outside.

The workers all seem to understand the duties assigned to them, and will
perform them or die in the effort.

The workers increase the concealment, which had been kept up by the
mot her ant during the period of her personal labors, of the passage, or gate-
way to their city, by dragging up and covering it with bits of stick, straw and
the hard black pellets of earth, which are thrown up by the earth worms, un-
til there is no way visible for them to enter ; and the little litter is so ingeni-
ously placed, that it has more the appearance of having been drifted together
by the wind than to have been the work of design.

In about a year and a half, when the numbers of the community have greatly
increased, and they feel able to sustain themselves among the surrounding
nations, they throw off their concealment, clear away the grass, herbage and
other litter to the distance of 3 or 4 feet around the entrance to their city,
construct a pavement, organize an efficient police, and, thus established,
proclaim themselves an independent city. The pavement, which is always
kept very clean, consists of a pretty hard crust about half an inch thick, and
is formed by selecting and laying such grits and particles of sand as will fit
closely over the entire surface. This is the case in sandy soil, where they can
procure coarse sand and grit for the purpose, but in the black prairie soil,
where there is no sand, they construct the pavement by levelling and smoothing
the surface and suffering it to bake in the sunshine, when it becomes very
hard and firm. That both forms of these pavements are the work of a well
planned design, there can be no doubt with the careful investigator. All the
communities of this species select their homes in the open sunshine, and con-
struct pavements. Their pavements are always circular and constructed pretty
much on the same plan. During the ten years drouth that prevailed here, and
which seemed very favorable to the increase of this species of ant, they suf-
fered their pavements to remain fiat, sometimes even basin-form. But the
■drouth could not continue always. The rain, which would be certain to drown
the ants should it come upon their flat and basin-form pavements, would re-
turn again some day, and they seemed to know when this much dreaded event
would occur. At least six months previous to the coming of the rain, they
.commenced, universally, building up mounds in the center of the. pavements.
'To these mounds in the prairie they brought the little pellets of earth, thrown
to the surface by the earth worms, and piled them up into a circular mound a
foot or more in height. In sandy soil it is constructed of coarse sand, and in
rocky situations they build it of gravel, and the pieces are so large, and the
.mound so high (18 inches to 2 feet, with a four feet base) that the beholder is
.overwhelmed with wonder. I know of one of these stone pyramids nearly 3
■ feet high and 5£ to G feet base, in which there are many little fragments of stone,
. some of them carried to the very top, any one of which would weigh more
than 25 ants. Internally the ant mound contains many neatly constructed
cells, the floors of which are horizontal ; and into these cells the eggs, young
ones, and their stores of grain are carried in time of rainy seasons.

The mound itself, and the surface of the ground around it, to the distance

of four or five feet, sometimes more, from the center, is kept very clean, like a

pavement. Everything that happens to be dropped upon the pavement is cut

,to pieces and carried away. The largest dropping from the cows will, in a

: short time, he removed. I have placed a large corn-stalk on the pavement,

[Nov.

and in the course of two or three days found it hollowed out to a mere shell ;
that too, in a short time, would be cut to pieces and carried off. Not a green
thing is suffered to grow on the pavement, with the exception of a single spe-
cies of grain-bearing grass, (Aristida stricta.) This the ant nurses and culti-
vates with great care ; having it in a circle around and two or three feet from the
center of the mound. It also clears away the weeds and other grasses all
around outside of the circular row of Aristida, to the distance of one or two
feet. The cultivated grass flourishes luxuriantly, producing a heavy crop of
small, white, flinty grains, which, under the microscope, have the appearance
of the rice of commerce. When it is ripe it is harvested by the workers, and
carried, chaff and all, into the granary cells, where it is divested of the chaff,
which is immediately taken out and thrown beyond the limits of the pave-
ment alwaj s to the lee side. The clean grain is carefully stored away in dry
cells. These cells are so constructed that water cannot reach them, except in
long wet spells, when the earth becomes thoroughly saturated, and dissolves the
cement with which the granary cells are made tight. This is a great calami-
ty, and if rain continues a few days it will drown out the entire com-
munity. In cases, however, where it has continued long enough only to
wet and swell their grain, as soon as a sunny day occurs they take it all out,
and spreading it in a clean place, after it has sunned a day or two, or is fully
dry, they take it in again, except the grains that are sprouted ; these they in-
variably leave out. I have seen at least a quart of sprouted seeds left out at
one place.

They also collect the grain from several other species of grass, as well as
seed from many kinds of herbaceous plants. They like almost any kind of
seeds — red pepper seeds seem to be a favorite with them.

In a barren rocky place in a wheat field, a few days after harvest, I saw quite
a number of wheat grains scattered over the pavement of an ant city, and the
laborers were still bringing it out. I found the wheat quite sound, but a little
swelled. In the evening of the same day I passed there again ; the wheat had
dried, and they were busily engaged carrying it in again.

The species of grass they so carefully cultivate is a biennial. They sow it
in time for the autumnal rains to bring it up. Accordingly, about the first of
November, if the fall has been seasonable, a beautiful green row of the ant rice,
about 4 inches wide, is seen springing up on the pavement, in a circle of 14 to
15 feet in circumference. In the vicinity of this circular row of grass they
do not permit a single spire of any other grass or weed to remain a day; leav-
ing the Aristida untouched until it is ripe, which occurs in June of the next
year they gather the seeds and carry them into the granaries as before stated.
There can be no doubt of the fact that this peculiar species of grass is in-
tentionally planted, and, in farmer-like manner, carefully divested of all other
grasses and weeds during the time of its growth, and that after it has matured,
and the grain stored away, they cut away the dry stubble and remove it from
the pavement, leaving it unencumbered until the ensuing autumn, when the
same species of grass, and in the same circle, appears again, receiving the
same agricultural care as did the previous crop ; and so on, year after year, as
I know to be the case on farms where there habitations are, during the sum-
mer season, protected from the depredations of cattle. Outside of the fields
they sow the grass seeds, but the cows crop it down two or three times, when,
finding that there is no chance to carry on their agricultural pursuits, they cut
it all away and re-establish the clean pavement. Our cattle did not often crop
the ant rice until their increased numbers have forced them to feed on all
kinds of grass. That, however, has turned out favorably to the ant interest.
For, while the prairies are being denuded of the stronger grasses, we have a
delicate little biennial barley (Hordium pusillum) that is filling all the naked
places. It rises from 3 to 6 inohes, producing fine grain for ant consumption.
It matures about the last days of April, and from that time all the agricultural
ants are seen packing it home daily through the summer. This species of ant

subsists entirely on vegetable seeds. I have sometimes seen them drag a cat-
terpillar or a crippled grasshopper into their hole, that had been thrown upon
the pavement, but I have never observed them carrying any such things home
that they had captured themselves. I do not think they eat much animal
food.

I have often seen them have prisoners, always of their own species. I could
not discover the nature of the offence that led to the arrestment ; still I have
no doubt as to the fact of its being so, and that the prisoner is very roughly
forced along contrary to its inclination. There is never more than a single
guard having charge of a prisoner, who by some means having obtained the
advantage, and attacking from behind, had succeeded in seizing it with the
mandibles over the smallest part of its back, and so long as it maintains this
grip, it is out of the reach of harm from the prisoner.

In some cases the prisoner quietly submits, and folding up its legs, forces
the captor to carry it along like a dead ant, as I thought it really was,
until I caused its captor to drop it ; when, to my surprise, it immediately
sprang to its feet, and, running wildly, succeeded in making its escape. It oc-
curs more frequently, however, that the prisoner does not give up so tarnely,
but continues to make every effort to rid itself of its detainer. I have many
times observed the prisoner manifesting all the indications of terror and great
reluctance at being so unceremoniously dragged along. It will lay hold of
and cling to everything that comes in reach, and by this means greatly
retard the progress of its captor. When at last they arrive on the city pave-
ment, half a dozen or more of the national guard, who are always on duty,
rush upon the prisoner, aiding the seemingly fatigued captor, who still main-
tains its potent grip upon the now almost helpless prisoner, seize it by the
arms, legs, everywhere, and in a very rough manner hurry it down into the
entrance to the city, and out of the reach of further observation.

The agricultural ant is very tenacious of life. I dissevered the head of one
at 4 P. It. on Sunday, and the head remained alive, retaining sufficient strength by
pressing with its antenna; against the slip of glass upon which it lay to move
itself and change its position, until 10 A. M. the next day.

It seems to be an established law amongst all species of ants, and particu-
larly with the species in question, that when any disaster occurs to their city,
the first thing to be done is to take care of the young, and, if possible, secure
their safety; and so, when by any accident one of their cities gets torn up, it
will be seen that they universally rush to the nursery apartment ; and every
one that can, takes up an egg, the pupa?, the young in any stage of advance-
ment, ami will save its life or lose its own. As far as I can understand and
read their actions, every one understands its duty, and will do it or lose its
life. I have observed the guards, when a sudden shower of rain would come
up, run to the entrance of the city, and there meeting with another party
coming up from below, would crowd themselves together in the hole in such
manner as to form a complete obstruction to the ingress of the water, and
there remain overwhelmed with the accumulating rain until it ceased. If the
shower continues over fifteen minutes, they are found to be still closely wedged
in the aperture and all dead ; and there they remain until the balance of the
pavement guards, who during the shower had climbed some weed or blade of
grass that grew near the border of the pavement, come down, and with some
difficulty succeed in taking them out. They are immediately taken to some
dry place on the pavement and exposed to the open air half an hour at least;
after which, if they do not revive, they are taken off from the pavement, some-
times to the distance of sixty yards, and left on the ground without further
care.

Long-continued rainy seasons, by deeply saturating the earth, will dissolve
the cement of their cells, flood them, and drown the ants out entirely. I have
allusion now only to the agricultural species of the genus. The first year after
my arrival in Texas, I noticed that there were a great many uninhabited ant

[Nov.

NATURAL SCIENCES OF PHILADELPHIA. 327

hills, with pavements still smooth and nude of grass or weeds, indicating that
they had been very recently occupied. The missing communities were all dead
— extinct — had been destroyed by a series of rainy seasons. Then, there were
but few of these ant cities to be found that were occupied. But when the
drouth set in, the earth being no longer filled with water, they began to multi-
ply very rapidly. City after city appeared as the dry weather continued, and
now, 18G3, at the close of a ten years' drouth, they have spread so extensively,
that their clean little paved cities are to be seen every fifty or sixty yards, espe-
cially along the roadsides, in the prairies, walks in yards and fields, barren
rocky places, &c. In beds of heavy grass, or weeds, or in deep shady wood-
lands, they very seldom locate a city. They prefer sunshine and a clear sky.
This ant does not work in the heat of the day during hot weather, but makes
up the lost time during the night. I have often found them busily engaged at
2 and even 3 o'clock, A. M. Before day, however, they call off the workers,
ami rest till about sunrise. In more favorable weather, when they can operate
all day, they do not work late at night.

In regard to courage, there can be no mistake in stating, that when the
interests of the nation are involved, this ant exhibits no signs of fear or dread
of any consequences that may result to self, while engaged in the discharge of
its duties.

The police or national guards of a community which has been established
three or four years, number in the aggregate, of the parties on duty, from one
to two hundred. These are seen all the time, in suitable weather, unceasingly
promenading the environs of the city. If an observer takes his stand near the
edge of the pavement, he will discover an instantaneous movement in the en-
tire police corps, coming wave-like towards him. If the observer imprudently
keeps his position, he will soon see numbers of them at his feet, and without
the slightest degree of precaution, or the least hesitation, they climb up his
boots, on his clothes, and as soon as they come to anything that they can bite
or sting, whether it be boot, or cloth, or skin, they go right to work biting
and stinging ; and very often, if they get good hold on any soft texture, they
will suffer themselves to be torn to pieces before they will relinquish it. If
they succeed in getting to the bare skin, they inflict a painful wound, the irri-
tation, swelling and soreness of which will not subside in twenty-four hours.

If any worm or small bug shall attempt to travel across their pavement, it
is immediately arrested, and soon covered with the fearless warriors, who in a
short time deprive it of life. Woe unto any luckless wight of a tumble-bug who
may attempt to roll his spherical treasure upon that sacred and forbidden
pavement. As soon as the dark, execrable globe of unholy material is discov-
ered by the police to be rolling on, and contaminating the interdicted grounds,
they rush with one accord upon the vile intruder, and instantly seizing him by
every leg and foot, dispatch him in a short time. Sometimes the tumble-bug
takes the alarm at the start, while only two or three of the ants have hold on
it, expands its wings and flies off with them hanging to its legs. If it fails
to make this early effort, it very soon falls a victim to the exasperated soldiery.
The ball of filth is left on the pavement, sometimes in the very entrance to the
city. In due time the workers take possession of it, cut it into fragments, and
pack it off beyond the limits of the incorporated grounds.

I have not observed that anything preys to any considerable extent upon
this species of ant. Chickens and mocking birds will sometimes pick up a few
of them, but not often. If anything else in Texas eats them. 1 have not noticed
it. Neither have I observed their nests bored into or dug up in middle Texas.

The agricultural ant is of but little disadvantage to the farmer, however nu-
merous, as it is never seen six inches from the ground, nor does it cut or
trouble any growing vegetable outside of its pavement, except the seeds of the
noxious weeds and grasses. Sometimes it is found stealing corn meal, broom-
corn seeds, &c; but it is only when it finds them on the ground that it steals
even these.

Children occasionally get on their pavement, and are badly stung. A few of
these pavement lessons, however, generally obviate that inconvenience. The
pain of their poison is more lasting, will swell and feel harder, than that of the
honey bee. If they insert their stings on the feet or ankles of the child, the
irritation will ascend to the glands of the inguinal region, producing tumours
of a character quite painful, often exciting considerable fever in the general
system ; the irritation will last a day or two, but I have seen no permanent
injury arising from it.

During protracted spells of dry weather, they are frequently found in great
numbers in our wells. They seem to have gone there in pursuit of water, and
not being able to get back, to make the best of a bad condition — in this unfore-
seen dilemma — they will collect and cling together in masses as large as an
ordinary teacup, in which condition they are frequently caught and drawn up
in the bucket. When they are thus brought up, though they may have been
in the water a day or more, they are all living, though half drowned and barely
able to move. While in the well they are all afloat, and at least one-half the
mass submerged. As it is known that this species of ant cannot survive 15
minutes under water, how they manage when in a large half-sunken mass to
survive a day, or even longer, is a question to which I may fail to give a
satisfactory solution. I may, however, from experiments I have made
with single individuals, in water, venture the assertion that there is no pos-
sible chance for the submerged portion of the globular mass, if it remain in
r.he same condition in relation to the water, to survive even half an hour.
Then we are forced to the supposition that by some means or other the ball
must be caused to revolve as it floats. The globular mass must be kept roll-
ing, and make a revolution every four mi?iutes, or the submerged portion must
die. To accomplish this somewhat astonishing life-preserving process, there
is but one possible alternative. It can be effected only by a united and
properly directed systematic motion of the disengaged limbs of the outer tier
of ants, occupying the submerged half of the globular mass.

I saw to-day (June 15), in a clean-trodden path near my dwelling, quite a
number of this species of ant engaged in deadly conflict. They Mere strewed
along the path to the distance of 10 or 12 feet, fighting, most of them, in sin-
gle combat. In some few cases, I noticed there would be two to one engaged,
in all of which cases the struggle was soon ended. Their mode of warfare is
decapitation, and in all cases where there were two to one engaged the work
of cutting off the head was soon accomplished. There were already a num-
ber of heads and headless ants laying around, and there was a greater number
of single pairs of the insatiate warriors grappling each other by the throat on
the battle-field, some of whom seemed to be already dead, still clinging to-
gether by their throats. Among the single pairs in the deadly strife there
were no cases of decapitation. They mutually grapple each other by the throat,
and there cling until death ends the conflict, but does not separate them. I do
not think that in single combat they possess the power to dissever the head ; but
they can grip the neck so firmly as to stop circulation, and hold on until death
ensues without their unlocking the jaws even then.

The cause of this war was attributable to the settlement of a young queen
in close proximity (not more than 20 feet) of a very populous community that
had occupied that scope of territory for ten or twelve years. Ar first, and so
long as they operated under concealment, the old community did not molest
them ; but when they threw off their mask, and commenced paving their city,
the older occupants of that district of territory declared war against them and
waged it to extermination. The war was declared by the old settlers, and the
object was to drive out the new ones or exterminate them. But the warriors
of this species of ant are not to be driven. Where they select a location for a
home, nothing but annihilation can get them away. So, in the present case,
the war continued two days and nights, and resulted in the total extermina-
tion of the intruding colony. From the vastly superior numbers of the older

[Nov.

cottiers, though many of them were slain during the war, they nevertheless
succeeded in destroying the entire colony, without any apparent disturbance
or unusual excitement about the great city. Their national works and govern-
mental affairs went on in their ordinary course, while the work of death was
being accomplished by their resolute bands of triumphant warriors.

They do not interrupt, in any way that I have discovered, the small black
erratic ant, when it comes on their pavement. They even permit the erratic
ants to erect cities on any portion of the incorporated limits, and do not mo-
lest them. It may be that the little fellows serve them some purpose. But
when they build too many of their confederate cities on the pavement of the
agricultural ant, it seems to be an inconvenience to them some way, but they
do not go to war with them, nor attempt to rid themselves of the inconveni-
ence by any forcible means. They, however, do get clear of them, and that by
instituting a regular system of deceptive and vexatious obstructions. The
deception is manifested in the fact that it appears to have suddenly become
necessary to raise the mound two or three inches higher, and also to widen the
base considerably. Forthwith are seen swarming out upon the pavement hosts
of ants, who go rapidly to work, and bringing the little black balls
which are thrown up by the earthworms in great quantities everywhere in the
prairie soil, they heap them up, first at the base of the mound, widening till all
the near erratic ant cities are covered up. At the same time, they raise the
entire pavement an inch or so, and in prosecuting this part of the national
work deposit abundantly more balls upon and around the erratic ant cities
than anywhere else. The little ants bore upwards through the hard sun-dried
balls, which are constantly accumulating — getting worse every hour — until
the obstruction has become so great that they can no longer keep their cities
open ; and, finding that there is no remedy for the growing difficulty, they
peaceably evacuate the premises. There is found on almost every pavement,
at this season of the year, three or four small pyramidal mounds, that have
been constructed for the purpose of crowding out the little erratic ants.

The extensive, clean, smooth roads that are constructed by the agricultural
ants are worthy of being noticed. At this season of the year their roads are
plainest and in the best order, because it is harvest time, and their whole force
is out collecting grain for winter supplies.

I am just this moment in from a survey of one of these roads, that I might
be able to make an exact and correct statement of it. It is over a hundred
yards in length, goes through twenty yards of thick weeds, underruns heavy
beds of crop grass 60 yards, and then through the weeds growing in the locks
of a heavy rail fence 20 yards more ; and throughout the whole extent it is very
smooth and even, varying from a straight line enough, perhaps, to lose 10 or
12 yards of the distance in travelling to the outer terminus. It is from 2 to 1\
inches wide ; in some places, on account of insurmountable obstructions, it
separates into two or three trails of an inch in width, coming together again
after passing the obstruction. This is the main trunk, and it does not branch
until it crosses the before-named fence, beyond which is a heavy bed of grain
bearing weeds and grass. Their prospecting corps travel far out, and when
they discover rich districts of their proper food they report it, and a corps of
foragers are immediately dispatched to collect and bring it in.

11th June, 1863. — My son, Dr. Leonidas, called my attention to an assem-
blage of the males and females of the agricultural ants (Myrmica molefaciens)
which took place about 2 P. M., and continued in session until 4 P. M. They
were all winged ants, and there were many thousands, perhaps millions, of
them, -thickly covering the ground over an area of 10? yards in length and 10
wide. They came from all directions, and were evidently the production of
many kingdoms of this wonderful species of ant. There must have been, at
least, five males to one female, and all parties were rushing hither and thither
over the entire area, described above, in a frantic, amative furor. Each female
would be found covered and wallowing on the ground with clusters of from

1866.]

330 PROCEEDINGS OF THE ACADEMY OF

four or five to twenty males ; and there were hundreds thickly rushing over
the ground in search of females that were not to be found. The air was full
of them flying around, going off and returning; some of them, perhaps, just
arriving.

When a female became satisfied with her numerous lovers, by a great and
violent effort she made shift to extricate herself from their rude embrace and
immediately fly away. After 4 P. M. they began rapidly to fly away, and in the
course of an hour they were all gone, leaving their disconsolate, exhausted
lovers, who made no effort to follow. Many of the males were already dead,
and a still greater number^Jay helpless on the ground ; but there were hundreds
of thousands who were still active, and they collected together in the horse-
tracks, cracks in the ground, and other places sheltered from the south wind,
which prevails at that season of the year, and becoming perfectly quiet, were,
at G P. M., lying still in heaps of from half a pint to a quart, sometimes more.
At this hour I examined the entire field, and there must have been very near,
if not quite, a bushel of the exhausted and dying male ants.

A strong south wind was blowing during the time the females were flying off,
and the larger portion of them were drifted by the wind into the timbered lands
to the north ; many of them, however, succeeded in forcing their way a few
hundred yards against the wind, and alighting, which seemed to be the effect of
fatigue more than desire, they immediately, by writhing and doubling them-
selves in various ways, cast off their wings, which were no longer necessary,
and running rapidly till they found a' little clean spot of earth, went hurriedly to
work digging holes in the ground, which they accomplished with apparent ease
and considerable facility. They dig and bring out the dirt in considerable pel-
lets with their large caliper-like mandibles, carrying it not exceeding two inches
and dropping it in a circle around the hole they are making ; very soon they had
buried themselves out of sight. Two hours after they had commenced flying
away from their lovers, hundreds of holes, with a little circle of black dirt
around them, might be seen. In every clean-trodden piece of ground, and in
the roads and paths, these new tenements were thickly set long before sun-
down.

Only one of these mother ants is necessary to start a kingdom. I saw no
instance where two of them were at work at the same hole. In some favorable
spot of ground there would be found a great many of them at work excavating
their holes, sometimes within a foot of each other. None seeiued to know that
any other ant was near. While one was out with a load of dirt, I placed a stick
in her hole ; returning, she did not know the place, and in searching around
soon found another one's hole, into which she immediately plunged. Very soon
the owner of the establishment pushed the intruder out, who made battle as
soon as they were fairly out on level ground. The conflict soon became despe-
rate, and after they had fought for the space of a minute or two the intruder
seemed to give way, and, extricating herself from her highly incensed antagonist,
plunged into the hole again ; the owner followed, and after some time succeed-
ed in dragging the invader out once more; and also, after a dire conflict, in put-
ting her to flight. The victor went to work again, but in the fight she had been
injured, as I noticed every time she came out with a load of dirt she would stop
awhile, and with one of her feet rub and fix something about her mouth. She
seemed to be in pain, and did not work so vigorously as before the fight.

It would not do for many of these new queens to prove successful in building
up kingdoms. There is some antagonistic action to prevent it. The male and
female congress, I have attempted to describe above, happens two or three times
every year, arid should all the queens succeed in establishing colonies, they
would in a very few years occupy the entire surface of the earth.

This species of ant — and I think it obtains with the whole genus, like the hor-
net, wasp, yellow jacket, &c. — do not go off from the old hive in swarms like the
bee, but a single mother ant, after congress with the males, goes off alone and
sets up for herself. She works very busily until she has raised 20 or 30 neuters

[Nov.

NATURAL SCIENCES OF PHILADELPHIA. 331

to work for her, when she ceases to labor, and, remaining in-doors, lays all the
eggs that produce the coming millions. The laborers are long-lived, so are the
queens.

28th.— I extract from my journal : This morning I found the males where 1
left them last evening. The greater portion of them were still active, and
seemed to be quite careless as to their fate. Hundreds were dead or dying.
Great numbers had climbed up the little weeds, many of whom were dead, but
still clinging by their jaws, which were fast gripped to some little leaf or twig.
The females had buried themselves by the time it was dark last night, and,
closing up their holes, remained shut in all night. But few of them had opened
their doors and gone to- work at an hour by sun this morning. The number of
their holes is truly wonderful. I saw many places where there were at least
fifty of their holes to the square rod, and northwardly they extended for miles.
When these mother ants succeed in boring their holes to the depth of six or
seven inches they close them up, and employ themselves widening the bottom
of them a little, forming small cells for the purpose, as I suppose, of making
room for the deposition of their eggs. They do not, as I can discover, need
any food yet. At 5 P. M. of this day I visited the place again, and found the
male ants all dead. They were drifted into the gullies by the winds into
heaps, and thousands of them besides lay scattered over the ground. Some of
the females were still engaged deepening their holes, and their little piles of
black dirt were to be seen everywhere.

29th Jul;/. — A month has passed. I went round to-day and found that, in
all those thousands of female ants, who made so brave a start excavating new
homes, there was but one that was a success, and it was concealed with a little pile
of trash. There may be more, but I did not find them, and the winds have swept
away their little piles of dirt, so that there are no signs of them left. From
some cause they are all gone. Eight or ten days after they had shut up their
holes I dug up quite a number of them ; found them looking well, but they
had no eggs or anything else in the little cell. They seemed to be sleeping.

I have never witnessed similar assemblages in any other species of ant,
though I have seen it often take place with the agricultural species.

macular row upon tbefore wings is almost obsolete, except the spot upon the
inner margin, which is prolonged into a dash.

Hind wings marked as in Asterius 9, but the blue clouds between the yel-
low bands are reduced to small rounded patches, insensibly diminishing to the
outer angle ; that upon the abdominal margin is lunulate and covers a ful-
vous crescent, not ocellate as in Asterius ; tail not so long as in that species ;
emarginations white ; expanse 3*5 — 4 inches.

Below much paler ; primaries with a series of submarginal rounded yellow
spo's, and between these and the cell another of large fulvous sagittiform
spots ; a minute yellow spot on the end of the cell ; one, somewhat larger,
above the origin of the fourth subcostal veinlet.

Secondaries as in Asterius, with the exception of the anal mark, which is
simply a lunule as on the upper surface, and of the existence of a very minute
fulvous spot within the cell, rarely obsolete, always much less than the cor-
responding one in Asterius; the yellow emarginations are also considerably
narrower than in that form.

Hal. — Mexico. Coll. Entom. Society.

A very remarkable approximation to our most common species of Papilio,
and indeed the general similarity existing in color and form has been almost
sufficient to induce me to regard it as only a singular aberration, or a well
marked local race.

Upon a closer and structural examination, however, we discover the follow-
ing points of difference in this most essential particular.

First, the antennae of Asterius are fully a line longer than in the new type ;
secondly, the fourth subcostal veinlet is thrown off one-third nearer the cell
than in our endemic species ; thirdly, in it the cell is broader than in the
corresponding tf, and the disco-cellular veins ot equal length ; fourthly, upon
the secondaries the upper disco-cellular does not form so great an angle with
the second subcostal, and the intervals between the median veinlets are
larger, consequently the cell is both broader and longer.

This adds a fourth member to that group of segregated forms, ranging over
the largest portion of central and southern North America, and consisting
heretofore of Asterius, Aristor, and Indra.

Mr. Win. H. Edwards is in possession of a beautiful new species from Ari-
zona, belonging to the same series, which I hope he will soon describe.

28. Lycjena isola, nov. sp.

Upper surface brownish black, glossed with violet blue ; a black terminal
line, broadest at the apex of the fore wings, thence diminishing to the anal
angle ; a small rounded, submarginal black spot near the latter ; fringe
white.

Underneath dark ash grey : primaries with two submarginal, slightly
waved whitish lines ; interior to these a row of six large rounded black spots,
all ringed with white ; two white streaks at the end of the cell.

Secondaries with a submarginal row of indistinct brown spots, of which the
three nearest the anal angle are black, the first and third irrorated with me-
tallic golden-green atoms, and the third surmounted by a yellowish lunule ;
all the others are preceded by whitish crescents ; above these there is a suf-
fused white belt, and still farther, two double rows of waved and crenulated
whitish lines ; a small subcostal black ocellus near the base.

30. . Thecla zoe, nov. sp.

Male. Upper side brilliant, shining blue, a black border of moderate width
on the primaries, broadest at the apex ; narrower upon the secondaries, which
have two tails, the inner being the longest and tipped with white ; there is
the usual smooth sexual spot at the end of the fore-wings' cell, and obliquely
below, and connected with it a large black patch.

Underneath brown tinged with purplish ; on the primaries a submarginal
band of obsolete dashes and a sinuated median row of six black spots extend-
ing from the costa to the first median veinlet.

This, most beautiful as well as one of the largest species of its genus, does
not assimilate closely with any of its associates.

I have many other new species ot this genus, which I hope to figure at
some future time ; it is impossible to describe them.

At the time that I wrote the " Notes upon Exotic Lepidoptera," &c, I had
had no opportunity of consulting any of Dr. Folder's numerous writings in
the " Wiener Entom. Monatschrift." I have now to regret having redesoribed
several of his species; an error which, however unfortunate, from uselessly
multiplying difficulties in the correct determination of species, is scarcely to
be avoided when two Entomologists are working upon the same subject at the
same time. I append their corrected nomenclature, together with some other
synouymical reciificatious.

A species of considerable range, and presenting slight modifications through-
out, which, however, are not local or confined to particular sections. These
are well expressed by Dr. Felder, 1. c, p. 27, and may be briefly stated
thus. — In the varying size of the white or yellowish white spot between the
two last median veinlets of the fore wings, and also in the width of the sub-
triangular green band ; in the presence of one or two greenish streaks of dif-
ferent lengths within the cell above the white spot, and in the longer or
shorter red spots upon the hind wings.

The only difference between Dr. Felder's excellent figure, and the speci-
mens in my possession, and the cabinet of the Society is, that his aristomenes
has a white dash above the subcostal vein of the primaries — absent in all
which I have seen. I do not doubt but that they are identical. I do not
believe that tonila is the 9 of caleli, as indicated by Dr. FeMer in his
Speci<s Lepidopterorum, p. 296, n. 107 (1864) ; it is more nearly related to
the $ of int/lotes, Gray, than cahli is to the ^ of that species.

Pap. caleli and tonila belong to a group of nearly allied forms of peculiar
facies, all inhabiting the northern parts of South, or the tropical portions of
North America ; their co-members are mijlotes, Gray, timias, Dbldy., and
eurimedes, Cram. ; the last, possessed of the greatest range, is most probably
the parent stock of the other and segregated species.

NATURAL SCIENCES OF PHILADELPHIA. 343

There are numerous other cold and warm springs that issue from the sur-
face in every direction, but not deep or large enough to give a fair average
temperature. The water of these springs deposits on the surrounding ground
and stones a saline efflorescence of a pure white, and with a soda or saline
taste. Several of the hot springs are continually depositing a tufa, which has
formed around them all dome-shaped hillocks, with basin-like cavities in the
centre, from which the water, mingled with a constant rush of bubbles of gas,
boils up like a seething caldron. The waters have an acid taste not unpleas-
ant, with decidedly chalybeate qualities, which approximate it very much to
the famed Congress Springs of Saratoga, N. Y. Iron is deposited by several
of the springs, giving a reddish tinge to the tufa. The springs are situated from
three to thirty feet above the level of Soda Creek, a clear cold mountain stream,
with gravelly bed ; for a long distance below the springs, the gravel in the bar
and bed of Soda Creek are cemented by the tufa deposited by the hot springs.
It has evidently been always a place of resort for the mountain sheep (Ovis mon-
tana,) mountain goat (Capra Amer.) and buffalo (Bison Amer.) who delight to
lick the incrustations and drink the waters of these springs. This is shown by
their numerous bones found above and under ground near the springs. Indeed,
as late as Jul}' 3d, 1860, three mountain sheep were killed near these springs.
In the springs, both hot and cold, confervas and a few grasses grow ; no fish, how-
ever, are found in them; no Crustacea except perhaps one about 1^ inches long,
which is found in the hot springs, and which has a hard covering and rudiment-
ary legs. This insect, crustacean, or whatever it may be, is very much of
the color, size and shape of the kind found in Great Salt Lake, by Captain
Fremont, in 1843 — 44.

The flora of the neighboring region to these springs is rather scanty,
and comprises the following more common species :
Juniperus communis. Sesleria dactyloides.

Juniperus virginianus. Bromus, sp. undet.

Pinus variabilis. Poa, " "

Pinus fraseri. Elymus hystrix.

Salix tristis. Helianthus, sp. undet.

Populus angulata. Aster, 2 sp. undet.

Populus tremuloides. Cynoglossum, sp. undet.

Alnus incana. ^Euchroma coccinea.

Cornus sericea. ^Cactus opuntia.

Solidago secunda ? Astragalus, 3 sp.

Stanleyi integrifolia. Baptisia, 1 gp. undet.

Camelina, 1 sp. Sisymbrium, 1 sp.

Draba, 2 sp. Barbarea, 1 sp.

Calochortus luteus. Fragaria virginiana.

Sorbus, sp. undet. Rubus spectabilis.

Spiraea, " " " idaeus.

Rosa, " " Ribes floridum.

Vaccinium, sp. undet. Ribes, 2 sp. undet.

What, however, renders the locality of the Hot Soda Springs still more re-
markable, aside from their singular character, and the picturesque scenery
of their surrounding location, is the following fact recently developed :

About the last days of September, 1800, two miners, who had been for two
months and a half opening a mining^ claim about 200 yards S. W. of the springs
and at the foot of the hill marked on the map^oda Hill, reached at last in the
gravel, boulders and rocky deposits of Soda Bar, a depth of 22 feet; here at
this depth and about 3 yards from the foot of the hill slope, they found a human
skeleton, lying on its face and imbedded in a deposit of gravel, sand, small
boulders, and fragments of the adjacent rock in situ, which from 2 feet below
the surface in this locality yields a very fine rich quality of coarse gold. The
skeleton, all whose larger bones, though very light and porous, were yet intact,
and whose skull was also entire, was in a very tolerable state of preservation •

under the skeleton and about 2 feet lower down, they found upon the sur-
face of what the miners call "red rock," the trunk, limbs and roots of a small
pine tree, identical in all respects with the red pine (P. variabilis) of the adja-
cent slopes ; the bark appeared charred and blackened, the wood was light,
yellow and apparently sound, showing the fibrous woody structure, the knots,
the annual rings of growth, identical with variabalis : on exposure to air, how-
ever, it soon became soft and crumbled, more like rotten, or water soaked wood.
The roots and limbs appeared as if violently compressed or forced in the seams
of the underlying rock. There, then, was a point conclusively shown, namely,
that prior to the cause which covered Soda Hill, Soda Bar and Dry Diggings
Hill with its enormous beds of gravel, sand and boulders, and its native gold,
(which is eveiywhere sought for in this locality, from the lowest points of
Payne's and Illinois Bars, 2\ feet above Clear Creek up to the highest points
where it can availably be mined and hauled to water) man roved and dwelt in
this region, timber grew, and everything requisite to furnish food to mankind
and the brute creation must have flourished in proximity. Here then we have,
within the period of man, evidence that either the convulsions which caused
the emergence of the Rocky Mountain range in Western Kansas is a very late
geological phenomenon, or that some sudden cause, the upheaval per-
haps of the higher Central range, through the metamorphic granite, the talc
and mica slates of the lower Eastern ranges of the Rocky Mountains, scooped
out the low interior mountain basin in which the Gregory, Russell, Nevada,
Lake and other gulches now mined and populated are located ; and that then,
as the floods, be they of mud, water, or snow and ice, caused by the disturbed
equilibrium of the older chain of mountains, by the sudden emptying of Moun-
tain Lakes perhaps, or by the sudden melting of snows and deluges of rain,
then subsided, and the vast fissures through which Clear Creek now finds its
way into the Platte gave way to the pent up waters ; then perhaps the receding
waters, still carrying a vast amount of detritus as the waters subsided, left them
in their present location. Indeed, one is at once surprised at the location of
the so-called Pike's Peak Gold Mines of Gregory and Clear ('reek.

After looking over a lofty mountain road for 16 miles, we descend from 1000
to 2000 feet into an interior mountain basin, surrounded on all sides by mountain
ranges of much greater altitude, and through which but one avenue has been
opened, where Clear Creek or Vasquez^Fork of Platte river finds its way into
the vast prairies extending from the foor of the mountains to the Missouri river.
Perhaps it may be urged that glacial phenomena may account for this anoma-
lous fact. In answer we can say that, from the evidence before us, the climactic
condition of the present time, carried out by the identity of the long buried
flora of the period when this convulsion took place with the one now in ex-
istence, forbid us from supposing that the Central range (or Snowy range, more
commonly so-called.) was ever the seat of Glaciers large or extensive enough
to cause phenomena at all adequate to explain the changes and erosions now
so plainly seen in the valley of Vasquez Fork, or in the upper mining region.
The lofty summits of Long's and Pike's Peaks, the intermediate lofty chain, the
high mountains between Clear Creek and Bear Creek, although they retain in
places deposits of snow and small beds of ice, yet nothing is ever found upon
them answering the appearance of constant glaciers, whose accretion in cold
summers and diminution in warm summers write upon the bare mountain
peaks a history of their force and continued action. As a proof of the recent
date of the convulsions that have in ages'past furrowed and torn up the Plu-
tonic rocks of the east side of the range, that have upreared the tertiary strata
at the foot of the mountains, until their almost perpendicular strata form a
secondary valley parallel with the valley of the South Platte and has spread
over the vast plains of the Platte and Kansas Rivers, the boulders, gravel and
sand formed of Feldspathic granite, it is interesting and valuable, and may
be a guide, a clew to the solution of the question by which the valley of the
Platte, the interior prairie of South Park, the complete want, over a vast ex-

draining and disappearance of vast bodies of fresh water ; whatever cataclysm
buried this member of the human family, be he Aztec, Indian, Esquimaux or
Mound builder, he is for the region above mentioued, " homo diluvii testis."
We confess that our preconceived notions of the antiquity of this globe have
received a severe shock by this discovery, and have modified our views of the
relative antiquity of the strata of this globe and the age of this part of the con-
tinent ; with a wish that some more able pen will help to elucidate this strange
point, we present these few fads.

List of COLEOPTEEA collected in the Mountains of Lycoming County, Pa.
BY JOHN L. LECONTE, M. D.

During the first week of June, 18GG, I had the good fortune to make one of a
party who visited Lycoming County, to indulge in the pleasure of trout-fishing.
Our station was on the Loyalsoc Creek, about thirty miles from Williamsport.

The collection contained so many species not previously known in Pennsyl-
vania, that it has seemed to me, though small in extent, to merit particular con-
sideration ; the more so, because it indicates the necessity of greatly-increased
collections in the mountain regions, before we can begin to map out accurately
the distribution of our species. The names correspond with those in my list
of North American Coleoptera.

Some of the more interesting new species, belonging to groups which I have
already investigated, I have named. The descriptions will be found in the fol-
lowing pages of this volume. Two of them I have dedicated to members of
the party, who, although unknown to the literature of science, appreciate
enthusiastically the beauties of nature ; and manifested, by their ardent pur-
suit of the finny game, and their accurate knowledge of his habits, such natu-
ral taste for scientific employments, as would, doubtless, had earlier oppor-
tunity favored, have much diminished the labor yet to be performed by stu-
dents of Zoology in this country.

List of COLEOPTERA collected near Fort Whipple, Arizona, by Dr. Elliott

Coues, U. S. A., in 1864—65.

BY JOHN L LECONTE, M. D.

At the request of Dr. Coues, it was my intention to prepare a catalogue of
the Ooleoptera, thus far known from Arizona. On reflection, it seems to me
that such a list would be at present of but little value to entomologists ; partly
because all the species previously examined by me are mentioned in my memoir
on the Ooleoptera of the U. S. and Mexican Boundary,* but still more, because
Dr. G. H. Horn, recently Surgeon of California Volunteers, having spent four
years in collecting through California and Arizona, has returned with much
new material. Any list of species now made would, therefore, soon be ren-
dered useless by the investigation of his collections. For these reasons I
have confined myself to a list of the species submitted to Mr. Dike and myself
by Dr. Coues. The new species are described with others iu the present num-

Revision of the DASYTINI of the United Scates.
BY JOHN L. LECONTE, M. D.

Having recently had occasion to examine all th e species of D a s y t i n i in
my collection, I have detected among specimens received since the publica-
tion of my previous memoir, in 1852, several undescribed species. In order
to fix more definitely the characters, not only of the new species, but of those
previously described, I have prepared a sketch of the genera and analytical
tables of the species before me.

Much of the Pacific district yet remains unvisited by collectors, and a large
increase in the number of representatives of this tribe may be expected from
future eypiorations.

In all the genera found in our territory, as far as known to me, the terminal
spurs of the anterior tibiae are very small. They may be tabulated as follows ;

A. First joint of tarsi not shorter than the second;

(claws of tarsi equal in length, second and
third joints of tarsi not dilated, and last joint
of palpi not securiform in any of our genera):

Anterior tibiae with an external row of spines Pristoscelis.

Anterior tibiae without spines :

Membranous appendages equal, nearly as long

as the claws ; in great part connate.. Listrus.

Appendages connate ; one long, the other shorter Dolichosoma.

One appendage long, connate, the other denti-
form All onyx.

Both appendages short, connate, usually denti-
form Dasy tes.

Membranous appendages long, equal, free to the

base Eschatocrepis.

B. First joint of tarsi shorter than the second Melyris.

On comparing this table with those of European genera, as given by
DuVal* and Kiesenwetter,f it will be seen that the characters here ascribed
to Listrus correspond with those of Lob onyx, and those of Escha-
tocrepis with those of Haplocnemis. The differences will be men-
tioned under the respective genera.

PRISTOSCELTS Lee.

Under this name I have grouped the species of North America, in which
the anterior tibiae are furnished with a distinct series of spines on the outer
margin. Important differences in pubescence and form exist among the spe-
cies, which have, so far as they were known to him, been distributed by
Motschulsky into genera, which he has named Byturosomus (Group I.), Tri-
chochrous (Group II.), and Emmenotarsus (Group III.) In order to avoid a
change of gender in the specific names of the species thus far described, I
have arbitrarily made the generic name masculine, instead of feminine, as
required by a strict adherence to classical construction.

The following table expresses the relations between the species before me :

erect hairs 1. f u s c u s.

-» Group I. Byturosomus Motscb.

But one species of this group is known to_ me. It is of oblong oval form,
rather more robust than the other species ; the prothorax is twice as wide as
the head, and in the male is wider than the elytra ; it is wider than long,
broadly rounded on the sides, and obliquely subsinuate each side at the base;
the angles are all rounded. The pubescence of the thorax is less dense than
that oi' the elytra ; a few longer suberect hairs are intermixed with the pros-
trate ones. The front tibiae are longer than usual, slender and slightly
curved in the male, and the row of small spines on the outer side is very
distinct. The appendages of the claws are broad, and connate with the claw ;
the outer one is free for a very short distance.

griseus Motscb. Bull. Mosc. 1859, ii., 395. B. rufipes Motscb. ibid.

Vallecitas, San Diego County, California ; May. The differences between
the sexes are. so great that unless found together they might be readily con-
sidered distinct species ; in the male the thorax is wider than the elytra, and
much less densely pubescent ; the elytra are gradually narrowed from the
base; the abdomen is composed of six ventral segments, and the front tibiae
are elongated, and curved inwards : in the female the body is not attenuated
behind, the thorax is as wide as the elytra, gradually narrowed in front, aud
densely pubescent ; the abdomen has but five ventral segments, and the ante-
rior tibite are not curved. In both sexes the fourth joint of the antenna' is
narrower than the fifth, though somewhat triangular.

Col. Motschulsky has by some accident interchanged the names of D.
fuscus and D. griseus Lee. Of the latter I had but a single specimen,
and was therefore unable to furnish him with a type; D. fuss us, on the
contrary, was collected by me in large numbers, and has been freely distri-
buted.

Group II. Trichochrous Motsch.

In this group the body is elongate, or elongate oval, the thorax not more
than one-hnlf wider than the head ; the pubescence is prostrate without any
intermixed hairs, though in some species (antennatus, brevicornis,
&c.) clothed with long and coarse pubescence, the hairs lie less closely on the
surface than in the others. The characters given in the synoptic table will
enable the species to be recognized without difficulty.

2. P. ater. Pristoscelis atrus Bland. Proc. Ent. Soc. Phila., iii., 253.
Abundant near San Francisco. This species ditfers from P. 1 a t i c o 1 1 i s

by the larger size, by the thorax being more distinctly transverse, with the
sides less rounded, and the posterior angles more distinct, although obtuse;
the sides of the thorax, as in the next two, are fringed.

cence being more dense, and less fine ; from P. 1 a t i c o 1 1 i s it differs by the
thorax being much less rounded on the sides, more emarginate at the apex,
causing the anterior angles to be quite distinct, and the hind ones less ob-
tuse.

type of this species; other specimens were found by Mr. G. Davidson at Cape
Keyes. The thorax is wider than long, much rounded on the sides, equally
narrowed at base and apex, with the hind angles indistinct.

5. P. ful vi tar sis Bland, Proc. Ent. Soc. Phila., iii., 254.

Middle California, Mr. Ulke A slender species, still smaller than the pre-
ceding, with the thorax scarcely wider than long, fringed with long hairs on
the sides, which are broadly rounded, and with the hind angles distinct, ob-
tuse. rlhe antennae are black, and the legs testaceous, with the thighs some-
what darker. In the male the sixth ventral segment is visible ; the fifih joint
of the antenna? in both sexes is wider than the sixth, and the fourth joint is
triangular, rather broader than long.

Fort "Whipple, Arizona, Dr. E. Coues, U. S. A. The autennse are as long as
the head and thorax ; the third joint is slender, and longer than the fourth,
which is somewhat triangular; the fifth is not wider than the sixth ; the
eleventh is one-half longer than the tenth, oval and subacute at tip. This
species in color resembles P. fulvitarsis, but is much larger, with the
thorax slightly narrowed in front, and the legs of a uniform bright reddish-
yellow. The anterior tibia? on the outer margin are armed with 5-7 small
spines.

One specimen from Fort Whipple, Arizona, Dr. Coues. This species closely
resembles the preceding in size, form and sculpture, but the pubescence is
yellowish, and the antenna? and oral organs are not black but reddish-yellow.
The color is brownish- black, with a faint metallic tinge, and the humeri are
distinctly reddish brown. The antenna? are out little longer than the head,

NATURAL SCIENCES OF PHILADELPHIA. 353

Mas segmento ventrali sexto prominulo, profunde foveato.

Two males, Fort Crook, California, Dr. G. H. Horn. It resembles in form
P. convergens, but that species is much larger and uniformly pubes-
cent, whereas in the present species the coarse pubescence on the elytra is
intermixed with somewhat longer suberect hairs of the same color ; the long
erect hairs observed on the head and thorax of the species of the next divi-
sion are wanting, and I have therefore regarded it as properly placed next to
P. convergens.

9. P. an t en n at us. Trichochrous ant. Motsch. Bull. Mosc. 1859, ii. 394.
Dasytes griseus Lee, Proc. Ac. Nat. Sc. Phil., vi. 169.

One specimen found by me at San Diego, Cal. ; others from the plains near
the Rocky Mountains were given me by Mr. Ulke. This species is easily re-
cognized by the thorax being broader than long, gradually but strongly
narrowed in front, with the sides feebly rounded, and the hind angles obtusely
rounded ; the elytra are coarsely punctured, and clothed with long brownish
pubescence; the antennae are piceous, somewhat paler at base ; the fifth joint
is obviously wider than the sixth in the female, and the feet are ferruginous ;
The last ventral segment of the male is longitudinally broadly impressed, a
character I have not observed in any other species of the present group.

10. P. brevicornis. Dasytes br. Lee, Proc. Acad. Nat. Sc. Phil., vi. 169.
San Diego and Middle California. The pubescence is coarse, and the sides

fringed with very long hairs ; the thorax is broader than long, equally nar-
rowed at base and apex, with the sides much rounded ; the elytra are coarsely
and more densely punctured than in the preceding ; the antennas are piceous,
sometimes nearly testaceous at base ; the third joint is scarcely narrower
than the fourth.

11. P. erythropus. Dasytes erythropus Lee, Pr. Acad. Nat. Sc, vi. 170.
Texas. The pubescence is coarse and dense, and the sides of the thorax

somewhat serrate ; the spines of the anterior tibiae are small, and not very
distinct, so that this species might readily be referred to Listrus. Its
natural affinity seems to be, however, with the preceding, from which it dif-
fers by the narrower form, by the thorax being more strongly rounded on the
sides, with the base not at all wider than the apex, and by the much less
coarse punctuation of the elytra.

Group III. Emmenotarsus Motsch.

The species of this group resemble in form those of the preceding, but
differ in having long, erect, black hairs intermingled with the finer prostrate
pubescence ; in b r e v i p i 1 o s u s, however, the erect hairs are gray, and but
little longer than the pubescence, so that without careful examination they
might be overlooked. The row of spines on the outer margin of the anterior
tibias is more conspicuous than in most of the species of the preceding group.
The sixth ventral segment of the males is visible and concave beneath.

Middle California. A species of more cylindrical form than usual, and
easily known by the mtermixed hairs of the elytra being of the same color as
the pubescence, and scarcely longer than it.

Cape San Lucas, Lower California, collected by Mr. Xantus. In the male
the bead is but little narrower than the thorax, the antennae are longer than
the head and thorax, strongly serrate, with the third joint triangular, not
narrower than the fourth or fifth ; in the female the thorax is about one-half
wider than the head, the antennae are shorter than the head and thorax,
moderately serrate, with the third joint narrow, and the fourth triangular, but
not as wide as the fifth. The intermixed erect hairs are of the same color as
the pubescence, but much longer.

14. P. sordid us. Dasytes sordidus Lee, Proc. Acad. Nat. Sc. Phila., vi.
169.

'San Diego, California. The pubescence is as coarse as in the preceding,
and the intermixed hairs as long, but the thorax is considerably rounded on
the sides, and not narrowed anteriorly ; and the antennae palpi and legs are
black.

15. P. suturalis. Dasytes sut. Lee, Proc. Acad. Nat. Sc. Phila., vi. 169.
San Diego, California. The pubescence is cinereous, and fine, more dense

at the suture, sides and tip of the elytra, which are more finely and densely
punctulated than in the allied species ; the thorax is narrowed from the base
to the tip, the sides very feebly rounded and slightly serrate, the base broadly
rounded, and the hind angles well marked, and somewhat obtuse. The elytra
in the male are Dot wider than the thorax at base, and gradually narrowed
behind. The third joint of the autennae is scarcely triangular, the fourth is
slightly dilated, but not so wide as the fifth. The female only differs from
the male by the elytra not being narrowed from the base, and by the anten-
nae being a little shorter.

16. P. quadricollis. Dasytes quadr.~Lec, Proc. Acad. Nat. Sc. Phila.,
1859, 75.

Fort Tejon, Cal., Mr. Xiin'us. Easily recognized by the thorax being quad-
rate, with the sides scarcely rounded, subsinuate behind, with the posterior
angles rectangular, not rounded; the base is broadly rounded, as in the pre-
ceding species.

17 P. tejonicus, elongatus, niger, fenescens, pube longiuscula minus

haud rotundatis ; elytris thorace latioribus, sat dense punctatis, pedibus saepe
nigro-piceis. Long. 2-5 — 4 mm.

Fort Tejon, California, Mr. Xantus. The pubescence is coarser than in the
neighboring species, but less so than in P. s o r d i d u s. It differs from P.
quadricollis by the sides of the thorax not being sinuate behind, and
from P. conformis, &c, by the more distinct hind angles and less rounded
sides. The feet in several of the specimens before me are dark brownish.

18. P. conformis. Dasytes conf. Lee, Proc. Acad. Nat. Sc, vi. 169.

San Diego. The pubescence is gray, and not very fine, and in some speci-
mens is denser at the suture and sides of the elytra, as in P. suturalis.
The sides of the thorax are strongly rounded, and the hind angles indistinct;
the elytra are not wider than the thorax and the punctures are finer than in
P. aenescens, and about as in quadricollis an^ Tejonicus.

19. P. squalid us. Dasytes sq. Lee, Proc. Acad. Nat. Sc. Phila., vi. 169.
Differs from the types of P. conformis only by the gray pubescence

being more dense, and the sides of the thorax a little less rounded, and by
the smaller size.

Two specimens, Oregon, Dr. G. H. Horn ; the sixth ventral pegment is visi-

scence, and the tibia5 and tarsi are pale.

21. P. aenescens. Dasytes xn. Lee, Proc. Acad. Nat. Sc, vi. 170.

San Diego and the Islands off Santa Barbara. The pubescence is very fine,
and the intermixed black hairs numerous ; the thorax is a little wider than
long, more rounded on the sides than in the preceding, but with the hind
angles somewhat distinct; the elytra are a little wider than the thorax, and
much more coarsely punctured than in the allied species.

Santa Catalina Island, California; five specimens in bad condition. Much
smaller than P. aenescens, with tbe thorax less transverse, and the sides
gradually converging, and less rounded before the middle.

The erect hairs are nearly all rubbed off in the specimens before me, but 1
think that the species belongs to the present group.

23. P. grandiceps, elongatus, aeneo-niger, pube subtili cinerea minus

elytris thorace vix latioribus, sat dense profunde punctatis. Long. 5 mm.

Middle California; one specimen given me by Mr. Ulke. As usual, the
under surface is densely clothed with cinereous hair; the large size of the
head enables this species to be recognized at first sight.

24. P. pedalis, elongatus, nigro-aeneus, pube subtili cinerea sparse

tis et transversim subrugosis ; antennarum articulis 2 — 4 piceis, pedibus fer-
rugineis vel piceis. Long. 3-5 — 4 mm.

Santa Catalina Island, California. This species has the usual form, the
thorax being more than one-third wider than the head, and resembles in ap-
pearance P. T ej o n i cu s ; it is distinguished by the red or brown feet, and
the more strongly rounded sides of the thorax. In the specimens with dark
feet the tibiae and tarsi are paler than the femora, which are sometimes
nearly black ; such specimens may be distinguished from P. conformis
by the finer cinereous pubescence and the more strongly punctured elytra,
and from P. aenescens by the thorax being as wide as the elytra.

Two specimens, Texas. Differs from all the preceding species of this group

1866.]

by the stronger punctuation of the head and thorax. The form is about the
same as that of the preceding; the antennae are shorter than the head and
thorax, with the third joint slender, and the fourth not as wide as the fifth.

26. P. r u f i p e n n i s. Dasytes ruf. Lee, Proc. Acad. Nat. Sc. Phila., 1858.
71.

Arizona, Mr. Schott, one specimen. Much larger (6 mm.) than any of the
preceding, and remarkably different, by the elytra being rufous, and as finely
punctured as in P. suturalis. The tborax is equably, tolerably strongly
punctured, very little narrower than the elytra, wider than long, much rounded
on the sides, broadly rounded at base, with the hind angles obtuse, rounded
and not distinct. The scutellum and a small portion of the suture are black.
The erect hairs and pubescence are in great part wanting, but enough re-
mains to show that both are cinereous. The feet are rufous, and the anterior
tibia? are armed with a very distinct row of spines on the outer side. The
antenna? are wanting in the unique specimen before me.

27. P. serricollis, niger nitidus, pube pallida parca elongata vestitus,
pilis erectis nigris pallidisque intermixtis, capite modice punctato, thorace

latius rotundata ; elytris thorace baud latioribus fortiter sat dense punctatis,
rufo-testaceis ; anteunis nigro-piceis pedibus rufis. Long. 5-5 mm.

Two males, New Mexico and Colorado. The sixth ventral segment is not
excavated. Of the same size as P. r u fi p e n n i s, but quite distinct by the
form of the thorax, which is but little wider than its length, very much
rounded at the sides and apex, and more broadly rounded at the base, with
the hind angles not very distinct. The sides are strongly serrate, especially
in front of the middle. The black hairs are long on the thorax, but on the
elytra the pubescence is intermixed with pale erect hairs, only a few black
ones being seen.

Arizona, Dr. Irwin. U. S. A. The joints of the antennas 4 — 10 are gradu-
ally wider and obtusely rounded at tip. The spines on the outer margin of
the anterior tibiae are distinct, but less prominent than in the preceding
species.

LISTRUS Motsch.

The chief difference between this genus and the preceding is to be found
in the anterior tibiae, which have not any spines on the outer margin. The
appendages of the claws are broad, as long as the claws themselves and connate
with them almost to the tip ; in this as well as in the form of the palpi and
antennae it agrees with Pristoscelis ; the thorax is scarcely one -half wider
than the head, and is always serrate and fimbriate at the sides ; the pubes-
cence is uniform in texture, without any intermixed erect hairs.

The characters correspond with those ascribed to the European genu
Lobonyx, in the works of DnVal and Kiesenwetter, except that the antenna
are distinctly serrate, with the eleventh joint oval and not constricted at the
middle.

The sexual characters are not observed in the anterior tarsi as in Lobo-
n y x, but in the fifth and sixth ventral segments, which are more or less fove-
ate or excavated in the male.

The species in my collection may be separatedvas follows :

Dasytes canescens\ Lee. Proc. Acad. Nat. Sc. Phila., vi. 170.

Middle California, abundant; Oregon. I take pleasure in naming this
species after Col. Motschulsky, who has mentioned, Bull. Mosc. 1859, 391, the
error I committed in referring it to the species described by Manuerheim. It
differs by the more robust form, larger size, more transverse thorax and more
densely punctured elytra.

In the male the sixth ventral segment is prominent, but not excavated, the
fifth is not excavated. In the female the sixth ventral segment is not visible.

2. L. interruptus, elongatus aeneo-niger, pilis pallidis longis sericeis
irregulariter vestitus, thorace latitudine paulo breviore, antrorsum angustato,

elytris thorace paulo latioribus, fortiter punctatis, transversim subrugosis,

One pair, Nebraska, Mr. Ulke ; one specimen, Santa Cruz Island, Califor-
nia, Mr. C. M. Bache. I should hesitate to consider this as distinct from the
preceding, but for the sexual characters. The fifth ventral segment of the
male is broadly emarginate, clothed behind with velvety black hairs, and the
sixth segment is prominent and concave.

The only differences I can find between this and L. Motschulskii are :
the thorax is a little more convex and less transverse, the elytra comparatively
a little wider, and the denuded fasciae are interruptsd so as to form spots ;
and the second joint of the antennae is piceous.

.Middle California ; for authentic types of this species I am indebted to Col.
Motschulsky. The thorax is nearly round, serrate on the sides, the denuded
bands of the elytra are not interrupted into spots, and the antennas are
entirely black. The fifth ventral segment of the male is deeply excavated,
emarginate and clothed behind with black velvety hair, the sixth segment is
prominent and concave The antennae are described by Mannerheim as rufo-
teslaceous at base, but they are entirely black in the specimens sent by Col.
Motschulsky.

4. L. diffi cilia. Dasytes cliff. Lee, Pr. Acad. Nat. Sc. Phila., vi. 170.
San Jose, California. This species is narrower than L. Motschulskii

or in t err u p t u s, and of the same form as the preceding, from which it
differs by the hand behind the middle of the elytra being broad and scarcely
angulated. The sixth ventral segment is visible in both sexes, but in the
male the fifth is marked with a deep rounded medial fovea.

5. L. rotundicollis. Dasytes rot. Lee, Pr. Acad. Nat. Sc. Phila., vi. 1 70.
San Jose, California. Differs from all the preceding by the pubescence

being much shorter and less unequally distributed, so that the spots on
the elytra become obsolete. The thorax is scarcely wider than long, narrowed
in front, moderately rounded and serrate on the sides, broadly rounded at the
base; the elytra are slightly wider than the thorax, and somewhat more
coarsely punctured than in the foregoing species. The sixth ventral segment
is visible in both sexes, but in the male the fifth segment is excavated nearly
to the base, and the excavation is fringed with black velvety hairs, and the
sixth segment is depressed in the middle.

6. L. lute i pes. Drtsytes lut. Lee, Pr. Acad. Nat. Sc. Phila., vi. 170.
Southern portion of California ; San Diego, Fort Tejon. The feet and

antennae are ferruginous, the outer joints of the former are fuscous. The
thorax is as long as its width, moderately rounded at the sides, which are
serrate as usual ; the elytra are a little wider than the thorax, strongly punc-
tured, with the spots near the base smaller, and the transverse bands wider
than in the other species ; the pubescence is long and coarse. I observe no
sexual character in the four specimens in my collection.

cription of L. punctatus Motsch., 1. cit. 390, agrees with my specimen,
except that the antennae and feet are entirely black ; while in the description
cited the second and fourth joints of the antennas, the tip of the tibiae, and the
tarsi are stated to be " plus minusve testaceo-piceis."

1 refer to this genus two species in which one claw is furnished with a
connate appendage as long as itself, and free only at the tips, and the other
with a short appendage, rounded at tip, leaving the outer half of the claw
free. The second species shows a character not observed in any Pristoscfdis
or Listrus ; the thorax each side about half way between the middle and the
lateral margin is marked with a distinct longitudinal line.

Nebraska, near the Rocky Mountains, and northwards. A slender, dark
blue species of large size, having the third joint of the antennae triangular,
and nearly as large as the fourth, which is equal to the fifth. The pubescence
is very fine, cinereous and sparse, intermixed with erect black hairs. The
sixth ventral segment is prominent in both sexes ; the fifth is broadly emargi-
nate at tip, and excavated in the male, the excavation being bounded by an
elevated ridge each side.

clothed with prostrate cinereous hair ; the thorax is more than one-half wider
than long, and considerably rounded at the sides, which are distinctly ser-
rate ; the antennae are black, with the third and fourth joints triangular, but
a little narrower than the fifth. The thighs are piceous, the tibiae and tarsi
paler. I should have referred this species to L i s t r u s, but for the fact tiiat
the appendage of the outer claws is as long as the claw itself, and entirely
connate, while that 'of the inner claw is about two-thirds as long, obtusely
rounded at tip, leaving the tip of the claw free.

ALLONYX Lee.

This genus agrees in character with Dolichosoma, except that the outer
claw is slender, with a feeble dentiform dilatation at base: the inner claw is
furnished with a broad obtusely rounded appendage connate almost to
the point of the claw* in the first species, and entirely masking the point in
the second. The mandibles are acute at tip. The antennae are shorter than
the head and thorax, feebly serrate, with the third and fourth joints nearly
cylindrical, and narrower than the fifth. The thorax is marked with a deeply
impressed transverse line near the base, which bends forward each side, and
extends to the apex, forming thus a longitudinal furrow, about one-third dis-
tance from the lateral margin. The sixth ventral segment is prominent and
impressed in both of the specimens before me.

1. A. sculptilis Lee, Class. Col. North America, 193. Dasyles sculptilis
Lee, Proc. Acad. N#. Sci. Philada., 1859, 75.

One specimen. Fort Tejon, California ; Mr. Xantus. The pubescence is
very fine and sparse; the thorax transverse, not narrowed in front, sides
rounded in front, sinuate behind, with the hind angles rectangular and pro-
minent. The elytra are nearly parallel on the sides, and the tip is broadly
rufo-testaceous ; the antennae, palpi aud legs are rufo-testaceous, the hind
femora blackish at tip; the palpi are also blackish at tip ; the inner claw is
free at tip. Somewhat resembles a small Trogosita in appearance.

One specimen from Colorado, given me by Dr. S. Lewis. Quite different in
appearance from the preceding. It is possible that dissection would indicate
a relationship between this genus and Danacea of the other continent;
but the want of sufficient material prevents me from making the investiga-
tion.

DASYTES Fabr.

In this genus are to be included the following species, which, although
differing in appearance, agree in having the tarsal claws similar in form,
acute at tip, and armed with a basal dilatation, or a rounded lobe shorter
than the claw itself. The sixth ventral segment is prominent in both sexes.
Our species may be arranged as follows:
Thorax with a deeply impressed lateral line.

Basal dilatation two-thirds as long as the claws 1. hudsonicus.

Basal dilatation one-half as long as the claws 2. b r ev i u s c u 1 us.

* By a ty|> graphical error in the table of genera (Class. Col. N. Am., 193) tlie appendage of the
claw is described as " narrow, and free almost to tlie base." The line defining A 11 o n y x should
not have been indented.

One male collected in Hudson Bay Territory by Mr. R. Kennicott, given me
by Mr. Ulke. The antennae are as long as the head and thorax ; the second
joint is as long as the third ; the third is narrower than the fourth, which is
triangular and equal to the fifth. The ungues at the base are dilated into an
obtuse rounded lobe, which leaves only one-third of the claw free. The sixth
ventral segment is prominent, and deeply excavated.

This species wouid be quite as well placed in Group III ofPristoscelis,
except that no spines are visible on the outer side of the anterior tibiae ; the
general appearance, as well as the sculpture of the thorax, indicate an affinity
with the next species, from which it differs by the finer mmctuation and pu-
bescence, and by the sides of the thorax being slightly Disinuate, feebly an-
gulated at the middle, and not serrate.

2. D.b r e v i u s c u 1 u s Motsch., Bull. Mosc. 1859, ii. 396.

One female, California ; given me by Mr. A. Murray. My specimen differs
from that described by Col. Motschulsky in having the antennae and feet of a
uniform black color; but as will be seen in the descriptions of other species
of this tribe, these characters are not constant, and I therefore consider the
specimen before me as belonging to his species. The pubescence is coarser
than in the preceding, and the black hairs are not very obvious ; the thorax
is more sparsely and quite finely punctured at the middle, and more rugosely
at the sides, which are broadly rounded and slightly serrate; the elytra are
less finely punctured ; the ungues are armed with a lobe, which is obliquely
truncate at tip, and leaves one-half of the claw free.

Two specimens from Nebraska, given me by Mr. Ulke, differ from the Cali-
fornian specimen by the sparse punctures of the middle of the thorax being
less fine. I am unwilling to regard them as indicating a distinct species.

three others the antennae are entirely black, and the feet, especially the hind
thighs, are dark.

[Dec.

NATURAL SCIENCES OF PHILADELPHIA. 361

Several badly preserved specimens from Sta. Catalina Island agree in sculp-
ture, but the sides of the thorax are much more rounded, the legs are nearly-
black, and the elytra are less coarsely punctured. If is a little smaller, being
1*6 mm. long. It may be named D. catalina?.

The dilatation of the claws in»both species is broad, and about half as long
as the claw.

ESCHATOCREPIS Lee.

In this genus the appendages of the claws are as long as the claws, narrow,
rounded at tip, and free quite to the base. In this respect it agrees with the
European genus Haplocnemis, but differs by the antennae being scarcely
serrate, gradually thickened externally, with the fifth joint, as in several spe-
cies of Pristoscelis, slightly wider than the contiguous joints.

The thorax is not wider than long, feebly rounded on the sides from the
base nearly to the tip, where they are slightly sinuate, thus rendering the
anterior angles somewhat prominent ; the disc is feebly channelled, and
marked each side with a deep impressed line extending from the tip to the
base.

Additions to the COLEOPTEEOUS FAUNA of the United States. No. 1.
BY JOHN L. LECONTE, M. D.

It is my intention, from time to time, to publish descriptions of the new spe-
cies which have been obtained too late for insertion in the " List of the Coleop-
tera of North America," and the "New Species of North American Coleoptera,"
in course of publication by the Smithsonian Institution. As the parts of those
two works now in print treat of the same families as are contained in Part I.
of the " Classification of the Coleoptera of North America," published by
the Institution, the papers of this series will be confined within the same
limits. Any interesting discoveries in the succeeding families, in which the
penultimate joint of the tarsi is connate with the last joint, (Tetramera and
Trimera of the Latreillean method,) and in the Rhynchophora, will be de-
ferred, or made known only in faunal memoirs.

The descriptions of individual members of genera and families are in the

362 PROCEEDINGS OF THE ACADEMY OP

present state of progress of Entomology very undesirable ; the complication in
bibliography and the difficulty of reference being sources of greater injury
than the advantage resulting from the knowledge of the species thus published.
And the motives which induce me, on the present occasion, to violate my well-
established opinions of what is best for the interests of science are ; first, the
number of genera not previously represented in our territory; and secondly, by
numbering the papers in a regular series, to render them really supplements to
the " List " and " JSTew Species " above mentioned. At the same time I shall
rigidly exclude from this series any species which can be described in any
monographic or faunal memoir which may soon be elaborated. Varieties or
races of described species which have not been previously noticed in print will
also be mentioned.

Since the publication of my last descriptions of Coleoptera, the metrical
system of weights and measures has been adopted and authorized by the
Government of the United States. The measurements used in the present
series are millimetres, and can be converted approximately into hundredths of
an iaeh, (the measure used in my previous memoirs,) by multiplying by four.

CICINDELA Linn.

1. C. obsoleta Say. A remarkable variet}', or rather race, of this species
was collected at Fort Whipple, Arizona, by Dr. E. Coues, U. S. A. It is of
large size, (19 mm.,) dark blue color, tinged with green, the thorax less flat-
tened than in race p r a s i n a , but less convex than in race vulturina, with
the pale, markings of the elytra perfect, as in the best developed specimens of
the latter: viz., a humeral spot, a submarginal spot before the middle, a medial
band not attaining the margin, composed of two spots connected by an oblique
line, an apical lunule, consisting of a terminal margin dilated into a spot
anteriorly about one-fifth of the length of the elytra; the legs and under sur-
face are dark blue, with the last ventral segment black.

2. C. longilabris Sen/. A variety of this species occurs in Colorado, in
which the color above is dark brown slightly bronzed, the humeral lunule
entire, connected with the medial band by a narrow submarginal white line,
and the apical lunule entire and dilated anteriorly into a large spot. The
under surface and legs, as usual, are blue green. For a specimen I am indebted
to Dr. S. Lewis.

3. C. nigroccerulea Lee. Mr. Ulke has a specimen of this species,
from Colorado, in which the color above is dull leek-green, and the elytra are
immaculate.

4. C. rufiventris Dej. Chaudoir (Cat. Coll. Cicindelites, 1865,) con-
siders C. 16-punctata and C. cumatilis as varieties of this species.

5. C. dorsal is Say. Chaudoir (loc. cit.) regards C. media Lee. and C.
Saulcyi Guerin as varieties of this species. I have in the list already placed
the former as a race of C. d o r s al i s, but the much smaller size, and the
less development of the tooth on the right mandible of the male, seem to
establish the specific nature of C. Saul cyi.

G. C. repanda Dej.. C. 12 -guttata Dej. is placed by Chaudoir as

a variety of this species.

7. C. obliquata Rirby, as I learn from a drawing
made by Mr. Andrew .Murray, from the type in the
British Museum, is quite distinct from any species known
to me. The annexed wood cut will show the character of
the markings better than any description. The species
should hereafter be known as C. K i r b y i.

[Dec.

NATURAL SCIENCES OF PHILADELPHIA. 363

8. C. f o r m o s a Say. Chaudoir regards C. generosa Dej. and venusta Lee.
as being varieties of this species.

9. C. rugifrons Dej. Besides the races indicated by me in the List,
Baron Chaudoir places as a variety of this species C. scutellaris. From
this view I must dissent, regarding the finely and densely rugous prothorax of
the latter as constituting an essential difference between the two.

10. C. rectilatera Chattel., Bull. Mosc, 1843, 69.3, is the species found
in Texas which I erroneously considered as C. d e c o s t i g m a, and subse-
quently proposed to name C. t e x a n a (List, p. 1 ).

11. C. purpurea Oliv. Chaudoir places C. splendida as a variety
of this species.

12. I learn from Mr. Sall6, as well as from Baron Chaudoir's Catalogue, that
the species described by me, Tr. Am. Phil. Soc. xi. 62, as C. viatica Chew.,
is different from that species. It may be called, from its locality, C. pime-
r i a n a.

BLETHISA Bon.

B. multipunctata Dej., Sp. Gen. ii. 266. A specimen which, on close
comparison with European specimens, shows no difference, was found at
Ottawa, C. W., and presented to me by Mr. B. Billings. Two others from the
neighborhood of Chicago are in the collection of Mr. Ulke.

NEBRIA Latr.

N. o bl i qu a, alata nigra, thorace longitudine duplo latiore postice angus-
tato, lateribus antice rotundatis, postice obliquis hand sinuatis, basi truncata,
angulis posticis obtusis baud rotundatis, canaliculate, antice profunde trans-
versim impresso ad basin fortiter impresso et parce punctato ; elytris oblongis,
thorace latioribus, striis subpunctatis, 3io puneto pone medium impresso :
autennis palpis tarsisque piceis. Long. 11 mm.

Colorado. I have seen two specimens belonging to Dr. S. Lewis, one of
which he has generously placed in my collection. In form this species
resembles N. moesta, but the sides of the thorax are not sinuate near
the base, the hind angles, though well marked, are not rectangular but
obtuse, the elytra are less convex, and the third interval has but one im-
pressed puncture, which is on the third stria, about one-fourth from the tip.

CYCHRUS Fabr.

C. Guyotii, ameo-niger, thorace latitudine hand longiore, postice valde
angustato, lateribus anguste fortiter marginatis, disco rugoso postice punctato ;
elytris ovalibus convexis, anguste marginatis, dense crenato-striatis. Long.
27 mm.

LeConte, List of the Coleoptera of North America, p. 58, (1st issue, 1863).
One specimen collected among the Black Mountains of North Carolina, was
given me by Prof. A Guyot. A remarkable species, resembling in its characters
C. Andre w s i i, but as large as C. v i d u u s.

The specimen is a female, and on comparison with the same sex of C.
A n d r e w s i i, it is found to differ not only in size and by the more coarse
punctures of the base of the thorax, but also by the labrum being less
elongate, the lobes less slender, the emargination more broadly rounded, and
not extending so near to the base as in that species ; the sides of the thorax
are distinctly angulated near the middle.

Le Conte, List of the Coleoptera of North America, p. 58, (1st issue, 1863).
One specimen, collected near San Francisco. California, given me by Dr. G.
H. Horn. This species is related to D. mar in us Lee, but is much stouter in
form ; the thorax is comparatively larger, and the elytra more obviously sub-
truncate.

The publication of subsequent pages of the work, in which the descriptions
of this and the preceding species first appeared, has caused the page above
quoted to be cancelled, and I have therefore rendered any future reference
to it unnecessary by transferring them to the present memoir.

APEXES Lee.

A. nebulosa, depressa picea, opaca, capite thoraceque confertim
rugosis et subtiliter punctatis, hoc latitudine sesqui breviore canaliculato
postice angustato, angulis posticis obtusis distinctis, basi sinuatim rotundata ;
elytris thorace sesqui latioribus, striis impunctatis, interstitiis planis, 3io bi-
punctato, fuscis, limbo lato fasciisque duabus obliquis obscure testaceis ; abdo-
mine testaceo, antennis palpis pedibusque pallidioribus. Long. 6-5 mm.

Cape San Lucas. Lower California ; Mr." Xantus Of the same size as A.
s i n u a t a, but quite different in color, lustre and sculpture. The elytra are
rather broader than in the other species, and the oblique pale bands are not very
distinct ; the anterior one runs backwards towards the suture, and the pos-
terior one runs forward, producing a resemblance to the markings in some
Bembidia of the group Nolaphus. The antenna? are scarcely as long as the
head and thorax united ; the claws are feebly pectinate, each being armed
with two to three teeth. The rugosities of the head are longitudinal, and
quite densely placed, with some intermixed punctures.

RHOMBODERA Reich.

R. b i c o 1 o r Lee. I have two specimens from Illinois, which differ from
the type by having the head black; they are thus intermediate in color
between R. pallipes, in which the head and thorax are black, and R.
b i c o 1 o r. in which both are yellow. I prefer regarding all as belonging to
one species.

PTEROSTICHUS Bon.

P. superciliosus. Feronia superc. Say, Journ. Acad. Xat. Sci. Phila., iii.
144, ed. Le Conte, ii. 92.

A specimen from West Virginia, 15 mm. long., given me by Dr. S. Lewis,
differs from P. moestus in having the thorax less narrowed behind, the
hind angles more broadly rounded and feebly carinate ; the basal impressions
finely punctured, separated from the reflexed margin by the feeble carina just
mentioned; the elytra are much less obtuse behind, shining, (at least in the
male,) deeply striate and tinged with purple; the third interval has four punc-
tures, as in P. m o e s t u s. The outline is nearly the same as in P. s t y g i -
c u s, but the thorax is somewhat more narrowed behind.

In Say's description of Feronia superc. the base of the thorax is said to be
"wider than the petiole," and in the description of F. moesta, "not wider than
the petiole." The descriptions otherwise accord with each other, and the
other distinctive characters between P. moestus and the specimen before
me are not mentioned ; yet, as the original types of F. sitperciliosa are
destroyed, I prefer rather to adopt the name than to regard the species under
consideration as a nondescript.

The form and sculpture of the thorax is nearly the same as in P. p r o -
t e n s u s Lee, (Xew Species of X. Am. Col., 12,) but the form in that species
is more elongate, the elytra are more deeply striate, not tinged with purple,
and there are but two dorsal punctures.

scuro, thorace utrinque linea arcuata ad basin extensa impresso, elytris utrin-
que subtiliter biseriatim punctatis ; antennis extrorsum, tarsisque piceis.
Long. 3 mm.

One male, California, Mr. Ulke. Of the same size and form as H. punc-
tatus and cuspidatus, but rather more obtuse in front, and very distinct
by the epistoma not being margined in front, and by the thorax each side being
marked with a deep curved line, concave inwards, extending from the middle
to the base. This line is twice as distant from the middle as from the side, and
meets the base at an obtuse angle. The pale markings of the elytra consist of
a basal band, another behind the middle, and an apical spot ; the bands are
composed of short lines more or less confluent, and are dilated at the margin
into larger spots ; the epipleuras are testaceous ; the usual lines are composed
of small crowded punctures, the surface is finely reticulate, and towards the
suture small sparsely scattered punctures are visible, which become obsolete
towards the sides.

H. 12-lineatus Lee. and H. scitulus Zee. are the only other species
in my collection having the thorax similarly impressed, but the lines in them
are less acutely defined, and the body is not rounded.

H. vitiosus Lee. A male specimen from Texas, sent me by Mr. Salle,
agrees in form and arrangement of colors with the female type from Illinois,
but differs by the punctuation, which is quite strong, and not dense, nearly as
in the male of H. oppositus. The agreement in other respects is so com-
plete that I would not be justified in regarding it as belonging to a different
species.

H. sellatus, ovalis convexus, modice elongatus, nitidus, subglaber, ca-
pite nigro-piceo subtiliter baud dense punctato, ore maculaque occipitali tes-
taceis, thorace testaceo, apice infuscato, basi late piceo, profunde punctato,

cis, plagaque postica irregulari subsuturali maxima nigris ; subtus niger, rude
punctatus, pedibus testaceis, antennarum apice femoribusque infuscatis. Long.
35 mm.

One specimen from Dacota, given me by Mr. Ulke. This species has the
same size and nearly the same form and sculpture as H. s u t u r a 1 i s Lee, but
is more equally attenuated in front and behind, and the punctures of the elytra
are somewhat finer and more dense ; the pale yellow elytra, with the large black
posterior spot, will enable it to be easily recognized. The spot extends from
before the middle to within a short distance of the tip, and from the suture
three-fourths way to the sides ; the anterior outline is formed by the confluence
of two short lines, and the exterior outline is lobed ; the whole suture is black-

ish, and the same color extends along the inner portion of the base ; a small
discoidal brownish line is seen before the middle, and nearer the side than the
suture ; the punctures are tolerably dense and deep, and in the position of the
usual lines are seen a few scattered larger punctures ; the epipleurse are pale.
The body beneath is very coarsely punctured, as in H. suturalis and allied
species.

COLYMBETES Clairr.

C. notatus Sturm. Dytiscus not. Fabr. I have a male specimen, found in
Montana, which agrees with the figures and descriptions of this common Euro-
pean species. The head is black, with the front part and two spots on the ver-
tex pale. The thorax is pale, with a transverse medial black spot; the basal
and apical edge are narrowly margined with black ; the sides are rounded and
do not form a perceptible angle with the outline of the elytra. The elj-tra are
pale, thickly and coarsely irrorate with black, leaving the suture and two al-
most obsolete lines on each pale ; scutellum black. Body beneath black, legs,
prosternum, abdominal sutures and large apical spot testaceous. This species
is smaller and more convex than C. b in o t a t u s, and on account of the broadly
rounded sides of the thorax is more obtusely rounded in front, more parallel on
the sides, and more acute behind. The ungues of the anterior and middle feet
are very unequal, the inner one being one-half the length of the outer one,
which on the front feet is nearly straight.

A male from North Red River, and a female from Idaho. This species has
nearly the form of the preceding, but is less convex ; and is easily known by
the absence of the vertical spots, and by the color of the under surface. The
inner claw of the front tarsi of the male is scarcely shorter than the outer one ;
they are slightly sinuous, but nearly straight.

San Francisco, Mr. Bolander. Differs from II. oblong us Lee. by the tho-
rax being more strongly punctulate, narrowed behind, with the hind angles less

middle, the angle of which is directed forwards. The granules at the side of
the thorax are more distinct, and are marked with a central puncture.

Pennsylvania, New York and Lake Superior. There are five specimens be-
fore me. This species differs from the European species, except L. atom u s,
by the distinct sutural stria, which extends from the tip to within one-third of
the base. I have observed no sexual difference in the legs. The last two ven-
tral segments of the male are connate, forming a plate, which is triangularly im-
pressed at the base, but rounded and ciliate with long hairs at the tip.

NECROPHORUS Fabr.

N. Hecate Bland, Proc. Ent, Soc. Phila., iv., 382.

Kansas and Colorado. This species resembles in the form of the thorax N.
Melsheimeri Kirby, but differs by the smaller size, the less finely punctured
head and thorax, and by the deeper dorsal channel of the latter ; the red mark-
ings vary in size, being sometimes as in N. m arginatus and Melshei-
meri, except that the black extends slightly upon the epipleurje behind the
humeri ; and sometimes so broad that the two bands become united, leaving
only the base, apical margin, small common sutural spot, sutural margin
behind the middle, and another small lobed spot near the side, black. The
club oYthe antennas is entirely ferruginous. Length 11-5 — 20 mm.

I have received, through the friendly attention of Mr. A. Murray, sketches of
the thorax, elytra and antennas of N. ob scums and hebes Kirby; the
former does not appear to be different from that which I have recognized as N.
M e 1 s h e i m e r x^Kirby ; the hind trochanters are emarginate in the female,
but the inner angle is recurved in the male. N. h e b e s is a species unknown
to me, differing from N. marginatus and Melsheimeri by the club of
the antennas being entirely black, and the posterior red band being represented
by a large irregular spot, touching neither the side nor the suture ; the epi-
pleurae, as in the species named, are entirely red.

N. confossor Lee., Proc. Acad. Nat. Sc. Phila., vii. 19.

From Oregon. Appears to be a -variety of N. m a r i t i m u s Mann., with
very broad markings ; the red bands are as broad as in N. marginatus or
N. Melsheimeri, from which it differs by the thorax being scared}' nar-
rowed behind, and with a wider depressed margin ; the first joint of the antennal
club is black, as in N. Melsheimeri, and the hind trochanters of the
female are emarginate, while, as in that species, the inner angle of the male is
strongly recurved.

N. p y g m ae u s Kirby. In the List of Coleoptera of North America I have
incorrectly placed this as a synonym of N. mortuoru m, from which it dif-
fers by the absence of the red spot at the base of the epipleurae.

N. defodiens Mann, seems to be a larger form of N. pygmoeus,
with narrower markings. I have specimens from Oregon, intermediate in size
between the very small Canadian form and the large specimens found in Rus-
sian America.

S. opaca Lmn. The occurrence of this species in Arctic America, on the

Keokuk, Iowa, Dr. Brendel. This species agrees with the figures and
descriptions of the European L. testaceus, and I have had no opportunity,
by comparing specimens, to observe the differences which probably exist.

My object in describing the species is not only to make known the dis-
covery of the genus on this continent, but to call attention to some hitherto
unnoticed characters which seems to indicate that its place is not in the family
Silphidae, in which it has been thus far classed.

The head resembles very much that of a Hydrophilide, Philhydrus or Cer-
cyon, for instance, the upper surface being slightly convex, not narrowed
anteriorly, but broadly rounded, both on the sides and in front; the labrum is
broad, transverse and not prominent, the mandibles do not project; the anten-
nae are inserted on the under surface of the sides of the front, slender, longer
than the head and thorax ; the first joint is as long as the two following united,
the second is shorter, but scarcely thicker than the third ; the outer joints are
very slightly thickened ; all the joints appear equally opaque and pubescent ;
the eyes are entirely wanting ; the mentum is large, slightly concave, with the
hind angles acute, produced backwards over the gula, forming small carinas ;
the suture between the mentum and gula is distinct, but not as obvious as
usual ; the prothorax beneath is quadrately emarginate in front, s© that
the anterior angles project under the head; the anterior coxae are oval or
rounded, not prominent ; the cavities are open behind, almost separated by
the prosternum, and externally furnished with a narrow fissure, to the end of
which the prosternal suture runs ; the middle coxae are small, separated by a
narrow carinated mesosternum ; the trochantin is visible, and the side pieces
extend to it ; the hind coxae are flat, and not very large ; the tibial spurs are
long and slender, and all the tibiae are sparsely spinous ; the tarsi are all five-
j.ointed, and the fourth joint is slightly oblique beneath, and furnished with a
dense brush of hairs ; the first joint of the hind tarsi is as long as the three
following united ; the abdomen is flat, with the sixth joint short, but distinct.

It is to be observed, from the notes given above, that this genus differs from
Silphidae by — 1st, the form of the head, and the insertion of the antennae,
2d, the form of the mentum, 3d, the form and arrangement of the anterior
coxae, 4th, the structure of the fourth joint of the tarsi ; all of which are
characters of fundamental importance. It agrees with Hydrophilidae in the
form of head, insertion of antennae, general arrangement of mentum, gula
and prosternum, but differs by the regular antennae, not prominent anterior
coxae, aud structure of the fourth joint of the tarsi. The relations with
Mycetophagidae, to which it bears a superficial resemblance, and Cryptophagi-
dae, are too remote to be worthy of analysis. With Nitidulidae, especially the
genera having large mentum, it might also be considered to have some
affinity, but the fourth joint of the tarsi is not small, the anterior coxae
have no trochantin, and their coxal cavities are partially confluent and open
behind.

I therefore infer that Leptinus is a highly specialized type, representing a
distinct family, having less affinity with Silphidae than with Hydrophilidae.

Dr. Brendel observes in a letter, " This insect I found under a log in a mouse
nest, in company with fleas ; in the neighborhood were yellow ants, of the
same kind with which C e o p h y 1 1 u s lives."

One specimen, Illinois. This species has the form and almost the sculpture
of Hydnobius. It differs from all the other species in my collection by the
punctures of the intervals being as large and nearly as close as those of the
striae of the elytra, which thus appear thickly punctured in rows ; the trans-
verse ruga? are very fine, and not very distinct ; the carina of the mesoster-
nuni is finer than usual, but quite distinct.

The species upon which I have established this new genus resembles, in
form and sculpture, a broad A n i s o t o m a, but differs by the antenna? having a
much larger club, in which the eighth joint is wanting, and the last joint nar-
rower than the preceding. From Cyrtusait differs by the first joint of the
club being as wide as the two following, and by the mesosternum being
carinated.

Florida, one specimen. The interior outline of the hind thighs is nearly
straight, armed with a minute tooth at the middle, and the apical angle is
rounded and prominent. The specimen is probably a male.

CYRTUSA Er.

To this genus belongs Amphicyllis picipennis Lee, New Species, p.
25. I am indebted to Mr. Ulke for specimens, which enable a more careful
examination to be made than was possible with the unique type ; the hind
thighs of the male are armed beneath at the apex, with a large and broad
tooth, acute, but not recurved at the tip. It differs from C. e g e n a Lee,
not only by size, color and sculpture, but by the legs being less thickened.
and by the tarsi being nearly filiform, while in C. e g e n a they gradually
diminish from base to tip ; the body is also somewhat contractile in C. e g e n a,
as in L i o d e s, but scarcely so in C. p i c i p e n n i s. The eighth joint of
the antenna? is not visible in either species.

COLENIS Er.

InC. impunctata Lee. the joints of the tarsi are 5, 4, 4 ; the anten-
na? distinctly 11-jointed, with the seventh joint wider than the eighth, but
smaller than the 9th ; the eleventh is elongate, oval and somewhat acutely
pointed at tip.

In C ? 1 a? v i s Lee, the tarsi are slender, with the joints 4, 3, 3 ; the mesos-
ternum is carinated ; the eighth joint of the antenna? is scarcely narrower than
the seventh ; the ninth and tenth are wider and larger, subtransverse ; eleventh
much larger oval, subacute at tip, and marked beyond the middle by a trans-
verse line ; the body is feebly contractile. These characters indicate a genus
intermediate between G o 1 e n i s, and Agaricophagus, for which the
name Aglyptus may be adopted ; it is distinguished from both genera by the
upper surface being smooth and impunctured, and by the front being finely
margined, both at the sides and anteriorly.

and more suddenly narrowed from the middle to the apex.

The genus will be easily distinguished among the Scydmaenidaj bj- the nar-
row body and approximate moniliform antenna?. The elytra are shorter than
the abdomen, leaving the pygidium exposed as in Eutheia.

remarkable ; in the female the punctures are large and deep, and about as
closely placed as on the elytra ; in the male the punctures are replaced by
elevated smooth granules, and the disc is very broadly depressed, or slightly
concave. The antenna? in both sexes are longer than the head and thorax,
moderately thickened externally, brown, with the basal joints reddish. The
head is black shining, coarsely punctured each side, and smooth in the middle ;
it is but slightly narrowed behind. The thorax is transverse, about one-half
wider than the head, rather flat, with all the angles rounded ; the dorsal chan-
nel is well marked. The elytra are coarsely and deeply punctured. The ab-
domen is moderately strongly but sparsely punctured ; the punctures are evenly
distributed in the female, leaving only a narrow apical margin of the segments
smooth ; but in the male they are accumulated at the base and sides of the
segments, leaving a wide apical margin and medial space smooth.

In one specimen the elytra are blackish only at the sides and tip, the rest of
their surface being ferruginous.

much thickened externally; the joints 1 — 3 are nearly equal in length ; 4 — 10
somewhat shorter and gradually thicker, the outer ones but slightly wider than
their length ; eleventh twice as long as the tenth, pointed at the end when
viewed laterally. The thorax is much wider than the head, flattened, nearly
twice as wide as its length, very feebly channelled, rounded on the sides, es-
pecially before the middle, broadly rounded at the base. Hind angles obtuse,
not rounded, but not very well marked ; a feeble transverse impression is seen
near the middle of the base. The elytra are as long as the thorax. The dorsal
ventral segments are more finely punctulate than the thorax and elytra, nearly
smooth towards the extremity, and furnished with erect long hairs ; ventral
segments finely punctured, margined behind with testaceous. Feet and palpi
uniform reddish testaceous.

Another specimen from the same locality is paler, the abdomen being of the
same color as the head and thorax, with a fuscous cloud on the fourth — sixth
dorsal segments ; the hind angles of the thorax are less obtuse and very well
marked, the base being feebly sinuate near the sides. There is no conspicuous
difference otherwise, and I am disposed to regard it as the male of the type.

kindly given to me by Mr. B. Billings, which does not differ from the descrip-
tions and figure of this species. I have had no opportuniry of comparing it
with European specimens.

TACHYPORUS Grav.

T. maculicollis, piceus, modice elongatus, antennis, palpis, pedibus,
elytris thoraceqne testaceis, hoc macula dorsali picea notato, elytris abdomi-
neque subtiliter punctulatis et pubescentibus, hoc nigfo-pilosello, segmentis
dorsalibus ventralibusque postice testaceo-marginatis. Long- 3-25 mm.

Two specimens, Quebec, Canada ; Mr. W. Couper. This species is less
elongate than T. j o c o su s, the abdomen being scarcely longer than the elytra,
which are about one-fourth longer than the thorax. The color, as above de-
scribed, will enable this species to be readily recognized. In the male the pe-
nultimate ventral segment is acutely emarginate, and the last segment pro-
longed; in the female the last dorsal is acutely four-toothed.

T. maculipennia, piceus, minus elongatus, antennis, palpis, pedibus,
thoraceqne testaceis ; elytris subtiliter punctulatis et pubescentibus, vitta sub-
marginali, gutta dorsali pone basin, apiceque testaceis ; abdomine nigro-
pilosello, subtiliter punctulato, segmentis postice testaceo-marginatis. Long.
2-75 mm.

One female specimen from Louisiana was given me by my lamented friend,
Dr. Schaum. This species is more robust than the preceding, and the abdo-
men is a little shorter than the thorax. The last dorsal segment is retracted,
and acutely four-toothed.

A female from Illinois, given me by Mr. Ulke, is 4 mm. long, with the abdo-
men conspicuously longer than the elytra ; the black markings of the latter are
reduced in size, so that the ground color is pale, with a common scutellar spot,
a large discoidal blotch, and a marginal elongate spot remain blackish. I
believe it to belong to the same species as the type above described. The last
dorsal segment is acutely four-toothed.

CONOSOMA Kraatz.

C. Knoxii, elongatum convexum, subtiliter sericeo-pubescens, capite

articulis 4 — 9 piceis, externis crassitie longioribus. Long. 3-5 mm.

One specimen, Lycoming County, Pennsylvania. I have dedicated this beau-
tiful species to my friend Joseph Knox, of Pittsburgh, whose genial manners,
and well rewarded exertions in capturing specimens of trout added greatly to
the enjoyment of the excursion in which I discovered this and other interesting
additions to the fauna of Pennsylvania.

The species of Conosoma (Oonurus Er.) in my collection agree very nearly
in form and sculpture, and are to be distinguished by size and color rather than
by structural differences. Several are still undescribed, but the present species
may be easily recognized by the characters above given.

STICTOCRANIUS Lee. (n. g. Staphylinida?).

S. puncticeps, elongatus piceus nitidus, capite grosse punctato, fronte
transversim emprcsso, margine antico elevato; thorace obovali, capite paulo
angustiore, latitudine longiore, convexo lsevi, punctis utrinque 7 magnis cana-
liculaque brevi media insculpto; elytris hevibus punctis magnis 3 vel 4 versus
suturam alterisque paucis dorsalibus insculptis; abdomine immarginato parce
punctulato ; antennis pedibusque piceo-ferrugineis. Long. 2-30 mm.

Two specimens of this remarkable insect were found by Mr. Ulke, near Wash-
ington, D. C; one of them he has liberally placed in my collection. This new
genus is related to Euaesthetus and E d a p h u s, having the tarsi 4-jointed,
as in those genera ; but it differs from both by the peculiar sculpture above men-

tinned, by the more elongate form, and by the abdomen being not margined.
One species of Eusesthetus described by Erichson possesses the last mentioned
character, but has the same sculpture as the other species. The antenna? in
S t i c t o c r a n i u s are not as long as the head and thorax, the second joint is
thicker than the third, which is equal to the fourth : 5 — 8 rounded, nearly equal,
ninth very slightly larger, tenth and eleventh broader, the former nearly square,
the latter one-half longer, obtusely rounded at tip. The head is large, wider than
its length, moderately convex, very coarsely punctured; the front is trans-
versely impressed, and the anterior margin is elevated ; the eyes are moderate
in size, not very prominent, and are coarsely granulated. Thorax a little
longer than wide, obovate, gradually narrowed behind ; convex, smooth, with a
short impressed line at the middle, four discoidal punctures, forming a quin-
cunx, and four others on each side ; there is also a transverse range of punc-
tures near the base; the two posterior' dorsal punctures are elongated, resem-
bling the short medial line. Elytra convex, wider but not longer than the
thorax, smooth, with a few subsutural punctures, three or four in a short dor-
sal series, and three or four others near the side. Abdomen pubescent, cylin-
drical, not margined, very finely punctulate, pointed at the tip, one-half longer
than the elytra.

DELEASTER Er.

D. concolor, piceo-ferrugineus, pedibus testaceis ; capite laevi, postice
utrinque oblique impresso, vertice convexo, occipite transversim constricto ;
thorace capite vix majore, ovato, basi apiceque truncato, disco subtiliter cana-
liculate postice et utrinque ad latera late excavato ; elytris thorace duplo lati-
oribus, planis rugose punctulatis subopacis. Long. 7-5 mm.

Mr. Ulke received two specimens from San Francisco, California, one of
which he has liberally given to me ; it resembles the European D. dichrous
in size, form and sculpture, but differs by the head and abdomen not being*
darker than the thorax and elytra.

ANTHOPHAGUS Grav.
A. vertical is Say. I found on the shores of Lake Superior two speci-
mens of a variety of this species, in which the body is of a uniform black color,
the legs alone being brownish-testaceous ; a similar specimen occurred in Ly-
coming County, Pennsylvania, on the banks of the Loyalsoc.

LESTEVA Latr.

L. fusconigra Ma'clin, Bull. Mosc, 1853, 193; Phloeopterus fuse. Motsch.

A specimen of this remarkable insect was collected in El Dorado County, Cali-
fornia, and sent me by Dr. J. G. Cooper.

AMPHICHROUM Kraatz.

A. laevicolle, nitidum, thorace ovali, latitudine breviore, angulis valde
rotundatis, disco convexo impunctato, lateribus depressis, elytris thorace duplo
longioribus, haud dense punctatis breviter pubescentibus, abdomine lsevi, bre-
viter pubescente. Long. 3-75 — 5 mm.

Mas, minor, niger, thorace elytrisque piceis, limbo omni testaceo, ano, anten-
narum basi, palpis pedibusque flavo-testaceis.

Femina, major, rufo-testacea, capite nigro-piceo.

I found this species abundant on the flowers of Cratwgus tomentosa, in Lyco-
ming County, Pennsylvania. It is closely allied to the California A. f 1 o r i-
bundu m Lee, but differs by the thorax being more distinctly transverse, the
hind angles more rounded, and the disc free from punctures. The antenna-
are a little shorter and less slender.

Specimens of the male occur in which the elytra are entirely testaceous, but
in general the disc is piceous, with the entire margin (including the suture) of
each pale.

PROGNATHA Latr.

P. punctata, castanco-fusca, nitida, capite thoraceque punctatis, elytris
thorace longioribus, crebre striatim punctatis, abdomine parce punctulato, pe-
dibus ferrugineis. Long. 4-3 — 6 mm.

Pennsylvania, Mr. Ulke ; Canada, Mr. Saunders. This species differs from
P. am eric an a by its dark color and much stronger punctures. In well
developed males the mandibles ascend in the form of a slender curved horn,
and the supra-antennal horns are long and straight, converging but slightly.
The elytra are free from the numerous short longitudinal lines seen in P. c o n-
v e r g e n s, and are tolerably strongly striate and punctured.

LISPINUS Er.

L. 1 a? v i c a u d a , minus elongatus convexus, piceo-niger nitidus, capite
parce punctulato, thorace elytrisque subtiliter parce punctatis, illo versus an-
gulos posticos fovea parva impresso, abdomine vix punctulato, segmentis piceo-
marginatis, ano dilutiore ; subtus piceus, antennis palpis pedibusque piceo-
ferrugineis. Long. 3-4 mm.

Illinois, Mr. Ulke. This species is less slender than the others in my collec-
tion, and is easily distinguished by the characters above given. The exposed
portion of the abdomen is not much longer than the elytra ; the latter are con-
vex, finely but not densely punctured, with the sutural stria deeply impressed.

MURMIDIUS Leach.

M. depressus, rotundato-ovalis, parum convexus, testaceus subnitidus,
subtiliter pubescens, thorace latitudine fere triplo breviore, lateribus rotun-
datis, antice fortiter angustato, disco aequaliter parum convexo, elytris seriatim
punctatis. Long. 1 mm.

This species has an extensive range in the Northern States. I have seen
specimens from Pennsylvania, District of Columbia, and Ohio. Of its habits I
know nothing.

Another species, of which I have received two specimens, collected by Dr.
Brendel, in Florida, agrees perfectly with the figure of M. o v a 1 i s in DuVal's
work, and with the description of Ceutocerus advena Germ. Ins. nov. p. 85. It
is quite distinct from M. depressus by the larger size (1-5 mm.), oval
convex form, shining lustre, less obvious pubescence, and by the sides of the
thorax being distinctly impressed, especially towards the anterior margin,
where just inwards from the antennal cavity may be seen a broad fovea. Ger-
mar expresses a suspicion that his species is different from Hister o v a 1 i s
Beck., but there is nothing in any of the works before me to warrant the belief
that two distinct species have been recognized by any European entomologist.

AMPHOTIS Er.

A. U 1 k e i, elliptica, depressa, brumneo-picea, fere opaca, pube brevi de-
pressa parce vestita, thorace confertim punctato, lateribus piceo-rufis subdia-
phanis, late depressis, angulis posticis subobtusis, hand rotundatis ; elytris
margine late explanato, guttis nonnullis pone basin alterisque fasciam denta-
lam pone medium formantibus piceo-rufis; sutura, costisque utrinque 5 paulo
elevatis breviter setosis, interstitiis sub-3-seriatini punctatis, lateribus fortiter.
margine depresso disperse punctatis ; subtus punctata, picea, pedibus piceo-
rufis. Long. 7-5 mm.

Washington, D. C, two specimens found by Mr. Ulke ; Massachusetts, Mr.
Sanborn. Differs from the species of L o b i op a (to which this genus is nearly-
allied) not only by the less setose upper surface, but by the costate elytra ;
there is a series of large punctures between the convex surface of the elytra
and the depressed less coarsely punctured lateral margin The mentum,
though bisinuate in front, has the exterior angles more prolonged than in the
other species of the genus, so that it appears broadly eniarginate.

[Dec.

NATURAL SCIENCES OF PHILADELPHIA. 377

Differs from the European A. marginata by its larger size and narrower
form.

On examining a specimen of Lobiopa guttulata Lee, given me by Mr. B.
Billings, of Ottawa, C. W., I find that the antennal grooves are slightly conver-
gent, and do not follow the contour of the eyes as in Lobiopa undulata and
setulosa: it therefore appears to belong properly to Soronia Er. The tarsi
in both genera are narrow.

CYLLODES Er.

C. biplagiatus, rotundatus convexus, niger nitidus, subtiliter puncta-
tus, elytris plaga magna subbasali rotundata rufa ornatis, punctis paulo majo-
ribus striatim positis ; pygidio nudo ; antennis rufo-testaceis, clava fusca.
Long. 5 mm.

Two specimens were found on Mount Holyoke, Massachusetts, by Mr. Geo.
D. Smith, who has liberally placed one of them in my collection. This species
differs from the European Cater by the large red spot on each elytron near
the base.

The genus C y 1 1 o d e s is to be distinguished from the genera of Cychramini,
defined on p. 84 of my Classification Col. N. Am., by all the tarsi being di-
lated, and the prosternum produced behind the front coxae, covering the me-
sosternum in repose, and meeting the metasternum, which is somewhat promi-
nent between the middle coxae. The antennal grooves are short, not very well
marked, and converge on the under surface of the head.

PITYOPHAGUS Shuckard.

P. cephalotes, cylindricus, supra piceo-niger nitidus, fortiter punc-
tatus, capite convexo, lateribus pone oculos parvos rectis parallelis, thorace
capite baud latiore, latitudine paulo longiore, lateribus rectis, angulis haud
rotundatis, apice basique late rotuudato, elytris stria suturali impressa, hu-
meris rectis prominulis, lateribus parallelis, apice recte truncatis, pygidio
dense puuetato, concavo ; corpore subtus, antennis pedibusque piceo-ferrugi-
neis. Long. 5-5 mm.

One specimen, Columbia, Pennsylvania. This species resembles in form the
European P. f e r r u g i n e u s, but differs in color. The sixth ventral segment
is quite distinct in the specimen, which is therefore a male.

RHIZOPHAGUS Herbst.

One specimen from New York given me by Mr. Ulke. Larger than the
next, wiih the thorax broader, and the punctures of the striae of the elytra
much more closely placed. This species agrees with the description of the
Russian American R. scalpturatus Mann., Bull. Mosc, 1852, 362, but on
account of the difference in locality it is unsafe at present to regard them as
identical.

One specimen; Arizona, Dr. Coues. Intermediate in size between L. com-
plex and L. pusillus, and quite different from both by the characters
above detailed. The discoidal costae of the thorax are separated by a wide
excavation, as usual, and do not attain either the base or the apex; in front
they are surrounded by a deep impression, limited by a hook-shaped elevated
line, the outer leg of which is a little longer.

L. simplex, valde elongatus, cylindricus, piceus, opacus, pilis parcis

latitudine fere sesqui longiore, lateribus parallelis tenuiter marginatis, angulis
omnibus rotundatis, disco late sulcato, lineis elevatis solitis fere obssletis ;
elytris sutura costisque utrinque quatuor elevatis, interstitiis biseriatim cri-
bratis. Long. 2-5 mm.

One specimen from Cape San Lucas, Lower California; Mr. Xantus. Easily
known by the cylindrical form, and the almost obsolete sculpture of the tho-
rax ; the usual discoidal costae and the hook-formed elevations surrounding
their anterior extremity can be barely traced. The four costae of the elytra
are acutely and equally elevated, and the intervals each marked with two
rows of quadrate punctures.

Arizona, Dr. Coues. This species is as elongate as Au. tuberculatum,

but has only two thoracic tubercles, which are less elevated than in Au.
pa rallelopi pedum, though more distinct than in Au. ae q u i c o 1 1 e.
The striae of the elytra are composed of finer punctures than in these spe-
cies, though a little more distinct than in Au. tuberculatum.

SYNCHITA Hellwig.

S. 1 a t i c o 1 1 i s Ditoma latieollis Lee. New spec, p. 66.

The specimen which served as the type of the description had lost the an-
tennae, but so resembled in form, sculpture and coloration, our common D.
quadriguttatum, that I had no hesitation in referring it to the same
genus. I have since obtained a more perfect specimen, and find that the club
of the antennae is solid ; as the antennae are not received in grooves, I have
placed the species in Synchita. An approach to the Ditoma-like sculpture is
seen in S. v a r i e gata Lee, but less decided than in the species in question.

NAUSIBIUS Redt.

N. repandus, linearis, depressus, fusco-piceus, subtiliter pubescens,
capite thoraceque confertim punctatis, illo lateribus baud reflexis, hoc lati-
tudine longiore, lateribus repandis, disco ante basin vix impresso ; elytris
confertim minus subtiliter seriatim punctatis, interstitiis angustis, vix elevatis ;
suhtus fortiter punctatus. Long. 3-5 mm.

Mr. Ulke has found at "Washington, D. C, several specimens of Nausibius
differing from N. d e n t a t u s by the smaller size, narrower form, and much
stronger sculpture; the upper surface of the head is uniformly and slightly
convex, not depressed and reflexed at the sides as in the last named species ;
the sides of the thorax are not toothed in outline ; the anterior angles promi-
nent, rounded, the hind angles acute, with four very feeble undulations be-
tween them. The tooth of the hind thighs is as prominent as in N. d e n t a t u 8.

LATHROPUS Er.

A species of this genus has bpen found abundantly by Mr. Ulke, near
"Washington, D. C, which by description I cannot distinguish from the
European L. sepicola, except that the alternate intervals of the elytra are
scarcely more elevated.

I fouud several specimens at Fort Yuma, California, differing from those
given me by Mr. Ulke in being brown instead of black, the sides of the
thorax somewhat more rounded, and more distinctly repand, and the alternate
intervals of the elytra distinctly more elevated.

I am not prepared at present to discuss the value of these differences, and
therefore confine myself to making known the existence of the genus in North
America.

Trogosita pusillima Mann., Bull. Mosc, 1843, p. 303, from Sitka, is
probably a species of Lathropus, but must differ, according to description,
by the thorax having a dorsal impressed line in addition to the lateral
ones.

LiEMOPHLCEUS Lap.

L. angustulus, linearis, subdepressus, testaceus, subtiliter pubes-
cens, capite thoraceque confertim punctatis, hoc latitudine fere sesqui longiore,

Washington, D. C. ; Mr. Ulke. Narrower than our other species, approach-
ing in form a Silvanus. The thorax is nearly one-half longer than wide,
tolerably densely and strongly punctured ; it is slightly narrowed behind the
middle, and the angles are rectangular ; the lateral stria is well marked, and
the disc is marked with a vague longitudinal impression.

This species belongs to the division with the scutellum transverse, and
the front very slightly emarginate, and represents in North America L. clema-
tidis of Europe.

ELMIS Latr.

In the mountain region of Pennsylvania; Mr. Ulke. This and the next
species belong to the second group of Eiichson (Ins. Deutschl., iii. 527), not
before known to be represented in our fauna. The characters above given
easily distinguish it from the European species described in his work. The
punctures of the striae of the elytra are but little larger, though less distant
than those of the intervals.

E. nitidulus, oblongo-ovalis, angustior, convexus, niger supra nitidus,

motis seriatim positis, stria 4ta profunda, interstitiis uniseriatim punctulatis,
lateribus subcarinatis ; antennis pedibusque rufis. Long. l-25 mm.

New York; Mr. Ulke. Smaller and narrower than the preceding, and
easily recognized by the different sculpture of the elytra. The punctures
representing striae are large and distant ; the fourth stria is deeply impressed,
so that the fourth interval is slightly elevated. The scutellum is almost or-
bicular in this species ; in E. latiusculus it is somewhat oblong, or oval,
while in our vittate species (E. vittatus, bivittatus and 4-notatus)
it is elongate and triangular. I also observe that the base of the
prothorax is feebly emarginate in front of the scutellum in E. latiusculus,
though much less so than in Limnius oval is and fastiditus. In L.
el eg ans, the scutellum is oval rather than orbicular, and in the List I have
placed that species in Elmis ; but it would be preferable to adopt the opinion
of Lacordaire, (Gen. Col. ii. 509), and regard the differences as not sufficient
to separate the genera.

DORCUS McLeay.

D. co status. In my List of Coleoptera of North America a new species
is mentioned under this name, but, by inadvertence, does not appear
in the Descriptions which accompany that work. On examining the single
female upon which I proposed to found the species, I am rather dis-
posed to regard it as an extreme variation of D. p a r a 1 1 e 1 u s. It agrees,
in form, size and sculpture, with that species, except as regards the elytra,
which are not deeply striate with convex intervals, but have the suture and
four narrow costae on each, elevated, shining and punctured ; the broad
spaces between these costae, and the whole of the apex, are deeply and densely
punctured. On close examination I perceive here and there faint remnants
of striae in the broad punctured spaces, and the difference in sculpture, so
striking at the first view, may be regarded as produced by the suppression of
some of the convex intervals between the striae of D. parallel us, the
suture, the third, sixth, ninth and outermost ones only being left. The spe-
cimen was found in western New York.

NATURAL SCIENCES OF PHILADELPHIA. 381

Fort Whipple, Arizona, Dr. E. Coues, U. S. A. This species resembles, in
size and color, C. cyanellus Lee, but is more oval in form, and differs
by the surface being free from punctures, and by the form of the clypeus,
which in C. cyanellus is four-toothed, with the margin scarcely refiexed,
while in the present species it is formed as in C. lsevis. The eyes are
narrow ; the margin of the thorax is scarcely interrupted on the under sur-
face near the anterior angles, the tubercle seen in most species being nearly
effaced, though not absolutely wanting, as in C. cyanellus, simplex
and some otliers.

C. puncticollis, rotundato-ovatus, antice convexus, ater opacus, sub-
tiliter reticulatus, clypeo obtuse 6-denlato, margine reflexo, capite parce punc-

lis vix elevatis parcis obsitis. Long. U — 7 mm.

Two specimens, Cape San Lucas, Lower California, Mr. Xantus. This spe-
cies has the appearance of small specimens ofC. praticola Lee, and, like
it, has the eyes narrow, and the margin of the prothorax interrupted on the
under surface by a well marked tubercle, 'but differs from it as from all the
other species in my collection, having the last mentioned character, by the dis-
tinct punctulation of the head and thorax. The color is a dull black, as in
C. praticola; each elytron is slightly bituberculate at the base near the
scutellum in both specimens, but more distinctly so in the larger.

Texas, near the Rio Grande, two specimens. This species resembles, in the
armature of the head and thorax, C. moechus and C. anaglypticus,
but differs essentially from them by the clypeus being not incised at the tip,
but armed with two distant small obtuse teeth ; the punctures of the thorax
are larger and unequally distributed, the greater portion of the surface being
smooth; the medial tube»cles are distant, and not united ; the intervals
between the striae are smooth and convex, the strife themselves very fine, and
marked each with a row of punctures extending transversely.

GEOTRUPES Latr.

I have mentioned in the List, under the MS. name G. retnsns McLeay,
a remarkable species found, in the Southern States, underdecomposing fungi.
It is not described in the monograph of Geotrupes by Mr. Jekel,* and, in
fact, constitutes a group distinct from any of those characterized by him.

The elytra are broadly ovate, very convex, connate and destitute of strise ;
the clypeus is semicircular, with the lobes before the eyes large and rounded ;
the front in the r^ is armed with a shorthorn or acute tubercle, whicli in the
9 is reduced to a feeble elevation ; the prothorax of the $ is flattened and
declivous before the middle, and longitudinally broadly excavated, thus pro-
ducing a transverse somewhat lunate elevation about the middle ; in the
female a slight dorsal channel is seen, and a feebly-impressed fovea each side,
half way between the middle and the lateral fovea. The apical tooth of the
anterior tibia? of the ^ is broadly emarginate at tip, and prolonged inwards
into a slender acute process. The middle tarsi of tf are slightly larger than

upper surface is opaque and very densely granulated ; the second joint of the
antennal club is normal, that is, not received in the first. If a name for this
group is considered desirable, it may be called Mycotrupes.

One male, Arizona, Dr. Coues, U. S. A. This species has an elongate form,
being somewhat similar in size and form to Chalepus trachypygus. The color
above is dark brown, the sides of the thorax and two short vittse on each elytron
are pale yellow ; the scutellum is pale yellow, margined behind with brown ;
the head is moderately punctured, the clypeus parabolic and very narrowly
margined ; the palpi and antenna? are brown, the latter have but nine joints,
, the sixth being thicker but not longer than the third ; the club is a little
longer than the joints 2, — 7 together, but does not present the elongate form
seen in the males of our other species ; the thorax is twice as wide as long,
gradually narrowed in front, rounded on the sides, finely and sparsely punc-
tured, sides pale, with a large brown cloud connected with the ground color of
the disc ; elytra sparsely punctured, punctures finer towards the tip ; a faint
trace of a discoidal elevated stripe may be seen, outside of which are two
parallel pale yellow vittse occupying the middle third of the length ; pygidium
and pectus testaceous, hairy ; abdomen brown ; the last segment and hind
margin of penultimate yellow ; feet testaceous ; trochanters, knees, margin
of tibise and tarsi brown.

NATURAL SCIENCES OF PHILADELPHIA. 383

This species resembles in form S. s pi e n d e n s, and, like it, presents
no great sexual differences. It differs from that, as from all other
species of the genus known to me, by the mandibles being broadly
truncate at tip, with the outer angle rounded. I may remark, in passing,
that the ^ of S. splendens resembles very much the 9 of S. J u 1 i a n u s,
but may be easily distinguished by the form of the clypeus, which in the
latter is more acute and subtruncate at tip, while in the former it is less
acute, and more rounded. The excavation of the prothorax likewise retains
iu the $ of S. Julianus a subtriangular form, while in S. splendens
it is quite circular.

PHILEURUS Latr.

P. ill at us Lee. On renewed examination of the fragments upon which
I established this species, with specimens of P. v i t u 1 u s Lee, N. Sp. p. SO.
from Cape San Lucas, I am convinced that they are identical ; the latter
name should therefore be suppressed. The species is common to the region
of the Colorado Desert, and Lower California, and is another example of the
propriety of including the latter province within the zoological, as it will
eventually be within the political, boundaries of the United States.

ANCYLOCHIRA Esch.

In my revision of the Buprestida? of the United States, I have divided the
species of this genus into two groups. The first contains those in which the
anterior tibise are emarginate internally in the male, and hooked at the ex-
tremity ; the last three dorsal segments of both sexes are rounded ; the fifth
ventral segment varies in form, according to sex ; the thorax is sometimes
subcarinate, but never channeled. The second contains the species having
the tibife alike in both sexes ; the antepenultimate dorsal segment is trun- '
cate or emarginate ; and the fifth ventral is alike in both sexes, broadly trun-
cate, with the angles slightly prolonged ; the thorax is always feebly chan-
nelled. A. sexplagiata, Langii and fasciata, which, in the List,
are placed in the first division, should be transferred to the second.

ACMiEODERA Esch.

A. amplicollis, robusta cuneiformis, senea, vel cyaneo-senea, punc-
tata, supra pube longa erecta villosa, subtus laxe ciiiereo-pubescens, thorace

punctulatis. Long. 10—12 mm.

Fort Whipple, Arizona, Dr. Cones. At first sight this species resembles
the Texan A. semivittata Lee, but it differs very much in the form of
the thorax, by the elytra being narrowed behind from the base, and by the
striae being formed of very coarse punctures. It resembles, in the form of the
thorax, A. flavomarginata and opacula, but is more robust than
those species ; as in them the last ventral segment has an acute submarginal
crest around the tip.

One specimen, Arizona, Dr. Coues. This species resembles A. variegata
in the marking of the elytra, and general form of the body, but differs
essentially in the form and excavations of the thorax ; the sides are consider-
ably rounded, less oblique than in A. c o n n e x a, less suddenly and less
strongly incurved at the hind angles ; the transverse submarginal crest of the
last ventral segment is very short, almost as in A. o rna ta.

One specimen, Arizona. It gives me pleasure to commemorate the valued
labors of Dr. Coues in Arizona by dedicating to him this beautiful species. It
is of a more tropical form than any other in my collection, and is easily recog-
nized by the characters given above ; the two spots in ths elytral sulcus unite
the elevated suture and the discoidal costa ; one is at the end of the latter, and
the other a little anterior. The scutellum is of the usual form, but is deeply
excavated and punctured in the middle, and not transversely carinate ; the
ungues are armed with a large tooth, which is not acute at tip. This species
is to be placed as a distinct group, before A. bilineatus. (Vide Lee. Trans.

One specimen, Peoiia, Illinois; collected by Dr. E. Brendel and communi-
cated to me by Mr. H Ulke.

This new genus has the general form and sculpture of Anthaxia, but differs
from that as from all other Buprestidse by the antennae being pec'inate.

Body elongate, dull black, with a brassy tinge ; head and thorax sculptured
with shallow reticulations (as in Anthaxia); the former convex, with a broad
medial furrow; antennae longer than head and thorax, black, 11-jointed, first
joint obconical, second and following about equal in length, produced exter-
nally into a long process, which is near the base in the second joint, but gra-
dually changes its position until it becomes apical in the tenth joint ; eleventh
joint similar in length and form to the ramus of the tenth joint. Thorax
quadrate, wider than its length, with the angles acute ; slightly convex,

NATURAL SCIENCES OF PHILADELPHIA. 385

sculptured as the head, slightly channeled, and marked with a strong trans-
verse impression just before the middle; apical and basal margins bisinuate-
sides slightly rounded in front andsubsinuate behind. Elytra rough with ele-
vated points, sides serrate, more distinctly toward the tips, which are sepa
rately lounded ; broadly impressed each side at the base, and ornamente I
with a large pale spot, which extends nearly one-third the length, ani lades
insensibly into the black ground color.

Body beneath black, somewhat shiuing, under surface of prothorax reticu-
late, of trunk granulate like the upper surface. Feet piceous, hind tarsi with
the first joint as long as the others united, third and fourth joint with short
membranous lobes ; ungues simple.

The antenna? are inserted under small oblique ridges, the front is not dilated.
The mentum is broad, transverse, and apparently rounded in front. The pro-
sternum behind the coxa? is narrow, not angulated on the sides, acute at tip ;
the mesosternum is completely divided, and is not connate with the metaster-
uum ; the side pieces of the latter are moderately broad, the epiraera not cov-
ered by the abdomen, and the sternum itself is marked each side with a large
hairy depression. The hind coxa? are broad, scarcely narrowed externally,
and extend not quite to the side of the abdomen. The last ventral segment
is emarginate.

I consider this genus as representing a new group of the tribe Buprestini
(Lee. Class. Col. 151), between Buprestes and Anthaxia?.

liter cinereo pubescentibus ; subtus confertim punctata, pube alba dense ves-
tita, antennis pedibusque la?te rufo testaceis. Long. 14 mm.

One female from California, presented to me by Andrew Murray, Esq. This
new genus is founded upon an insect of rather stout form, having the elytra a
little wider than the thorax, parallel and finely margined on the sides, round-
ed and not serrate at tip ; having the claws armed with a large but not very
acute tooth, and the membranous appendage of the fourth tarsal joint deeply
divided into two narrow lobes, as in Schizopus.

The head is short and convex, the antenna? inserted under very slight fron-
tal ridges, and are feebly serrate in the female; the joints 1—4 are smooth
and shining, the following ones slightly porous, and feebly pubescent on the
sides. The eyes are transverse, elliptical, moderate in size, and finely granu-
lated. The labrum is small and deeply emarginate ; the mandibles are short
and very stout ; palpi broken. The thorax is trapezoidal, sides straight, with
the lateral margin well marked behind the middle ; base broadly Insinuate,
hind angles acute ; scutellum transverse, acute at tip. Elytra destitute of
striae, each broadly rounded at the base, fitting closely the basal outline of the
thorax ; wider than the thorax, parallel and finely margined at the sides, ob-
tusely rounded at tip. Prosternum short, slightly produced over the meso-
sternum, obtusely rounded at tip; meS"sternum short, side pieces large, ex-
tending to the coxa? ; metasternum short, posterior outline sinuate, with an
oblique engraved line near the inner half; episterna wide, epimera very small.
Anterior and middle coxa? small; trochantin indistinct or wanting ; hind coxa?
extending nearly to the side of the abdomen, slightly wider inwards. Legs
slender, femora unarmed, tibia? with small spurs ; tarsi shorter than the tibia?,
joints 1 — 4 with membranous lobes beneath, second lobe slightly emarginate,
third lobe deeply emarginate, fourth lobe bilobed and much longer, claw joint
moderately long, claws armed with a tooth near the tip. Abdomen with fivo
ventral segments, the first and second connate, the fifth rounded at tip.

386 PROCEEDINGS OF THE ACADEMY OP

A careful comparison of this singular insect with Schizopus laet us Lee,
(figured in Thomson's Arcana Naturae pi. xiii. f. 4), shows that, apart from
the form and number of the last ventral segments, and the less strongly ser-
rate antennae, which are sexual characters, the two genera differ very slightly ;
the side margin of the thorax is indistinct, even towards the base in Schizopus,
and the sides themselves are somewhat curved ; the scutellum is less trans-
verse, the punctuation of the upper surface is coarser, and the pubescence of
the under surface less dense ; the membranous lobes of the first, second and
third tarsal joints are much less developed ; and the labrum is somewhat
larger, though also emarginate. On comparing D y s t a x i a with an ordinary
Buprestide (one of the second division of An cy lo chira for instance}, there is
seen to be almost no difference in the head, except that the mandibles are
thicker and more obtuse, as many other genera of Buprestidae ; the prosternum
fits less accurately to the mesosternum ; the trochantins of the front and
middle cox.-e are less distinct, and the hind coxae are less dilated inwards. All
these are characters of feeble importance, and the only really well marked
distinctions, of more than generic value, consist in the divided membranous
tarsal lobes, and the toothed ungues. The last character is seen in several
genera of Buprestidae, and the former is certainly insufficient for more than a
secondary division of the family.

I therefore conclude that the family Scbizopodida? must be suppressed, and
that Schizopus and Dystaxia must be associated as a separate tribe, which
may be placed after Buprestini, under the name Schizopini, and characterized
by the lobe of the fourth tarsal joint being cleft.

STETHON Lee. (n. g. Eucnemidae).

S. pectorosus, cylindricus, antice paulo latior, piceus haud nitidus,
supra confertim punctatus, brevissime pubescens, capite magno, fronte obso-
lete canaliculata, thorace latitudine vix breviore utrinque obsolete bifoveato, et
pone medium obsolete canaliculato; elytris striatis, autennis, palpis pedibusque
ob?cure rufis. Long. 8 mm.

Two specimens of this species were found by Mr. M. Schuster, in central
Illinois, one of which he has kindly placed in my collection.

This genus is readily distinguished by the following characters : Head
large, eyes not touching the anterior margin of the prothorax; epistoma broad,
emarginate each side for the reception of the antennae, which are distant,
11 jointed ; first joint long, as usual, second very short, third twice as long as
wide, 4 — 10 quadrate, gradually shorter, more transverse, and slightly
narrowed inwards, eleventh rounded at tip, one-half longer than the preceding.
Maxillary palpi compressed, last joint securiform. Prothorax with a deep
channel beneath the lateral margin, for the reception of the antennae, this
chaunel sharply terminated under the hind angles ; side pieces excavated be-
hind for the reception of the anterior legs ; prosternum very broad, strongly
margined in front, lateral sutures much curved, convex outwards, not exca-
vated, posterior process broad, acuminate at tip. Metasternum with the side
pieces very narrow ; hind coxae broad, somewhat dilated internally, and ob-
tusely angulated. Last ventral segment obtusely acuminate at tip. Legs
short, tarsi not lobed beneath, first joint as long as the four following united,"
claws not toothed.

It resembles Otho (known to me only by figure and description), but
differs by the third joint of the antennas being longer than the fourth, by the
antennae being less approximate and not pectinate, and by the form of the hind
coxae. I infer also that the sutures of the presternum are different in direc-
tion, since such an important character would not have been overlooked in
the description of the European genus. It has also strong relations with
D en droc h aris, from which it differs by the non pectinate antennae, and
simple tarsi, as well as by the epistoma being distinctly emarginate for the
. insertion of the antennae, and by the eyes not touching the prothorax.

species is more robust than F. cy lin dr icoll is, to which it bears resem-
blance on account of the sculpture and thoracic impression, but it differs by
the grooves for the reception of the antennae being feeble, and ill defined, and
by the fourth tarsal joint being not at all dilated. It agrees with F. c y 1 i n-
dricollis in having the third antennal joint twice as long as the fourth,
and in the ungues being not toothed.

F. calceatus belongs to the genus Dromseolus Kies., which, as ap-

form Eucnemis amoenicornis, but is readily distinguished both by the
generic and specific characters.

The antenna? are about half the length of the body ; the first joint is rather
stout, and reaches to the hind margin of the eyes, the second is small, the
third about one-third longer than the fourth ; the joints 4 — 10 gradually in-
crease slightly in length and thickness, and the eleventh is longer than the
ninth and tenth united, parallel on the sides, and obtusely rounded at tip ;
the inflexed portion of the prothorax is broadly but distinctly concave, midway
between the prosternal suture and the side margin, for the reception of the
basal portion of the antennae ; the prosternal sutures are deep, and the poste-
rior spine rather broad. The hind coxae are gradually but strongly dilated
inwards, and broadly truncate behind, almost exactly as in Euc. amoenicor
n i s. First joint of middle and hind tarsi as long as the others united ; fourth
joint not dilated, claws small, simple.

The fine carina of the head extends from between the antennas to the occi-
put, and might, without careful observation, be regarded as an impressed
line.

Eucnemis frontosus Say seems to be better placed in this genus tban in
Nematodes, to which, in the List, I have referred it. The first joint of the
antenna? is much stouter than in N. atropos and penetrans; the in-
flexed portion of the prothorax is wider, and the prosternal spine is broader
and more obtuse.

appearance Agriotes oblongicollis. This species differs from those pre-

that the hind angles are much less obvious ; the third joint of the antenna? is
also quite different in form, being triangular, with the outer angle obtusely
and slightly produced ; the fourth and fifth joints are produced at the middle
of the outer margin into obtuse processes ; the processes of the outer
joints originate near the base of each joint; in C. pulsator all the
processes originate at the base of their respective joints, and the third joint is
not different in form from the fourth. The tibia? and tarsi are tinged with
ferruginous.

the European A. le p ido pter a, as given by Candcze (Elat. i. 52), except
that there is no impression each side of the dorsal channel of the thorax.

13 mm.

One specimen found near Philadelphia, by J. Johnson Brown, Esq., and
another at Washington, D. C, by Mr. Ulke. Related to A. a vita, but differs
by the pale scales not being uniformly diffused, but aggregated into spots.
The thorax is scarcely channeled, and is ornamented with four discoidal
patches of pale golden scales ; the sides, and to a less extent the apex, are
sprinkled with similar scales. The elytra are slightly depressed towards the
suture, and are feebly striate towards the base and sides ; there are small
scattered patches of pale golden scales, and two spots placed near the sides at
three-fourths of the length of the elytra, forming an oblique sinuous short
fascia; another spot is seen on the side near the apex. The front is not con-
cave ; the antennae are fuscous, and extend to about the middle of the thorax.
The feet are fuscous, and the tarsal grooves of the under surface of the pro-
thorax are distinct, though not well defined. The under surface of the body
is uniformly though not densely clothed with pale scales.

Specimens which agree with the descriptions of this European species were

only the humeral spot of the elytra is present. The resemblance in form to a
small Cardiophorus, mentioned by Candeze, is very striking.

extends from the humerus backwards, about one-third the length of the ely-
tron, growing broader posteriorly, and inclining towards the suture ; the pos-
terior spot is transverse, reaching neither the suture nor the side, and is placed
about the posterior third of the length.

In form this species is similar to C. c h o r i s, from which it differs altogether
by its sculpture.

One specimen from Maryland, in the collection of Mr. Ulke. Very distinct
by the punctuation of the thorax, which is coarse near the anterior margin,
gradually becoming fine and very dense at the base. The head is coarsely
punctured, the front somewhat flattened and vaguely impressed ; the thorax
is feebly channeled behind the middle. The third joint of the antennae is
about twice as long as the second, and but little shorter than the fourth.

Rock Island, Illinois ; Mr. B. D. Walsh. The disc of the thorax is mode-
rately convex, very feebly channeled, covered (except near the apical margin
which is moderately punctured) with a very fine punctuation, so dense as to
make the surface dull ; the pubescence is short and erect. The front is
slightly depressed ; the third joint of the antennae is not dilated, and is one-
half longer than the second. This species is very distinct by the sculpture of
the thorax.

The female differs by the thorax being more convex and less narrowed in
front. The antennae are alike in both sexes.

Fort Simpson, Hudson Bay Territory. This species is quite different from
any other in my collection, and seems, by description, to be related to the
European L. cylindricus. As in that speeies, the carina of the hind
angles of the thorax is very near the side margin, and the prosternum is
feebly channeled between the front coxae. Tbe prosternal sutures are deeply
excavated anteriorly, and the yellow color of the under surface of the front
angles extends along the prosternal sutures half way to the front coxae.

L. infernus. Specimens of this species, labelled Elater nimbat us
Say, are contained in the collection of Dr. Melsheimer, now belonging to the
Museum of Comparative Zoology at Cambridge, Massachusetts. The descrip-
tion of Say does not represent the characters of the species in a recognizable
manner, but, as his specimen was obtained from the elder Melsheimer, there
can be no doubt of tbe authenticity of the specimens now in the collection.

A badly preserved specimen from Montana Territory is in my collection. It
resembles in appearance A. equestris, but is smaller, and the elytra are
shining, and finely punctured, while in that species they are opaque, and
coarsely scabro-punctate. The base of the elytra is bright rufous, but the
marking is irregular, and may therefore be not constant ; the tarsi are want-
ing, but from the other specific characters I have no doubt that they are lobed
as in A. equestris.

Texas ; sent to me by Mr. A. Salle. Tbis remarkable species does not
resemble any other seen by me, but I have found no characters to warrant me
in separating it as a distinct genus. The body is elongate, not convex, shining
black above, and almost glabrous. The head is punctured and the front is
broadly concave, or rather excavated ; the antennae are longer than the head
and thorax : the second joint small, the third equal to the fourth, triangular
compressed, following joints gradually a little narrower, eleventh distinctly
divided, terminal portion a little shorter. Thorax trapezoidal, sides straight,
strongly margined; hind angles divergent, not carinated; di^c only slightly
convex, tolerably thickly punctured. Elytra as wide as the thorax at the
hind angles, lateral margin strongly refiexed, disc finely punctured, with not
very obvious striae composed of somewhat larger punctures. Hind coxae vevy
narrow externally, gradually somewhat widely dilated inwards (about as in
C. aethiops). Front tibiae compressed, longitudinally concave on the

Specimens of this species from Montana have been subsequently described
by Mr. Bland, under the name C. brunnipes (Proc. Ent. Soc. Phil. iii. 67).

It occurs at Pembina, and various other places in Hudson Bay Territory,
and also in Montana and the interior of Oregon and Washington Territory.

One specimen from Nevada in Mr. Ulke's collection. The abdomen has
seven ventral segments, the five seen ordinarily in Elateridse being increased
by the first, (usually concealed behind the coxae, ) becoming visible, and by the
addition of an apical segment as in the 9 °f Euthysanius (Proc. Acad. Nat.
Sc. Phil. 1859, 74). In the latter, however, the number of visible segments
is eight.

The wings are well developed, and folded under the elytra, which are only
one-half the length of the abdomen.

Corresponding with the female above described is a male in Mr. Ulke's col-
lection, from Fort Tejon, California. The sculpture is the same; the eyes are
large and prominent ; the antenna? are longer than the head and thorax,
strongly serrate, with the external angle of the joints 2 — 10 acute ; the third
joint is similar to the fourth, though smaller. The elytra are as long as the
abdomen, somewhat dehiscent behind, and acute at tip, paler in color than the
head and thorax. The abdomen has six visible ventral segments, the last be-
ing provided with lateral pieces, as in the males of the allied genera. Length
13-5 mill.

I regard this as the male of the Nevada species, and, as indicating a new
genus, differing from Aplastus by the (usual) 5th ventral segment being
truncate at tip in both sexes, fully exposing the sixth segment; the fifth seg-
ment in Aplastus is rounded at tip, and the sixth retracted.

The two specimens of Aplastus optatus in my collection differ greatly in the
form of the antennae ; the one from Mr. A. Murray has the joints 4 — 10 more
strongly triangular, and more produced at the outer angle, than the specimen
found at Bodega (Cal.) by Mr. George Davidson. I was therefore induced to
regard the latter as a female, a view that is confirmed by the different struc-
ture of the last ventral segment in the two individuals ; the lateral valves,
quite conspicuous in the male, are absent in the supposed female.

The tribe Plastocerini thus exhibits in Western America a very beautiful
series of gradations from Aplastus, in whi h the sexual differences are slight,
through Ananiesus, where the elytra are shortened, and the ventral segments
increased in number, to Euthysanius, in which the ventral segments are still
farther increased, the abdomen excessively elongated, the elytra very short,
and the wings wanting. The female of Plastocerus is not yet discovered. A
correspondence with this regular degradation is seen in the form of antennae,
serrate in Aplastus, and Anamesus ; not greatly unequal in the sexes of the
former, much shorter in the female of the latter ; pectinate, with long
branches in males of Plastocerus and Euthysanius, 11-jointed in the former,
12-joiuted in the latter.

Pa. It gives me much pleasure in dedicating it to the Hon. B. F. Patton, to
commemorate his value as a friend, as well as his great interest in the object
of the journey during which the specimens were collected.

It resembles in form P. laevicollis, but may be distinguished from the
variety of that species with yellow thorax by the punctures of the head being
less fine and less dense, and by the rugosities of the elytra being more
obvious ; the thorax is a little broader, the outline of the sides is not concave,
but slightly convex, and the lateral margin is very distinctly depressed and
slightly reflexed ; the antennae and feet are black, tlie first and second joints
of the former are pale beneath ; the palpi are pale, with the tip black. P.
simplex Couper, Canadian Nat., 1865, (52, is also related, but the thorax
is comparatively smaller and less polished, and the base of antennae, the
mouth and the feet are yellow.

Descriptions of some new CICINDELID.ffi from the Pacific Coast of the

United States.

BY GEO. H. HORN, M. D.

The insects described in the present paper form part of a collection brought
by myself from the west coast, accumulated during a four years' residence in
California and the adjoining territories. Believing it important to make known
the existence of these species, the descriptions are here given in advance of a
more extended memoir on the Coleoptera of the Pacific slope of our country.

This species differs from all the others of the genus in being almost entirely'
smooth and subopaque. The elytra are regularly oval, as in californicus, ex-
hibiting a few almost obsolete punctures irregularly placed like the foveas in

dejeanii and the larger punctures of the other two species. The whole surface
is very finely granulate, causing the subopaque appearance. For this species
I am indebted to C. F. Hoffman, Topographer of the Geological Survey of
California, who discovered it while exploring the high Sierras near the head
waters of King's and Tule" rivers. Two specimens, both males, were found.
It is to be hoped that further collections maybe made in this region, as all the
species collected were either new, or served to illustrate the descent of Arctic-
species. Omus audouinii has been found in the high ridges of the Coast Moun-
tain, near Santa Cruz, and californicus has been sent me from the same region
by Dr. J. G. Cooper. Doubtless many interesting discoveries will yet be made
iu the high mountain region^ of California and Oregon.

Related more closely to generosa, though much smaller than any
of the species of that group. The form is rather robust, the sides of
the elytra well rounded, with the apex scarcely serrate. The mark-
ings are rather broad. The middle fascia enters at a right angle to
the margin, bends rectangularly, the longitudinal portion being
longer. Color above black, almost entirely devoid of any metallic
lustre.

I obtained this species while in San Francisco, of M. Lorquin, from a large
box of insects said to have been collected in California. I bave, however, no
doubt as to the truth of the locality, as all the other species were undoubtedly
Californian ; but as some doubt always obtains when specimens are not actu-
ally obtained in their native regions, I have thought it advisable to state the
facts, that the locality of the species might hereafter be verified.
Two specimens are in my cabinet, both males.

Fort Klamath, Oregon. The relationship of this species is evi-
dently with oregona and its allies, differing in its more elongate form
and the absence of the serrulations usually found in the tips of the
elytra in the species of this group. The lunules are both interrupted.
The extension of the humeral being oblique. The transverse portion
of the middle band is at a right angle to the margin, and the longitu-
dinal portion oblique. The labrum is distinctly tridentato, the front
covered with rather long erect hairs. The color is bright green.

For this species I am indebted to Dr. H. M. Cronkbite, Act. Assist. Surg.
U. S. A., by whom many valuable species were collected during his residence
in Oregon and California.

In the accompanying wood-cut the engraver accidentally cut away the sub-
apical spot. It is very small, however, and situated between the apex of the
apical lunule and the end of the middle fascia, being rather nearer the former.

This is one of the prettiest and the most singular of any of the
species yet reported from California. With evident relations with
group xii. (Lee. Revis. Cicind. of U. S.), it possesses characters
rendering it advisable to form a separate group for its reception,
the position of which is in immediate succession to that contain-
ing salt marsh and fluviatile species. The following characters
will serve to define it.
Thorax subcylindrical, sides rounded, posterior angles not produced in
either sex. The form is slightly depressed. The elytra of the female are
broader than in the male, with the tips narrowing obliquely. The markings
are narrow, united along the margin. There is no basal spot. The apical
lunule is prolonged anteriorly. The middle band curves toward the base, and
is suddenly bent at an acute angle, and obliquely prolonged toward the suture
and to near the apical lunule. The body beneath (except pectus and middle
of abdomen) densely clothed with white hair. Labrum is unidentate. Palpi
pale, with dark tips. Legs long, slender, trochanters and tip of abdomen
reddish.

This species is not uncommon on the salt marsh near Wilmington (San
Pedro), California. They fly rather poorly, and hide when pursued in the
short grass. They occurred during August. It is to be hoped that further
collections of this species may be made, as the greater number collected by
myself were destroyed by an accident to which all bottles are liable.

I dedicate it with pleasure to my friend Mr. Wm. M. Gabb, of the Geological
Survey of California, in recognition of his many very valuable services as a
collector in regions inaccessible to myself.

Notes on the habits of species previously described.

C. vulturina Lee. A beautiful green variety of this species has been
sent me from northern Arizona. Similar specimens are in the cabinets of Dr.
Le Conte and Mr. Ulke, from Fort Whipple, Arizona, where my specimen was
probably collected.

C. vulgaris Say, is found all over Oregon and California, whence collec-
tions have been sent me. In the Sierras on Kern river a beautiful sericeous
green variety existed rather abundantly.

C. oregona Lee. Six specimens of this species from Oregon form a
beautiful series, from the fully marked to that without any evidence of either
bands or lunules. They are all of a dull green color. For these I am indebted
to Dr. Cronkhite, U. S. A., who was stationed for some time at Fort Klamath,
whence many interesting species have been sent me. Specimens of this spe-
cies have been sent me from the southern Sierras. To this species must be
referred the fragments partially described, but not named, by Dr. J. L. Le

C. duodecim-guttata occurs everywhere in the Pacific regions, ex-
tending into the valleys east of the Sierra Nevada.

C. h y p e r b o r e a Lee. has been sent me by Mr. Wra. M. Gabb,
from the coast range near Santa Cruz. The markings of this spe-
cies vary in their width. The two specimens in my cabinet have
the markings distinct, while two in the cabinet of Dr. Le Conte
have the humeral lunule and the middle fascia so expanded as to
become confluent. I give a figure of the two varieties, with a view
of completing the series of illustrations of our species.

C. pusilla Say was abundant in Owens Valley, in the beds of streams.

C. haemorrhagica Lee. occurred with the last. It is remarkable that
a species hitherto found only on the sea coast at San Diego, should occur so
far inland.

C. imperfecta Lee. has been sent me from Fort Vancouver, Oregon.

C. guttifera Lee. occurred in tolerable abundance at Fort Grant, on the
San Pedro river, Arizona.

Tetracha Carolina Hope occurred rather abundantly at Fort Yuma,
under chips, etc., on the borders of the Colorado. This insect has now been
found at almost every point from the central Atlantic coast of the United
States to Cape St. Lucas, at the southern extremity of Lower California. It is
probably found along the greater extent of western Mexico. For this and
many other species from this interesting region, 1 am indebted to Capt. John
E. Hill, of California.

398 PROCEEDINGS OP THE ACADEMY OF

Honduras, Dr. J. L. Le Conte. This beautiful insect has been for some years
in the Academy's cabinet. I have till the present deferred its description, with
the hope that in some of the many memoirs on the insects of Mexico and the
adjacent regions, its description might be found. The characters above given
render it inadmissible in any of the groups of the true Rutelides, combining the
characters of two groups in a manner rendering it inadmissible in either. The
horizontal labrum and posterior margin to the thorax define it as a true Rute-
lide.

Two groups form this tribe, Pelidnotas and Areodae, characterized mainly
by the absence of the frontal suture. The present genus can enter neither
group, as the presence of the frontal suture excludes it from the former, while
the forked tarsal claws exclude it from the latter, while the form of the mandi-
bles serves to distinguish it from either. By a modification of the characters
of groups of Areodae of Lacordaire, it might enter here to form the analogue of
Macropoides, of the Pelidnotae. I prefer, however, separating it entirely, to
form an intermediate group. With this view the Rutelidse verse may be thus
tabulated :

Epistome not distinct from front Pelidnotae.

Epistome separate from front.

Mandibles tridentate ; outer tarsal claws forked Macropni.

" simple; " " simple Areodae.

In addition to the above characters, it might be mentioned that the front is
twice as broad as long, the eyes large and convex, the epistome much broader
than the front, forming the canthi of the eyes by the posterior angle. The
head is short, being a third broader than long, and is deeply set in the thorax,
causing the eyes to be partially hidden by its anterior angles. The mesosternal
spine is moderate, flattened, and slightly grooved beneath. The large posterior
coxae depress the plane of the metasternum below that of the abdomen. Me-
tasternum truncate posteriorly and vertical. Posterior coxa? separate. The
abdomen forms an abrupt convexity beneath, thus causing the pygidium to
assume a rather more acute form than usual. The pygidium is very convex
from above downwards, and finely granulate, presenting a more rugose appear-
ance than any other portion of the insect. The species resembles our Cotalpa
lanigera in form, being, however, slightly more elongated, though less
elongated than either of the Areodae.

A single specimen, a male, from which the above description has been taken,
exists in the cabinet of the Academy.

BRANCHUS Lee.

obscurus, oval, slightly convex, black and opaque, sparsely covered with
short black erect hair, head very densely and coarsely punctured, front trans-
versely and longitudinally impressed ; thorax one-third broader^ than long,
densely and coarsely punctured, narrowed anteriorly, and emarginate ; sides
broadly rounded, slightly emarginate in front of posterior angles, which are
but slightly produced and rounded ; base rounded at the middle, emarginate
on each side. Thorax above with a median slightly elevated line, and two
fovea: ; on each side of the median line are four slightly oblique elevated ridges,
arranged in anterior and posterior pairs. Elytra subcostate, with densely
placed elevated granulations towards apex indistinctly foveate. Beneath smooth
shining, scarcely punctured.

Long. -55, lat. -30. Nicaragua.

Differs from the other species by its less convex form ; the sides of thorax are
also slightly emarginate before the angles. The elytra have a distinct ridge
continuous with the thoracic margin and extending very nearly to the apex.
The species of this genus may be divided into two groups ; floridanus Lee. has
the thorax very convex, while in woodii Lee. and obscurus Horn the thorax and
elytra are rather depressed.

Antennae more slender and elongate, the ninth joint rather suddenly dilated.
Mentum trapezoidal sides less rounded and less emarginate anteriorly. Gular
peduncle smaller, with the median notch hardly evident. Anterior tibiae
slightly emarginate at apex, outer angle not prolonged externally. Intercoxal
process of abdomen rectangularly truncate.

This genus, indicated but not named by Le Conte (Class. Col. N. Am.), may
be readily distinguished by the preceding characters from Branchus.

broadly emarginate ; sides broadly rounded, at base broadly lobed ; posterior
angles slightly produced ; above with a slight transverse impression termina-
ting in two fovae, and four oblique slightly elevated lines arranged in anterior

This species is much more convex and more regularly oval than any of the
other Branchini. The legs are also more slender, and the insect has the appear-
ance of being able to move with considerable rapidity.

The tribe Branchini presents some difficulties regarding its proper classifica-
tion. The prominent ligula points to some affinity with the Praocini, but as
this organ is undoubtedly retractile, and capable of being protruded, its value
as a means of classifying the tribes of the Asididae seems hardly apparent. The
removal of certain tribes and parts of tribes (Scaurini pars, Blaptini, Fimeliini.
'Molurini pars, Pedinini, Opatrini and Trachyscelini,) this great subfamily
becomes more homogenous and capable of classification. The tribes above
mentioned have the posterior margins of the third and fourth ventral segments
coriaceous, — a character of great value in the subdivision of the family Tene-
brionidae.

The Branchini seem to have closer affinities with the Asidini and Nycteliini.
The prominent emarginate labrum, the contour of the front, and the slightly
channeled tarsi seem to point toward the Asidini, while the broad emarginate
and fissured gular peduncle and the form of the maxillary palpi indicate their
affinity with the Nycteliini. The form of the antennae serves to distinguish it
from both tribes, the eleventh joint being as large as the preceding, depressed,
and rounded at the extremity.

The following table will serve to distinguish the tribes of the subfamily
Asididae, characterized by the presence of a trochantin to the middle coxae, and
the hind margins of the ventral segments entirely corneous :

Head rhomboidal, narrowed behind. 1.

Certain tribes admitted into this subfamily by Lacordaire have been sepa-
rated entirely. The Scaurini and Scotobiini have been separated from Crypto-
glossini, and the genera allied to Eulabis removed from association with Nycto-
poris, and Cerenopus from Cryptoglossa. The Sepidiini have been removed
from the Molurini. The genus Ogcoosoma must probably also be removed
from association with Moluris and Psammodes. The validity of the removal
of certain tribes and groups from the Asididae as received by Lacordaire, appears
to be still further substantiated by an examination of the manner in which
the pores of special sensibility are distributed on the terminal joints of the
antenna?.*

While examing the Nycteliini in the collection of the Academy, I found under
Gyriosomus a species named " multilineatus Melly," which does not belong even
to the subfamily. I can find no reference to such a species, and no genus into
which it may properly be received. The hind margins of the third and fourth
ventral segments are coriaceous. This insect should undoubtedly form a
new genus near Gonopus and Anomalipus, with which it has many points of
resemblance. The following table of the three genera exhibits their relations :

Kpistoma trapezoidal, broadly emarginate Gonopus.

" rounded, triangularly "
Epipleura indistinct, body very convex E ctatocnemis.

" broad, body flattened above and margined../ Anomalipus.

In the genus above indicated the last joint of the antenna; is very small, the
anterior tibiae much more flattened than in Anomalipus, and have the external
apical angle prolonged into a tooth, and a median tooth to both anterior and
middle tibiae. The tooth existing on the posterior edge of the apex of the an-
terior tibiae in Anomalipus is not present in this genus. The prosternum be-
tween the coxae is bisulcate, as in the other genera, and declivous in front and
not lobed as in Gonopus.

The species, for which I retain the name above given, is very robust. Head
broad, moderately coarsely punctured, with a vague impression each side of the
emargination. Thorax one-half broader than long, very convex, densely and
coarsely punctured, narrower in front, broadly emarginate ; sides strongly
rounded, narrowing posteriorly, angles acute, slightly prolonged, base emargi-
nate. Elytra broadly oval, very convex, humeri obtuse, partially covered by
the posterior angles of the thorax, costate, intervals with a less distinct elevated
line, on each side of which is a row of elevated points.

The female is larger and more robust than the male, and the apical tooth of
the tibia broader and more obtuse.

Length -9 inch. " Coquimbo."

* This character, in its application to this family, was first pointed out by Schioedte (Annals
and Magazine of Nat. Hist. Men., 1865, p. 192, note). Its true value is not yet, fully determined,
but from the lew observations made by myself it promises to be, at least, a very useful character
in fixing the relationships of genera, the positions of which are still in some doubt. 1 have but
casually mentioned this character, hoping to have leisure to develop it in its application to our
North American genera at some future day.

thorax not prominent, the posterior rectangular. • Elytra elongated oval, con-
vex, one-half broader at middle than the thorax, base scarcely emarginate, not
broader than the base of thorax, humeri prominent, deeply light striate, and,
with the marginal, deeply punctured ; interstices elevated, scutellar stria short,

Very distinct from the species described from Cape St. Lucas by the charac-
ters above given. The thorax is evenly rounded, the posterior angles rectan-
gular, without being prominent as in gracilis Lee. The base is finely margined
by a line not reaching the angles ; in front of this a slight transverse elevation,
in front of which is an indistinct transverse impression. In the female these
characters are better marked than in the male. The antenna1 are shorter and
much more robust; in the male they equal in length the head and thorax. The
front is deepty notched both in male and female, exposing the connecting
membrane between the epistome and labrum, exhibiting sexual characters
similar to Zophobas. The anterior tibia? of the male are clothed internally
near the tips with a dense, short pubescence. In this species the presternum
is slightly produced behind the coxae, acute. Mesosternum declivous and
broadly channeled.

Between this genus and Zophobas there appear to exist close affinities.

On the Consumption of Force by Plants in overcoming Gravitation.

BY THOMAS MEEHAN.

Every one interested in Horticulture knows how uncertain is the successful
cultivation of the grape in the United States. The vines usually flourish well
for a few years, but in most instances become the prey of numerous diseases
before they attain any very great age.

In remarkable contrast with this general failure is the fact that grape vines
growing over trees are generally healthy and fruitful to a remarkable extent.
Branches from unhealthy vines on trellises, when they can get to ramble over
the twiggy branches of a neighboring tree, resume the health and vigor lost by
the parent or main vine.

These facts have had numerous observers, and are generally admitted. They
have been frequently discussed in Horticultural journals ; but every theory
hitherto brought forward has been refuted. For instance, it has been sug-
gested that the partial shade afforded by the tree benefitted the grape vine ; but
it is as perfect when growing over low bushes, on hot banks, exposed to high
and dry temperatures, as when luxuriating among the shady branches of the
tallest trees. Again, it has been suggested that as the vine is supposed to like
a dry soil the roots of the tree tended to absorb superfluous moisture, and thus
furnished the best conditions for the vine roots ; but healthy vines are found on
trees in impassable swamps : besides, the cases of branches from trellises be-
fore alluded to answer this supposition. Some have thought that as the for-
eign vine, growing under glass, thrives there so well principally on account of
the humid atmosphere, the evaporation from the trees' foliage might benefit the
vine growing over it ; but it has been further observed that they grow as well
over dead trees as over living ones : and so on, in like manner, every theory
has been refuted, and the true reason unexplained.

I think Mr. Darwin's discovery of tendril motion will afford the key to this
phenomenon, and enable us to form a new theory as to the origin and employ-
ment of force in vegetable growth.

Mr. Darwin has shown that the tendrils of plants are in continuous motion
for a long time until they find something to cling to, when motion at once

1866.] 26

402 PROCEEDINGS OF THE ACADEMY OP

ceases. Motion is an attribute of vital force ; and vital force, whatever be its
origin, must be sustained by nutrition.

There are two forms of motion. The one we call growth, which is the mo-
tion of the cells individually; the other, in animals, we call muscular motion,
is the movement of the cells collectively. This tendril motion, unnamed be-
cause until lately unknown, is analogous to animal muscular motion, in its
being a collective movement of the parts.

In animals we know that nutrition will only suppty a given amount of force,
and that if muscular motion receives an undue proportion of this force, growth
(cell motion) suffers. In common language, the over-run horse gains no flesh.
On the other hand, the disuse of muscular power fattens the animal. If the
same division of motion exists in plants, and Mr. Darwin's paper shows it does,
it necessarily follows that if one form gets more than, its due share, the health-
ful balance is destroyed — in other words, the force necessary for excessive .ten-
dril motion in the grape vine exhausts the nutritive powers of the plant to sup-
ply ; growth suffers, and disease ensues.

To apply this principle to the case of unsuccessful grape culture, we find in
no system of grape management is any provision made for arresting tendril
motion, — but on the tree thousands of little twigs invite the tendrils at every
turn. No motion is expended except for what we might almost term healthful
exercise, — the balance is used in growth.

Observation on many species of climbing vines under similar circumstances
confirms these views. The growth and general healthfulness of every kind of
vine, is in exact proportion to the climbing facilities afforded it. The garden
pea will furnish a ready means of testing this proposition. It will be found
that difference in vigor, general healthfulness, and longevity, is strikingly in
lavor of those grown on twiggy brandies. Peas unstaked grow weakly, bear
early and sparingly, and die young. Honeysuckles ramble to great heights and
have large luxuriant foliage on fine wire trellises, but when dangling to one
straight stick they grow very little indeed. The most striking instance that
came under my observation was in some Wistaria sinensis which had been
trained to form self-supporting dwarf trees. The branches would only grow
two or three feet in a season, but a few of the shoots in time bending over and
reaching the ground, where they found a natural support, would grow
thirty feet during a single season. The observations in this way were so uni-
form, and the materials being everywhere, any one can verify this without it
being necessary for me to particularize further instances.

Every effort of nature is but an endeavor to accomplish an object. The his-
tory of a plant's life is a struggle with gravitation. The purpose of that strug-
gle is with the Author of its existence, but its immediate object is to elevate
itself from the earth. The force required for this is very great. In its young
days, however, it. goes on with vigor, — taking no thought, as it were, of to-mor-
row,— but, as it grows older, it becomes bowed down by the weight of its own
accumulations ; gravity tells on its wide-spreading branches, reminding it of
its growing weakness. It then prepares itself for its final dissolution by pro-
ducing fruit, which, fully accomplished, the struggle with gravitation ceases,
and dust to dust returns.

The whole of this enormous motive force must, as we have seen, be derived
from nutrition, — and the proper proportion due to each form of motion must
be provided and paid to it, or deranged action be the inevitable consequence.

One of the most abundant of the larger insessorial birds of Eastern North
America, retaining its place in the most highly cultivated districts, associated
in societies at all seasons, and in the migrating periods, especially in autumn,
appearing in immense flocks in the Middle and Southern States. Numerous
colonies remain during the summer, and rear their young within the corporate
limits of Philadelphia, and resort constantly to the. public squares (or parks) in
the most densely populated parts of the city, for the purpose of feeding on the
larvae of insects, especially of species of Lepidoptera, which infest the trees. In
some instances small parties have built nests and reared young in the public
squares of this city, but this bird evidently prefers the suburbs and open
country.

Bill about the length of the head, thick at base, curved at the end, edge of
upper mandible generally sinuated, commissure nearly straight, but curved
downwards distinctly at the point; wing moderate, with the third quill usually
slightly longest, but frequently about equal to the second and fourth ; tail
rather long, graduated ; legs and feet rather strong ; claws strong and sharp.
Total length 11 J to 13 inches ; wing 5 to 5 J ; tail 5^ to 6 inches.

Adult male. Entirely black, head, neck and breast with a fine steel-blue,
greenish-blue or violet-blue lustre, abruptly terminated on the neck behind,
extending on the breast in front, but abruptly terminated and giving place to
the fine golden and bronzed violet-blue, purple and green of the abdomen,
which are very nearly the same on the back and other upper parts of the body.
Coverts of the wing and shorter quills with fine bronze and bluish-purple lus-
tre, primaries narrowly edged with purple or bluish. Tail usually with a fine
blue lustre, but frequently changing to green ; bill and feet black.

The lustres of the plumage in this species (and in the next succeeding)
change in a considerable degree in different lights, and have an almost un-
limited variation in different ages and seasons, and even in individual speci-
mens of the same age apparently, and are difficult to describe. Frequently the
blue of the head and throat presents a green mixture or dominant lustre of that
color ; there is occasionally a well defined band on the back of the neck of a
fine golden and green lustre, and also frequently a large mixture of blue in the
lustres of the abdomen ; and lastly, the plumage of the back and abdomen
presents all these lustres with the feathers edged or tipped with fine golden,
green or violet, forming a singular iridescent character.

Adult female. Smaller than the male, with the lustres of the plumage

generally similar, but with generally a greater prevalence of green, and a
paler violet lustre than in the male. Total length about 10^ to 11£ inches.

to appear on the head and breast, wings and tail.

fourth quills very nearly equal ; tail rather long, graduated ; legs and feet
strong, claws strong and sharp. Total length about 10J to 12 inches ; wing 4|-
to 5 J ; tail about 5 inches.

Adult male. Entirely black, head, neck and breast with a fine blue lustre,
changing to a fine golden purple or violet, abruptly terminated on the neck
behind, extending lower on the breast, and abruptly giving place to a silky
green lustre on the abdomen, somewhat mixed or variegated with purple and
violet. Back with nearly the same lustre as the abdomen ; rump and upper
tail coverts more variegated with golden green, violet and blue. External wing
coverts with fine blue lustre, changing to green, and frequently tipped and
edged with golden-green and violet. Shorter quills with fine blue lustre
changing to green. Primaries narrowly edged with bluish or green. Tail with
a fine green lustre ; bill and feet black.

In this species the lustres of the plumage seem to be more uniform, or much
less changeable or broken than in the preceding ; and in all the specimens now
under examination the shorter quills have a nearly uniform fine blue lustre,
changing to green, and more uniform than in the preceding, and the tail has a
green instead of blue lustre. These characters of the plumage, and the smaller
size and longer bill, furnish characters at once available for the easy recogni-
tion of this species. It is strictly of the same subgeneric group as the prece-
ding, and the two are the only species known to me which present variegated
and iridescent lustres of plumage. The two species form a subgroup which I
regard as typical Quiscalus.

2. Iloloquiscalus.

All the species of this subgroup, known to me, are black, with purple or
violet lustre of various shades in different species, wings and tail uniformly
with greenish lustre. In any one species the lustre is nearly uniform on all
parts of the head and body. These species inhabit the West Indies and the
continent of America as far north as Mexico.

In the large collection of Quiscahnse in the Museum of the Smithsonian Insti-
tution, from the West Indies, in which the localities are most carefully and
accurately stated in the labels by Professor Baird, I have not succeeded in
finding any one species from more than one of the larger Islands. In other

[Dec.

words, it is my conclusion that at least the larger Islands, — Cuba, Jamaica, St.
Domingo and Porto Rico, — are each inhabited by a distinct species. That of
Trinidad seems to be the same species inhabiting South America.

1. Gracula barita is a name given by Linnaeus in the 10th edition of Syst. Nat.
i. p. 109 (1758), and he probably describes from a specimen collected by Dr.
Rolander, whose name he mentions, without citing any work or manuscript
and without giving locality, other than " Habitat in Americse Musis, cuius fructus
deuastat. Rolander," which, being interpreted, means that the locality is in
those parts of America where plants of the genus Mum (the plantain and
banana) flourish. The description, very probably, is that of a bird in plumage
not mature, but of this group, and is applicable with about equal propriety to
the young of any species of the subgroup here indicated as Iloloquiscalus. Dr.
Rolander visited Guiana and the Island of St. Eustatius, but published nothing-
relating to his ornithological collections, to my knowledge It is impossible to
determine the species or the locality from Syst. Nat. loth edition, or in any
other manner in especial relation to that edition, of which the present writer
is cognizant.

3. Brisson, in Orn. ii. p. 103, under the name Icterus niger, describes speci-
mens in the collection of M. de Reaumer, from Jamaica and St. Domingo : "On
le trove a la Jamaique et a St. Domingue d'ou il ete envoye a M. de Reaumer
par M. Chervain." He gives as a synonym " Monedula tota nigra," Sloane, as
above cited, who described, of course, from specimens obtained in " the hot and
distant Island of Jamaica," and, whatever the St. Domingo bird may be, Bris-
son also describes and figures that of Jamaica, uow well known, and usually
called Q. crassirostris.

Sturnus jamaicensis is a name given by Daudin to the bird described under
the name "Merops niger, iride sub-argenteo,'' by Dr. Patrick Brown, in Nat, Hist.
Jamaica, p. 476, which is undoubtedly this bird. Daudiu is in error, however,
when he gives " Monedula tota nigra," Sloane, as a different bird, though he is
quite correct in applying to it the name Gracula barita, Linn. (Daud. Tr.
d'Orn. ii. p. 320 )

There is, in my opinion, sufficient evidence that this species of Jamaica is
properly to be regarded as entitled to the name Quiscalus buriius, (Linn.) In
late authors this name has usually been applied to the species from Cuba,
which has no claim whatever. The present bird is stated to inhabit also St.
Domingo by Mr. Gosse, in Birds of Jamaica, p. 220, but I have seen no speci-
mens of it from that Island, nor from elsewhere than Jamaica.

Numerous specimens of this species are in the collection of the Smithsonian
Institution and in the Academy Museum, and are exclusively from Jamaica. It
is rather the largest of the group inhabiting the West Indies and has the bill
thick in both mandibles, curved in its terminal half, commissure inflexed and
curved at the end of the bill ; wing long, third and fourth quills longest and
nearly equal ; tail long, graduated ; legs and feet strong. Male larger than
the female,

Numerous specimens in the Smiths. Mus. and in the Acad. Mus., exclusively
from Cuba. This species is but little smaller than the preceding, the bill is
more slender and more gradually pointed and the tail seems to be compara-
tively longer. The color of the head and body in the Cuba bird presents a
more decided purple or violet lustre than in that of Jamaica, and the under
parts have a fine golden purple lustre quite wanting in the species of that
Island.

Similar in form and general lustres of plumage to the immediately preced-
ing, but rather smaller; bill more pointed and more gradually tapering ; tail
comparatively longer. Bill longer than the head, gradually curved and pointed ;
wing moderate with the third and fourth quills usually longest, but frequently
about the same length as the second ; tail rather long, graduated, the feathers
wide ; legs and feet strong ; claws curved, sharp. Total length about 1 1 J to 12
inches, wing about 6, tail 5| to 6]- inches.

Adult male. Black, head and body above with a fine purple or violet lustre ;
under parts with a fine golden purple lustre ; wings and tail above with a green
lustre ; smaller wing coverts purple changing to greenish ; tibia? and under
tail coverts greenish ; bill and feet black,

Female. Smaller. The specimens now under examination are not sufficient
to be reliable in either the lustres of the plumage or dimensions in the female.
Those which I regard as females are very similar to the males in lustres of
plumage, and there does not appear to be so much difference in the sizes of the
two sexes as in the species of Jamaica.

It is with great gratification that I name this species in testimony of my
high estimation of Dr. John Gundlach. a most excellent and accurate natural-
ist, who has with great ability studied and made known especially the orni-
thology of the Island of Cuba. The researches of this gentleman have in fact-
been of the greatest value in the Natural History of that Island.

5. Quiscalus brachypterus, nobis.

Numerous specimens in the collection of the Smithsonian Institution from

This species resembles those from the Islands of Jamaica and Cuba, Q.
baritus, (x>. Gundlachii, especially the latter, but is smaller, with the bill more
slender; the tail shorter, and the wing disproportionately shorter. The last
character is the most immediately available in distinguishing from either of
those species. This bird is larger than cither of the succeeding in this memoir.

Bill about the length of the head, gradually tapering and curved at the tip;
wing short, third and fourth quills longest; tail moderate or rather long ; legs

Sixteen/specimens of this species are in the Smiths. Mus. from the Island of
Porto Rnco and one specimen from the Massena collection without label, in
the Acad. Mus. It resembles other species of this group in colors and lustres
of plumage, being most nearly related to those above mentioned from Jamaica
and Cuba, with which it has usually been confounded. It is distinguishable
without difficulty, on examination, by its short wings and tail. This is un-
doubtedly the species alluded to under the name " Quiscalus barita" by Mr. E.
C. Taylor in Ibis, 1864, p. 168, and stated by him to be very abundant in Porto
Rico.

Specimens of both sexes in the Smiths. Mus. from the Island of St. Domingo
or Havti, and distinct specifically from either of the preceding or any other
species known to me. This is, in my opinion, undoubtedly the bird figured by
Buffon as cited above, but not with entire success, the tail not being sufficiently
" etagee," though so described in his text. This figure is about the size of the
female ; the bill and feet are too lightly colored. It probably represents the
female in plumage not mature.

This species is smaller than either of the preceding, the male being rather
smaller than the female of the Cuba species, Q. Gundlachii, and the female (in
this species) much smaller than the male. The bill is straight, and gradually
pointed, not curved, more slender than in either of the preceding, and the
commissure nearly straight ; wing moderate, third and fourth (prills longest
and nearly even; tail rather long, graduated; legs and feet rather strong.
Easily distinguished from either of the preceding by its straight, sharp bill.

One specimen only in the Acad. Mus. seems to be this species, but which is,
unfortunately, without label stating locality. The bill is exactly the length
and otherwise very nearly as given by Mr. Swainson as cited above, though
somewhat thicker. It is the only specimen that I have ever seen in which the
commissure is an uninterrupted curve or arc of a circle, — not straight nor sin-
uated as in all other species known to me (except Q. niger of St. Domingo)
and described in this memoir. It is apparently adult, but probably in not
quite mature plumage.

Male nearly adult? Bill rather longer than the head, curved, the upper
and under mandibles nearly equal in thickness, commissure curved and the
edges of both mandibles indexed ; wing moderate, second, third and fourth
quills longest and very nearly equal ; tail moderate or rather long, graduated ;
legs and feet strong. Total length about 10 inches, wing 5, tail A\ inches,
tarsus about 1^, chord of upper mandible about one and four-fifths inches.

fully mature, the tail is plain black. Bill and feet black, the latter (feet)

collection.

The lustres of the plumage in this species are generally similar to those of
all the other species of the sub-group here designated Iloloquiscalus, but the
purple is rather darker than in either. The specimen now described is prob-
ably not mature in plumage, and the lustres of the plumage, therefore, not
entirely reliable as characters.

Of all the specimens that I have seen of Quiscali, this comes the nearest to
Mr. Swainson's description and figure of Q. inflexirostris, and in fact there is no
other that I can suspect as possibly that species, on account of the peculiarly
curved bill. No locality is known to me, and at this time I do not remember
ever having seen the species mentioned by any writer since Swainson.

This is another of the species of this difficult group, with the lustres of the
plumage uniform purple on the head and body, and green on the wings and
tail. It is rather smaller than the species immediately preceding (Q. inftexiros-
tris) and decidedly smaller than all others preceding. Specimens from Trini-

but rather abruptly curved at the point ; wing rather long, third and fourth
quills longest and nearly equal ; tail rather long, graduated ; legs and feet
strong. Total length about 9i to 10 inches, wing 4£ to 4|, tail 4 to \\ inches.

The largest specimen now before me is from Trinidad, all the measurements
of which are rather larger than as given by Mr. Swainson in his description,
as above cited. The smallest is probably from Brazil, and is that which at
present I regard as described by Dr. Cabanis as C. minor as above. In all the
species of this group, of which I have series of specimens, there is some diver-
sity of size, and, finding no other appreciable character than this diversity in
the specimens now under examination. I regard them as one species. This bird
seems to be the most common species of South America and of the Island of
Trinidad.

9. Quiscalus mexicanu's, nobis.

A single specimen in the Acad. Mus., selected with other birds from a large
collection made in Mexico by M. Bruzin, is different from either of the preced-
ing species. It is one of the smaller species and most resembles the immedi-
ately preceding (Q. lugubris), but is rather larger and has the bill much stronger
aud more curved Its colors and lustres are nearly the same as that species,
but seem to be of a richer golden-purple lustre on the under parts (as in some
species of Molothrus and in Q. Gundlachii of Cuba.)

Adult male. Bill longer than the head, thick, curved, especially in the
terminal third of its length ; wing moderate, second and third quills longest ;
tail moderate, graduated; legs and feet strong. Total length 9| to 10^
inches, wing 4.], tail 4} to 4.} inches.

10. QlTISCALUS RECTIROSTRIS, nobis.

This is a small species, of which one specimen is in Acad. Mus. without label
stating locality. It is quite distinct from any other, though of the same gen-
eral colors or lustres of plumage and is strongljr characterized by its straight,
slender and sharp bill. It is smaller than either of the preceding, though the
present specimen may be a female.

Bill straight or very slightly curved at the tip, slender, gradually tapering.,
pointed, under mandible rather the thicker, commissure straight, edges in-
flexed ; wing moderate, third and fourth quills longest and nearly equal; tail
rather long, graduated ; legs and feet moderate ; claws curved, sharp. The
tail is scarcely as long, proportionately, as in other species of this sub-group,
and the legs, toes and claws rather more slender. Total length about 9i
inches, wing 4o, tail 4 inches. Female?

Adult ? Black, entire plumage with a dark purple lustre very slightly
changing to greenish on the wings and tail. Bill and feet black. In the spe-
cimen now described the shorter quills and wing coverts have the same purple
lustre as the body, while the edges of the primaries have a faint green lustre
scarcely preceptible, in which character this bird is peculiar in this sub-group.
Iu this specimen the under mandible is pale at the base, and the quills on their
under surface have a brownish tinge.

Ilab. — Unknown. Spec, in Mus. Acad., Philada.

This is a quite peculiar species, easily recognized amongst the birds de-
scribed in this memoir, by its straight slender bill. It seems also to have more
slender legs and feet and perhaps rather shorter tail than usual, though these
characters are scarcely to be relied on in prepared and dried specimens. The
entire plumage in mature age, has, I suspect, an entirely uniform dark purple
lustre, including wings and tail, or perhaps slightly greenish on those parts
only.

The seven species last above given (Nos. 3. to 10 of this memoir) are all that
I consider myself justified in regarding as entitled to be established and be-
longing to this sub-group, which I have designated Holoqaiscalus. In the
Academy Museum, however, there are several specimens in plumage not
mature, but probably of this sub-group, which I cannot refer to either of
these species and my present opinion is that there are other species yet
unknown.

The species of this sub-group are the largest of the genus Quiscalus. They
are easily recognized by their size, robust organization and long and graduated
tails..

Specimens in Acad. Mus., without labels, from the Massena collection and
one specimen from Mexico in the Smiths. Mus., undoubtedly of this species and
clearly distinct from either of the preceding. The females are much lighter
colored than those of either Q. major or Q. macrourus, and easily to be distin-
guished, and in this species the slender bill is a strong and apparently reliable
character. It is carefully given by Mr. Swainson as above cited, and his de-
scription is quite sufficient for the identification of the species.

About the size of Q. major ; form lengthened and not so robust as in either
of the preceding ; bill much more slender, nearly straight ; wing long, third
quill longest ; tail long, graduated, outer feathers about 3 inches shorter than
those in the middle of the tail ; feet and claws more slender than in the pre-
ceding species.

Adult male. Black, the entire plumage with a fine purple lustre inclining
to steel blue on the wing coverts and upper tail coverts. Wings and tail with
a slight bluish lustre. Bill and feet black. Total length about 15 inches,
wing 6i to 7, tail 8 inches.

Female. General^ resembling the females of the preceding two species, but
much lighter colored. Head above and neck behind light brown, inclining to
chestnut or bay color ; back, wings and tail dark brown, or nearly brownish
black. Under parts light, dull yellowish brown, much paler on the throat ;
tibiae and under tail coverts dark brown. Total length about 11 to 12 inches,
wing 5]-, tail 5.] to 6 inches.

Hah. — Mexico. Spec, in Mus. Acad., Philada., and Smiths. Inst., Washington.

This is an entirely respectable species, though apparently not much known
to naturalists. It belongs strictly to the sub-group of Quiscalus to which the
name Megaquiscalus is given in this memoir, all the species of which are char-
acterized by their large size and long tails. This bird is easily recognized by
its slender bill, and in the adult male the lustre appears to be nearly uniform
purple with little change or variation in any exposure to the light. The
female can easily be distinguished from that of either of the preceding by its
lighter colors, and especially by the quite different color of the head above and
neck behind. In one female specimen in the Massena collection the throat
might be described as dull j-ellowish white, and the entire under parts of the
body but little darker. One female specimen in the Mus. Smiths., undoubtedly
from Mexico, clearly determines the locality of this species.

In one of the interesting and valuable collections from North Western Mexi-

United States Army, I am greatly gratified to find two specimens of a species
quite unknown to me previously, and which seem to be the Mexican bird de-
scribed by Swainson as above cited. These specimens are not in adult plu-
mage and are not quite so large as the dimensions given, but they are evidently
assuming the colors as given in the description, and I have no doubt are the
species. From Mazatlan, Mexico.

Mr. Swainson's description is : " Glossy blue black ; thighs brown ; bill
slender, commissure straight; legs slender; claws long, slightly curved.

The specimens now before me are probably very nearly full grown, but have
not entirely assumed the "glossy blue black," though that color is plainly su-
perceding the immature plumage. The brown of the tibise is to be seen in
both specimens.

This is a common species of Central and Western North America and
Mexico, of which numerous specimens are in the Smiths. Mus. and Acad. Mus.

Bill shorter than the head, thick at the base, conical, pointed ; wing long,
pointed, second quill longest ; tail moderate, rounded ; legs and feet rather
slender. Tot# about 9£ to 10 inches ; wing 5 to 5J, tail 4{- to 4£ inches.
Sexes nearly of the same size.

Adult male. Black, head only with bluish violet or purple lustre, all other
parts with fine green lustre ; bill and feet black.

Female. Dull brown, with a plumbeous tinge, lighter on the head and
breast, and frequently tinged with rusty or dull yellowish ; back darker : tail
and wings generally with greenish lustre. The young of both sexes have
nearly the entire plumage dull rusty brown, especially the head and under
parts of the body, but more as a color of the plumage, as in Molotkrus, than
with the feathers merely edged, as in S. ferrugineus.

Apparently confined to the Island of Cuba. This is another of the robust
species, with the bill short and thick, and tail of moderate length and rounded
at the end.

About the size of, and general form very similar to the last species (S. Dives),
but with the wing longer {and lustre of plumage entirely different). Bill strong,
thick at base, and rather abruptly tapering, pointed ; wing moderate, third and
fourth quills longest; tail rather long, rounded ; legs and feet strong.

Adult male. Black, the head and entire body above and below with rich
violet or purple lustre ; wings and tail with green lustre. Shorter quills edged
with violet, smaller wing coverts violet, greater coverts and quills edged with

One specimen from the Massena collection in the Acad. Mus. seems to be this
species, though not in all particulars corresponding with Dr. Sclater's diagno-
sis, as above cited. It is smaller than either of the preceding species of the
subgroup herein designated Dives.

III. Genus IDIOPSAR, nobis.

In the collection of the Smithsonian Institution I find a specimen of a very
interesting and singular bird, evidently letcrine, and allied to Quiscalus and
Scolecophagus, but not to be referred with any considerable degree of propriety
to either of those or to any other genus of this group. The tail is short, nearly
even at the end, and emarginate, and the wings long. General form short and
compact, bill about the length of the head, strong, slightly curved, with the
commissure much inflexed in both mandibles, culmen distinct. Legs and feet
moderate.

1. Idiopsar brachyurus, nobis.

Entire plumage of the head and body bluish cinereous or plumbeous, darker
on the upper parts and lighter on the under parts, nearly white at the base of
the under mandible, quills dark ashy brown, primaries edged externally with
light ashy nearly white; tail feathers dark brown, nearly black, edged with
light ashy. Lower abdomen or ventral region light ashy nearly white. Bill
dark horn color, under mandible lighter, especially at the base. Tarsi and
toes light brown.

Total length about 7£ inches, wing 4, tail 2|, bill 1 inch.

1. Potamopsar minor (Spix.)

Icterus minor, Spix At. Bras. i. p. 67 (1824.)

Spix At. Bras. 1 pi. 63, fig. 2.

Frontal feathers short, erect and rigid. Bill shorter than the head, rather
slender, and abruptly tapering, pointed ; wing rather short, third, fourth and
fifth quills longest and nearly equal; tail rather long, graduated; legs and feet
moderate, or rather slender.

Total length about 9 inches, wing 4, tail 4 inches.

Adult male. Entirely bluish black, with little or no lustre and nearly uniform
on all parts, including the wings and tail. Bill and feet black.

Hab. — Rio Napo (Mr. Lawrence), Rio Javarri (Mr. J. Verreaux).

It is perhaps expedient to follow Dr. Sclater in regarding this bird as Icterus
minor, Spix, as above cited, but neither the figure nor description of that author
will quite establish its claims satisfactorily. If really the' species of Spix, it is
one of his worst figures and descriptions, which is saying much !

This is a rare species in American collections, the only specimens that I have
seen being one in the Smiths. Mus , from Mr. Verreaux, labelled " Rio Javarri,"
and another, in my friend Mr. Lawrence's collection, labelled " Rio Napo,"
both undoubtedly correct.

Quiscalus.

This is a group easily distinguished generically, especially by the strong bill
flattened above, and in adult plumage by the somewhat lengthened and proba-
bly partially erectile plumage of the neck. The color is black in all the spe-
cies, and in my opinion is always lustrous in the adults of both sexes. In the
young Lit all species known to me the color is dull or plain black. Specimens
in plumages not mature are much the more common in all collections, and
such have been repeatedly described, but very doubtfully to the comfort of the
student. It is quite impossible for me to coincide with those authors who re-
gard this group as but one species, and that by a name which is of quite
doubtful application to any !

now before me are from Brazil, Cayenne, Ecuador and New Grenada, and are
quite identical with each other throughout, and in my opinion different speci-
fically from the species of Central America and Mexico, though about the same
size.

Large, entirely black, the upper parts having a fine bronzed yellowish and
greenish lustre, becoming violet on the rump and upper tail coverts. Bill very
strong and wide at base, curved in its upper outline, pointed, flat above and
extended into the frontal plumage, terminating in a semicircle. Plumage of
the neck rather full and long, and partially erectile. Wing long, pointed, first
quill longest, tail moderate or rather long, rounded, feet and legs strong, claws
sharp.

Total length about 14 to 16 inches, wing 7 to 8, tail 6 to 6 £ inches (adult).

PROCEEDINGS OP THE ACADEMY OP

Hob. — Brazil, Ecuador. ^Probably inhabits nearly all of South America.
Spec, in Mus. Acad., Philada., and Smiths. Mus., Washington.

Easily distinguished from the species immediately succeeding (C. Mexicanus)
by the bronzed and yellowish lustre of the upper parts in the adult, which is
always present but varies much in extent (in the adult plumage only). The
entire head is fine blue, and the under parts have a yellowish violet lustre :
wings and tail purplish black. The bronzed lustre of the upper parts varies
according to age or stage of plumage, and is frequently restricted to a wide
transverse band across the upper part of the back and neck behind, and is to-
tally wanting in the young bird. The entire plumage in this species has fine
brilliant lustres, as herein described, except the wings and tail, which are rich
purplish black.

The young in this species has the bill always thick and strong, though not
so long as in the adult. The entire plumage (in the young) is brownish black,
frequently with the tips and edges of feathers showing some lustre. Total
length of young usually about 12 inches. The two descriptions of Mr. Swain-
son, cited above, I regard as very probably those of the adult and young of this
species.

This is apparently an abundant species of Mexico and Central America.
Specimens in the Smithsonian Museum, from Mexico and Guatemala, and in
Mr. Lawrence's collection from Panama. It is easily distinguished, in adult
plumage, from the preceding by its fine violet purple lustre, nearly uniform on
the upper and under parts ef the body (not bronzed yellowish and greenish, as
in the preceding, C. ater).

Large, entirely black, with a fine violet purple lustre on the body above and
below; head bluish violet; wings and tail fine purplish or greenish black. Bill
very strong, thick, curved in its upper outline, pointed, flat above and extend-
ed into the frontal plumage, ending in a semicircle ; wing long, pointed, with
the second quill slightly longest ; tail rather long, rounded ; feet and legs
strong; claws curved, sharp. Total length 14 to 15 inches, wing 7£ to 8, tail
6 to 6J inches.

Young. Bill thick and strong as in the adult, but shorter ; entire plumage
dull brownish black, or with feathers edged and tipped with the lustres of the
adult. Total length usually 12 or 13 inches.

About the same size or slightly smaller than the preceding, with the legs and
feet rather stronger. Easily distinguished in adult plumage, but the two spe-
cies are very similar and scarcely distinguishable in young plumage, both be-
ing nearly uniform brownish black. This is very probably the species named
by Lesson, as above, but whether it is the Corvus mexicanus, Gmelin, may be
difficult to determine.

This is a species much smaller than either of the preceding, and is, perhaps,
that figured by Mr. George Robert Gray in his great work, "The Genera of
Birds," as bove cited. For the purpose of more fully understanding this spe-
cies, I copy the original description of Latham, on the faith of which, only,
Gmelin gave the name : —

"Length nine inches. Bill an inch and a half long, black, stout, sharp, a
very little bent at the tip; flat on the top towards the base, where it is round-

ed, and passes far back on the forehead, and is there a little protuberant like
the former ones : the general color of the plumage is black ; the head, neck
and breast have a fine purple gloss ; the whole wing, and rest of the body,
black ; the tail consists of twelve feathers, and was five inches in length, but
had been longer, as the ends were spoiled ; the wings reached a little beyond the
insertion of the tail ; the legs were wanting."

" I found this species in the collection of Miss Blomefield ; it was supposed
to come from Cayenne. A label annexed gave_it the name of Oiseau de Ris
de grosse espece."

At present I have seen, in adult plumage, no specimen small enough to be
properly or without misgiving regarded as the species described by Latham,
nor do I quite understand the " protuberant " character of the bill as stated by
him. Further, in all specimens that I have seen the wings reach so far be-
yond the insertion of the tail that his description in that particular is by no
means applicable, and on the whole I am not without suspicion that this de-
scription is not of a bird of the genus Cassidix at all. This description is the
sole foundation of the species, if such it is, and the name, as given by Gmelin
on the faith of it, has been applied by nearly all late authors, evidently on the
supposition that there is one species only extant, which supposition I regard as
erroneous, and as probably so, the application of this name.

At present (assuming that this may be a species of Cassidix), two specimens
now before me, it is possible to refer to it, and so also is the bird figured by
Mr. Gray, as above. The two specimens before me are in young plumage, and
are the smallest of this genus that I have ever seen. The bill is smaller and
more slender than in either of the preceding, especially the upper mandible.
One specimen from the collection of my friend Mr. Lawrence, of New York, is
adolescent, the plumage on the body showing some edgings of purple lustre,
nearly uniform above and below. This specimen is from Brazil ; the other
specimen is in the Acad. Mus., and without label, stating locality. It is nearly
uniform brownish black, as in young birds of other species of this genus, but
with numerous traces of bluish purple lustre.

Mr. Gray's figure, which I regard as probably representing the nearly adult
of the same species as the two young birds here mentioned, is that of a bird
about 10£ inches in total length, of nearly uniform bluish purple color. The
young bird in the Acad. Mus. measures, total length 10 inches, wing 6, tail A\
inches.

4. Cassidix Vieilloti (Bonaparte).

Scaphidurus Vieilloti, Bonap. Consp. Av. i. p. 426 (1850).

In the very extensive and valuable collection of birds of Central and South
America now belonging to the Smithsonian Institution, I find one specimen,
which, though in young plumage, may be different from either of the species
above mentioned. It is labelled, in the handwriting of Mr. Jules Verreaux,
" Scaphidurus Vieilloti, Bonap.," and the conclusion of that most accurate and
excellent ornithologist is always entit.ed to great respect and consideration.
The following is Bonaparte's diagnosis : —

"Sc. Vieilloti, Bp. (Cassicus niger? Vieill.) Gal. Ois. t. 89? ex Cayenna, An-
tillis. Mus. Darmstadt. Statura media, remigibus primit qualuor apice emargi-
nato dilitatis."

This specimen is in young plumage, being nearly uniform brownish black,
the bill slender, comparatively, and more narrow above than in any other I
have seen. The primaries are wide, but not especially so at their ends, and
have a slight emarginate character at their tips. Total length about 11^
inches, wing 5£, tail 4J inches. " Young male."

At present I regard this as the fourth species of Cassidix with which I am
acquainted.

REPORT OF THE CURATORS,

For 1866.

The Curators, in presenting their Annual Report, take the opportunity of
expressing their satisfaction and pleasure in the prospect that their suggestion
of the last Report, in relation to an increase of accommodations for the over-
crowded Museum and Library, is likely to be carried out. The success of the

[Dee.

NATURAL SCIENCES OP PHILADELPHIA. 419

Committee on the Building Fund, created for the purpose of obtaining means
for the purchase of a suitable lot of ground and the erection of a new and
larger Hall for the Academy, should encourage us to renewed efforts to secure
the most ample means for the objects of the Institution.

The Curators further take pleasure in announcing to the Academy that the
Museum, committed to their charge, is in a far better condition of preservation
than in the previous years. The liberal appropriations made by the Academy,
of which only three-fourths were expended, through the exertion of our asso-
ciate, Mr. Cassin, has enabled us thoroughly to disinfect and put in good order
our magnificent collection in ornithology.

Without expense to the Academy, under our direction and through the aid
of several members, students operating under the Jessup Beneficiary Fund,
the American Herbarium has not only been renovated, but all the plants have
been poisoned so as to secure them from future depredation, and now the
same process is being carried on with the General Herbarium. Through similar
aid, we have been enabled to put the Entomological Cabinet in good order.
All other portions of the Museum are in an excellent state of preservation.

The following account exhibits the contributions to the Museum of the
Academy in its various departments during the year :

Mammals and Birds. — Eight specimens of the former were presented by Mrs.
Mary Brainerd, C. J. Wood, A. H. Smith and Drs. J. F. Meigs and W. Camac.

One hundred and sixty-five specimens of 90 species of birds, chiefly from
Western America and the West Indies, were presented by the Smithsonian In-
stitution. Fifty-three specimens of 31 species were presented by Dr. H. B.
Butcher; and 28 specimens, mainly in young plumage, by C. J. Wood. Seven-
ty-three specimens were presented by W. S. Vaux, E. D. Cope, J. Leidy, J. F.
Cavada, Dr. E. Coues, C. S. Westcott, Jos. Jeanes, R. Bridges, J. G. Bell, T.
Julius, E. P. Borden, and Dr. W. A. B. Norcom.

Reptiles and Fishes. — Twenty-three specimens of the former, and 18 of the
latter were presented by Dr. Lemuel J. Deal, S. Powel, Miss Sallie Bridges, E.
Diffenbaugh, W. C. Henszey, and R. J. Hardie. Small collections of both were
also presented by Dr. Slack, and Mr. Hoopes.

Mollusks. — Thirteen hundred species of shells, of which 793 were new to our
Museum, were presented by the Smithsonian Institution. Mr. Tryon presented
84 species of shells, in addition to a small collection. Dr. C. J. Cleborne pre-
sented a collection of 140 species. Ninety-five species, in addition to several
small collections, were also presented by Rev. E. R. Beadle, John B. Eshleman,
T. A. Conrad, I. Lea, J. H. Thompson, Dr. LeConte, C. F. Parker, Miss Bridges,
Col. Jas. Greer, Patricio Paz, E. Gaussoin, Dr. E. Michener, S. Powel, and Dr.
Ruschenberger.

Articulates. — James H. B. Bland presented 207 specimens of 130 species of
Coleoptera. Eighty-eight species of insects were presented by Geo. A. Propper,
and 41 specimens of 35 species by Dr. H. B. Butcher. A few insects, crustace-
ans and worms, were also presented by Tryon Reakirt, Dr. C. J. Cleborne, C.
M. Wheatley, Geo. W. Tryon, Jr., R. A. Parrish, Jr., Dr. LeConte, K. K. Wom-
rath, W. McConnell, and S. Powel.

Radiates. — Of these, fourteen were presented by Dr. C. J. Cleborne, W. M.
Gabb, George W. Tryon, Jr., and Miss Bridges.

Fossils. — A collection of fossil fishes from the cretaceous formation of the
Upper Missouri was presented by George A. Propper. Sixty-four specimens of
fossils, together with several small collections, were presented by Dr. Geo. H.
Horn, Dr. A. C. Hamlin, W. A. Hendry, Col. James Greer, D. C. Collyer, E. D.
Cope, F. Ashurst, C. C. Abbott, Dr. W. Spillman, John Hanson, Mr. Da Costa,

mission of the public, two days in every week, except during the months of
April, May and June, when, by direction of the Academy, the Museum was open
five days per week. The number of visitors during the year was ^34,521, not
including those introduced personally by members, or admitted on other than
the public days, of which it is quite impossible to keep an account.
